10 Pollen filter renewal
1 The pollen filter (where fitted) is located under the engine bulkhead cover panel. 2 Refer to Chapter 12 and remove both svindscreen wiper arms. 3 Unclip the rubber
seal
from the relevant end of
the
top of the engine compartment bulkhead. 4 Unscrew the retaining fastener screws and pull out the fasteners securing the bulkhead cover panel in position. Release the cover panel Irom the base of the windscreen and remove it from the vehicle. 5 Pivot the pollen filter cover upwards and away then release the retaining clips and withdraw the filter from its housing (see illustration). 6 Wipe clean the filter housing then fit the new filter. Clip the filter securely in position and refit the cover. 7 Refit the trim cover, securing it in position with Ihe fasteners, and seat the rubber seal on
the
bulkhead.
11 Idle speed and ^
CO
content check J and adjustment ^
1 The idle speed is controlled by the ECU via a stepper motor located on the side of the throttle body and is not adjustable. 2 The exhaust gas oxygen content is constantly monitored by the ECU via the Lambda sensor, which is mounted in the exhaust down pipe. The ECU then uses this information to modify the injection timing and duration to maintain the optimum air/fuel ratio.
3 Experienced home mechanics with a considerable amount of skill and equipment (including a good-quality tachometer and a good-quality, carefully calibrated exhaust gas analyser) may be able to check the exhaust CO level and the idle speed. However, if these are found to be in need of adjustment, the car must be taken to a suitably-equipped Fiat dealer for testing using the special test equipment which is plugged into the diagnostic connector.
12 Steering and ^ suspension check
front suspension and steering check 1 Raise the front of the vehicle, and securely support it on axle stands (see Jacking and
vehicle support).
2 Inspect the balljoint dust covers and the steehng rack-and-pinion gaiters for spirts, chafing or deterioration. Any wear of these will cause loss of lubricant, together with dirt and water entry, resulting in rapid deterioration of the balljoints or steering gear. 3 On vehicles with power steering, check the fluid hoses for chafing or deterioration, and the pipe and hose unions for fluid leaks. Also check for signs of fluid leakage under pressure from the steering gear rubber gaiters, which would indicate failed fluid seals within the steering gear. 4 Qrasp the roadwheel at the 12 o'clock and 6 o'clock positions, and try to rock it (see illustration). Very slight free play may be felt, but if the movement is appreciable, further investigation Is necessary to determine the source. Continue rocking the wheel while an assistant depresses the footbrake. If the movement is now eliminated or significantly reduced, it is likely that the hub bearings are at fault. If the free play is still evident with the footbrake depressed, then there is wear in the suspension joints or mountings. 5 Now grasp the wheel at the 9 o'clock and 3 o'clock positions, and try to rock it as before. Any movement felt now may again be caused by wear in the hub bearings or the steering track-rod balljoints. If the inner or outer balljoint is worn, the visual movement will be obvious.
12.4 Rocking a roadwheel to check for wear in the steering/suspension components 6 Using a large screwdriver or flat bar, check for wear in the suspension mounting bushes by levering between the relevant suspension component and its attachment point. Some movement is to be expected as the mountings are made of rubber, but excessive wear should be obvious. Also check the condition of any visible rubber bushes, looking for splits, cracks or contamination of the rubber. 7 With the car standing on its wheels, have an assistant tum the steering wheel back and forth about sn eighth of a turn each way. There should be very little, if any. lost movement between the steering wheel and roadwheels. If this is not the case, closely observe the joints and mountings previously described, but in addition, check the steering column universal joints for wear, and the rack-and-pinion steering gear itself.
Suspension strut/ shock absorber check 8 Check for any signs of fluid leakage around the suspension strut/shock absorber body, or from the rubber gaiter around the piston rod. Should any fluid be noticed, the suspension strut/shock absorber is defective internally, and should be renewed. Note: Suspension struts/shock absorbers should always be renewed in pairs on the same axle. 9 The efficiency of the suspension strut/shock absorber may be checked by bouncing the vehicle at each corner. Generally speaking, ihe body will return to its normal position and stop after being depressed. If it rises and returns on a rebound, the suspension strut/shock absorber is probably suspect. Examine also the suspension strut/shock absorber upper and lower mountings for any signs of wear.

13 Auxiliary drivebelt{s) check % and renewal ^
Note: Fiat specify the use of a special tool to cooectfyset the drivebelt tension. If access to ibis equipment cannot be obtained, an
approximate setting can be achieved using the method described below. If the method described is used, the tension should be checked using the special tool at the earliest possible opportunity. 1 Depending on equipment fitted, one. two or three auxiliary drivebelts may be fitted. The alternator, power steering pump and air
conditioning compressor, as applicable, are each driven by an Individual drivebelt.
Checking 2 Disconnect the battery negative terminal (refer to Disconnecting the battery in the Reference Section of this manual). 3 Firmly apply the handbrake, then jack up

the front of the car and support It securely on axle stands (see Jacking and vehicle support}. 4 Remove the nght-hand front wheel. 5 Remove the inner cover from under the right-hand wheeiarch for access to the right-hand side of the engine. 0 Using a socket on the crankshaft sprocket boll, rotate the crankshaft so that the full length of the auxiliary drlvebelt(s) can be examined. Look for cracks, splitting and fraying on the surface of the belt: check also for signs of glazing (shiny patches) and separation of the belt plies. If damage or wear Is visible, the relevant belt should be renewed. 7 If the condition of the belt Is satisfactory, check Ihe drivebeit tension as described below.
Renewal
Alternator drivebeit Note: On certain models with power steering but without air conditioning, it will be necessary to remove the power steering pump drivebeit ffrst, as described below. 8 Where fitted, undo the bolts and remove the belt guard from the alternator. 9 Loosen the pivot and adjustment bolts then swivel the alternator towards the engine and slip off the drivebeit. 10 Unbolt and remove the crankshaft sensor from Ihe front of the engine (refer to Chapter 4A. Section 5, if necessary). 11 Remove the drivebeit from the engine. 12 When renewing a drivebeit. ensure that the correct type is used. Fit the belt around the two pulleys then swivel the alternator outwaids to take up any slack in the betL Adjust the tension correctly as described below. Power steering pump drivebeit 13 Slacken the bolts securing the power steering pump to the mounting bracket. 14 Slacken the adjusting bolt locknut and turn the adjusting boit until all the tension is removed from the drivebeit. 15 Undo the bolts and remove the pultey guard from the power steering pump then slip the drivebeit off (he pulleys. 18 Ensuring that the correct type of drivebeit is used, fit the belt around the pulleys and turn the adjusting bolt to just take up the slack in the belt. Adjust the tension correctly as described below. Air conditioning compressor drivebeit 17 Remove the alternator and power steering pump dnvebelts as described previously. 18 Slacken the bolts securing the compressor to the mounting bracket. 19 Slacken the adjusting bolt locknut and turn the adjusting bolt until alt the tension is removed from the drivebeit, then slip the belt off the pulleys. 20 Ensuring lhat the correct type of drivebeit is used, fit the belt around the pulleys and turn the adjusting bolt to just take up the slack In the belt. Adjust the tension correctly as described below.
15.7 Checking a valve clearance with a feeler blade
Tensioning 21 Correct tensioning of the belt will ensure that it has a long life. A belt which Is too slack will slip and perhaps squeal. Beware, however, of overtightening, as this can cause wear in the alternator, power steering pump or air conditioning compressor bearings. Note: Fiat recommend use of their special tensioning tool however the fallowing procedure will set the tension correctly. 22 The belt(s) should be tensioned so that, under firm thumb pressure, there is approximately 5.0 mm of free movement at the mid-point between the pulleys. To adjust the alternator drivebeit, slightly tighten the adjustment bolt then swivel the alternator outwards until tne beft tension Is correct. Fully tighten the adjustment bolt followed by the pivot bolt then refit the rpm sensor. 23 On models with power steering and/or air conditioning, fit the relevant drivebeit over the pulleys then turn the adjusting bolt until the tension is correct. Secure the adjusting bolt by tightening Ihe locknut, then tighten the remaining mounting bolts. Refit any remaining dnvebelts and all the components removed. 24 Refit the inner cover and wheel, lower the vehicle to the ground, then reconnect the battery negative terminal,

engines which utilise self-adjusting hydraulic tappets. 1 The importance of having the valve clearances correctly adjusted cannot be overstressed, as they vitally affect the performance of the engine. Adjustment should only be necessary when the valve gear has become noisy, after engine overhaul, or when trying to trace the cause of power loss. The clearances are checked as follows. The engine must be cold for the check to be accurate. 2 Apply the handbrake then jack up the right* hand front of the vehicle and support on an axle stand (see Jacking and vehicle support). Engage 4th gear. The engine can now be rotated by turning the right-hand front road wheel. 3 Remove all spark plugs as described In Section 19. 4 Remove the camshaft cover as described In Chapter 2A. 5 Each valve clearance must be checked when the high point of the cam lobe is pointing directly upward away from the cam follower. 6 Check the clearances In the firing order 1-3-4-2.

cylinder being at the timing bell end of the engine. This will minimise the amount of crankshaft rotation required. 7 Insert the appropriate feeler blade between the heel of the cam and the cam follower shim of the first valve (see illustration). II necessary alter the thickness of the feeler blade until it is a stiff, sliding fit. Record the thickness, which will, of course, represent the valve clearance for this particular valve. 8 Tum the engine, check the second valve clearance and record it. 9 Repeat the operations on all the remaining valves, recording their respective clearances. 10 Remember that the clearance for Inlet and exhaust valves differs • see Specifications. Counting from the timing cover end of the engine, the valve sequence is: tnlet 2-4-5-7 Exhaust 7-3-6-$ 11 Where clearances are incorrect, the particular shim will have to be changed. To remove the shim, turn the crankshaft until the high point of the cam Is pointing directly upward. The cam follower will now have to be depressed so that the shim can be extracted. Special tools are available from your Fiat dealer to do the job, otherwise you will have to make up a forked (ever to locate on the rim of the cam follower. This must allow room for the shim to be prised out by means of the cut-outs provided in the cam follower rim {see illustration). 12 Once the shim is extracted, establish its thickness and change It for a thicker or thinner one to bring the previously recorded

will allow the wheel cylinders to be checked, and the condition of the brake drum itself to be fully examined (see Chapter 9). 6 Refit the lubber plugs then lower the car to the ground.
30 Timing belt renewal
Refer to Chapter 2A or 2B. Note: Although the norma/ interval for timing belt renewal is 70 000 miles (105 000 km), it is strongly recommended that the interval Is reduced on vehicles which are subjected to intensive use. ie, mainly short journeys or a lot of stop-start driving. The actual belt renewal interval is therefore very much up to the individuaf owner. That being said, it is highly recommended to err on the side of safety, and

joint has not been disturbed for some time, if will bo necessary to gently manipulate the hose to break the joint. Do not use excessive force, or the radiator stub could be damaged. Allow the coolant to drain Into the container. 3 Certain models are fitted with cooling system bleed plugs, which should be opened to aid the draining process and help prevent airlocks. These are located on the top right hand edge of the radiator, on the heater Inlet hose and additionally, on 16-valve engines, on the heater outlet hose (see illustrations). If the coolant has been drained for a reason other than renewal, then provided It is ciean and less than two years old, it can be re-used, though this is not recommended. 4 Once ail the coofant has drained, reconnect the hose to the radiator and secure it in position with the retaining clip.
Cooling system flushing 5 If coolant renewal has been neglected, or If the antifreeze mixture has become diluted, then in time, Ihe cooling system may gradually lose efficiency, as the coolant passages become restricted due to rust, scale deposits, and other sediment. The cooling system efficiency can be restored by flushing the system clean. 6 The radiator should be flushed Independently of the engine, to avoid contamination. Radiator flushing 7 To flush the radiator disconnect the top and bottom hoses and any other relevant hoses from the radiator, with reference to Chapter 3. 8 Insert a garden hose into the radiator top inlet. Direct a flow of clean v/ater through the radiator, and continue flushing until clean water emerges from the radiator bottom outlet. 9 If after a reasonable period, the water still does not run clear, the radiator can be flushed wilh a good propnetary cooling system
cleaning agent. It is important that their manufacturer's Instructions are followed carefully. If the contamination is particularly bad, insert the hose in the radiator bottom outlet, and reverse-flush the radiator. Engine flushing 10 To flush the engine, remove the thermostat as described In Chapter 3 then temporarily refit the thermostat cover. 11 With the top and bottom hoses disconnected from the radiator, insert a garden hose into the radiator top hose. Direct a clean flow of water through the engine, and continue flushing until clean water emerges from the radiator bottom hose. 12 On complotion of flushing, refit the thermostat and reconnect the hoses with reference to Chapter 3,
Cooling system filling 13 Before attempting to fill the cooling system, make sure that all hoses and clips are in good condition, and that the clips are tight. Note that an antifreezo mixture must be used all year round, to prevent corrosion of the engine components (see below). 14 Remove the expansion tank filler cap. and fill the system by slowly pouring the coolant Into the oxpansion lank to prevent airlocks from forming. Ensure that all bleed plugs/screws are open. 15 If the coolant Is being renewed, begin by pouring in a couple of litres of v/ater, followed by the correct quantity of antifreeze, then top-up with more water. 16 Once the level in the expansion tank starts to rise, squeeze the radiator top and bottom hoses to help expel any trapped air In the system. Once all the air is expelled, top-up the coolant level to the MAX mark and refit the expansion tank cap. Close all bleed plugs. Continue the filling procedure as follows according to engine type.
1108 cc and 1242 cc (8-vaive) engines 17 Start the engine and run it until tt reaches normal operating temperature, then stop the engine and allow it to cool. 18 Chock for teaks, particularly around disturbed components. Check the coolant level in the expansion tank, and top-up H necessary. Note that the system must be coW before an accurate level Is indicated in the oxpansion tank. If the expansion tank cap is removed while the engine Is still warm, cover Ihe cap with a thick cloth, and unscrew the cap slowly to gradually relieve the system pressure (a hissing sound will normally be heard). Wall until any pressure remaining In the system is released, then continue to turn the cap until It can be removed. 1242 cc (16-valve) engines 19 Remove the expansion tank filler cap. start the engine and run it at Idling speed for two to three minutes. Allow the engine to continue running until the electric cooling fan operates, but during this time, briefly in-crease the engine speed to 2000 to 3000 rpm every 30 seconds. Maintain the coolant level in the expansion tank to the MAX mark during tliis procedure, adding more coolant as necessary. 20 On models without air conditfoning, wilh the engine still idling, carefully unscrew the bleed plug on the top of the radiator. Increase the engine speed until fluid emerges from the bleed plug, then close the plug and return the engine to idle.

Maintenance procedures
1 Introduction
This Chapter Is designed to help the home mechanic maintain his/her vehicle for safety, economy, long life and peak performance. The Chapter contains a master maintenance schedule, and Sections dealing specifically with each task in the schedule. Visual checks, adjustments, component renewal and other helpful items are included. Refer to the accompanying illustrations of the engine compartment and the underside of the vohicle for the locations of the various components. Servicing your vehicle in accordance with ihe mileage/time maintenance schedule and the following Sections will provide a planned maintenance programme, which should result in a long and reliable service life. This is a comprehensive plan, so maintaining some items but not others at the specified service internals, will not produce the same results. As you service your vehicle, you will ctecover that many of the procedures can. and should, be grouped together, because of the particular procedure being performed, or because of the proximity of two otherwise-unrelated components to one another. For example, if the vehicle is raised for any reason, the exhaust can be inspected at the same time as the suspension and steering components. The first step in this maintenance programme is to prepare yoursetf before the
actual work begins. Read through all the Sections relevant to the work to be carried out. then make a list and gather all the parts and tools required. If a problem is encountered, seek advice from a parts specialist, or a dealer service department.
2 Regular maintenance
1 If, from the time Ihe vehicle is new, the routine maintenance schedule is followed closely, and frequent checks are made of fluid levels and high-wear Items, as suggested throughout this manual, the engine wifl be kept in relatively good running condition, and the need for additional work will be minimised. 2 It is possible that there will be times when the engine is running poorly due to the lack of regular maintenance. This is even more likely if a used vehicle, which has not received regular and frequent maintenance checks, is purchased, in such cases, additions! work may need to be carried out, outside of the regular maintenance intervals. 3 If engine wear is suspected, a compression test {refer to Chapter 2C} will provide valuable information regarding the overall performance of the main internal components. Such a test can be used as a basis to decide on the extent of the work to be carried out. If, for example, a compression test indicates serious Internal engine wear, conventional maintenance as
described in this Chapter will not greatly improve the performance of the engine, and may prove a wa3te of time and money, unless extensive overhaul work Is carried out first. 4 The following series of operations are those usually required to Improve the performance of a generally poor-running engine:
Primary operations a,I Clean, Inspect and test the battery (See Weekly checks). b) Check all the engine-related fluids (See Weekly checks). c) Drain the water from the fuel filter (Section 4) d) Check the condition and tension of the auxiliary dnvebeft(s) (Section 16). e) Check the condition of the air fitter, and renew if necessary (Section 13). f) Check the condition of all hoses, and check for fluid leaks (Section 8). g) Check the engine idle speed setting {Section 11). h) Check the exhaust gas emissions (Section 25). 5 If the above operations do not prove fully effective, carry out the following secondary operations:
Secondary operations All items listed under Pnmary operations, plus the following: a) Check the charging system (Chapter 5A, Section 4). b) Renew the fuel filter (Section 12) and check the fuel system (see Chapter 4Q.

Every 5000 miles (7500 km) or 6 months
3 Engine oil and filter renewal it-
1 Frequent oil and filter changes are the most important preventative maintenance procedures which can be undertaken by the OlY owner. As engine oil ages, if becomes diluted and contaminated, which leads lo premature engine wear. 2 Befote starting this procedure, gather ail the necessary tools and materials. Also make sure that you have plenty of clean rags and newspapers handy, to mop up any splits. Ideally, the engine oil should be warm, as it will drain better, and more built-up sludge will be removed with it. Take care, however, not to touch the exhaust or any other hot parts of the engine when working under the vehicle. To avoid any possibility of scalding, and to protect yourself from possible skin irritants and other harmful contaminants in used engine oils, it is advisable to wear gloves when carrying out this woik. Access to the underside of the vehicle will be greatly improved if it can be raised on a lilt, driven onto ramps, or jacked up and supported on axle stands {see Jacking and vehicle support). Whichever method Is chosen, make sure that the vehicle remains level, or If it is at an angle, that Ihe drain plug is at the lowest point. 3 Slacken the drain plug about half a turn using a 12 mm Allen key (see Illustration) Position the draining container under the drain plug, then remove the plug completely (see Haynes Hint), 4 Allow some time for the oid oil to dram, noting that it may be necessary to reposition the container as the oil (tow slows to a trickle. 5 After all the oil has drained, wipe off the drain plug wilh a clean rag, then clean the area around the drain plug opening and refit the plug. Tighten the ptug securely. 6 If the filter is also to be renewed, move the container Into position under the oil filter, which Is located on the front right-hand side of the engine. 7 Using an oil filter removal tool if necessary, slacken the filter initially, then unscrew It by hand the rest of the way (see illustrations).
3.3 Using a 12 mm Allen key to loosen the engine oil drain plug
Empty the oil In (he old filter Into Ihe container. 8 Use a clean rag to remove all oil, dirt and sludge from the filter sealing area on the engine. Check the old lilter to make sure thai the rubber sealing ring has not stuck to the engine. If it has. carefully removo it. 9 Apply a light coating of clean engine oil to the sealing ring on the new filter, then screw it into position on the engine. Tighten the filter firmly by hand only • do not use any tools (see Illustration), 10 Remove Ihe old oil and all tools from under the vehicle then lower Ihe vehicle to the ground (If applicable). 11 Remove tho dipstick, then unscrew (he oil liiler cap from the cylinder head cover. Fill the engine, using Ihe correct grade and typo of oil (see Weekly checks). An oil can spout or funnel may help to reduce spillage Pour in half the specified quantity of oil first, then wait a few minutes for the oil to fall to the sump. Continue adding oil a smalt quantity at a time until Ihe level Is up to the MAX mark on the dipstick. Refit the filler cap. 12 Start the engine and run it for a tew minutes; check for leaks around the oil filter seal and the sump drain plug. Note that there may be a delay of a few seconds before the oil pressure warning light goes oul when the engine is first started, as the oil circulates through the engine oil galleries and the new oil filter before the pressure builds up.
Keep the drain plug pressed Into the sump while unscrewing It by hand the lost couple of turns. As the plug releases, move It away sharpty so that the stream of oil issuing from the sump runs Into the container, not up your sieeve.
13 Switoh off the engine, and wait a few minutes for Ihe oil to settle in the sump once mora. With the new oil circulated and the fitter completely full, recheck the level on Ihe dipstick, and add more oil as necessary. 14 Dispose ot the used engine oil safely, wilh reference lo General repair pioceduros In Ihe reference Sections of this manual.
4 Fuel filter water draining ^
1 A water drain screw is provided at the base of the fuel filter. 2 Position a suitable container under ihe fuel filter, Loosen Ihe bleed screw on the lop ol the filter, and open the drain screw at the base of tne filter by turning it anti-clockwise Allow fuel and water to drain until fuel, free from water, emerges from tho drain screw outlet. Close tne drain and bleed screws and tighten them securely 3 Dispose of the drained fuel safely. 4 Start tho onglno. II difficulty is experienced, Weed the fuel system (see Chapter 4C).

15 Steering and §S> suspension check ^
Front suspension and steering check 1 Raise the front of the vehicle, and securely support it on axle stands (see Jacking and vehicle support). 2 Visually Inspect the balljoint dust covers and the steering rack-and-pinion gaiters for splits, chafing or deterioration. Any wear of Ihese components will cause loss of lubricant, together with dirt and water entry, resulting in rapid deterioration of the balljoints or steering gear. 3 On vehicles with power steering, check the fluid hoses for chafing or deterioration, and the pipe and hose unions for fluid leaks. Also check for signs of fluid leakage under pressure from the steering gear rubber gaiters, which would indicate failed fluid seals within the steenng gear. 4 Grasp the roadwheel at the 12 o'clock and 6 o'clock positions, and try to rock it (see illustration). Very slight free play may be felt, but if the movement is appreciable, further investigation is necessary to determine the

12.4b Showing the drain screw components on the bottom of the fuel filter source. Continue rocking the wheel while an assistant depresses the footbrake. If the movement Is now eliminated or significantly reduced, it is likely that the hub bearings are at fault. If the free ptay is still evident with the footbrake depressed, then there Is wear In the suspension joints or mountings. 5 Now grasp the wheel at the 9 o'clock and 3 o'clock positions, and try to rock it as before. Any movement felt now may again be caused by wear in the hub bearings or the steering track-rod balljoints. If the inner or outer balljoint Is worn, the visual movemont will be obvious. 6 Using a large screwdriver or flat bar. check for wear in the suspension mounting bushes by levering between the relevant suspension component and its attachment point. Some movement is to be expected as the mountings are made of rubber, but excessive wear should be obvious. Also check the condition of any visible rubber bushes, looking for splits, cracks or contamination of the rubber.

7 With the car standing on Its wheels, have an assistant turn the steering wheel back and forth about an eighth of a turn each way. There should be very hide. If any, lost movement between the steering wheel and roadwheels. If this is not the case, closely observe the joints and mountings previously described, but in addition, check the steering column universal joints for wear, and the rack-and-plnion steering gear itself.
Suspension strut/ shock absorber check 8 Check for any signs of fluid leakage around the suspension strut/shock absorber body, or from the rubber gaiter around the piston rod, Should any fluid be noticed, the suspension strut/shock absorber is defective Internally, and should be renewed. Note: Suspension struts/shock absorbers should always be renewed in pairs on the same axle.
9 The efficiency of the suspension strut/shock] absorber may be checked by bouncing 0*1 vehicle at each comer. Generally speaking. th»| body will return to its normal position and 8top| after being depressed. If It rises and returns cn| a rebound, the suspension strut/shocH absorber is probably suspect. Examine also* the suspension strut/shock absorber uppeij and lower mountings for any signs of wear.

Note: Fiat specify the use of a spec/a/ toot to correctly set the drivebelt fens/on. if access to this equipment cannot be obtained, an approximate setting can be achieved using the method described beiow. If the method described Is used, the tension should be checked using the spec/a/ too! at the earliest possible opportunity. 1 Depending on equipment fitted, one, two or three auxiliary drivebeits may be fitted. The alternator, power steering pump and air conditioning compressor, as applicable, are each driven by an individual drivebelt. Checking 2 Disconnect the battery negative terminal (refer to Disconnecting the battery In the Reference Section of this manual). 3 Firmly apply the handbrake, then Jack up the Iront of the car and support it securely on exie stands (see Jacking and vehicle support). 4 Remove the right-hand wheel. 5 Remove the Inner cover(s) from under the right-hand wheelarch for access to the right-hand side of the engine. 6 Using a socket on the crankshaft sprocket bolt, rotate the crankshaft so that the full length of the auxiliary drivebelt(s) can be examined. Look for cracks, splitting and fraying on the surface of the belt: check also for signs of glazing (shiny patches) and

Renewal
Alternator drivebelt 8 On models with air conditioning, remove the compressor drivebelt as described below, 9 Unclip and remove the upper timing belt cover, then unbolt end remove the lower timing belt cover. 10 Loosen the pivot bolt and adjustment lockbolt then unscrew the adjustment bolt to move the alternator towards the engine so that the drivebelt may be slipped off the alternator, crankshaft, and, on models with air con-ditioning, the Idler pulley (see Illustrations), 11 When renewing a drivebelt. ensure that the correct type is used. Fit the belt around the pulleys then tighten the adjustment bolt to take up any slsck In the belt. Adjust the tension correctly as described below. Power steering pump drivebelt
12 Remove the alternator drivebelt as described previously. 13 Slacken the bolts securing the power steering pump to the mounting bracket. 14 Slacken the adjusting bolt locknut and turn the adjusting bolt until ail the tension Is removed from the dnvebelt. 15 Undo the bolts and remove the pulley guard from the power steering pump then slip the drivebelt off the pulleys,

Tensioning 20 Correct tensioning of the belt will ensure that it has a long life. A belt which is too slack will slip and perhaps squeal. Beware, however, of overiightenlng. as this can cause wear in the alternator, power steering pump or air conditioning compressor bearings. Note: Flat recommend use of their spec's/ tensioning tool however the following procedure will set the tension correctly. 21 The belt(s) should be tensioned so that, under firm thumb pressure, there is approximately 5.0 mm of free movement at the mid-point between the pulleys. To adjust, tighten or loosen the relevant adjustment bolt until the tension is correct. Fully tighten the pivot and adjustment lockbotts. Repeat this procedure for any remaining drivebeits removed for access. 22 Refit the lower timing belt cover end tighten the mounting bolts. 23 Refit the upper timing belt cover and secure with the clips. 24 Refit the inner cover and wheel, lower the vehicle to the ground, then reconnect the battery negative terminal.

Warning: Wait until the engine is coid before starting this procedure. Do not allow anti-fnue to come in contact with your skin, or with the painted surfaces of the vehicle.
Rinse
off spills immediately with plenty of water. Never leave antifreeze lying around fh an open container, or in a puddle in the driveway or on the garage floor. Children

antifreeze can be fatal if ingested. 1 With the engine completely cold, cover the expansion tank cap with a wad of rag, and slowly turn the cap anti-clockwise to relieve the
pressure in the cooling system (a hissing sound will normally be heard). Wail until any pressure remaining in the system is released, then continue to turn the cap until it can be removed. 2 Position a suitable container beneath the radiator bottom hose connection, then release the retaining clip and ease the hose from the radiator stub (see Illustration), If the hose joint has not been disturbed for some time, it will be necessary to gently manipulate the hose to break the joint. Do not use excessive force, or the radiator stub could be damaged. Allow the coolant to drain into the container. 3 Certain models are fitted with cooling system bleed plugs, which should be opened to aid the draining process and help prevent airlocks. These are located on the heator Inlet hose and on the top right hand edge of the radiator (see Illustrations), ff the coolant has
been drained for a reason other than renewal, then provided It is clean and less than two years old, it can be re-used, though this is not recommended. 4 Once all the coolant has drained, reconnect the hose to the radiator and secure it in position with the retaining clip.
Cooling system flushing 5 If coolant renewal has been neglected, or if the antifreeze mixture has become diluted, then In time, the cooling system may gradually lose efficiency, as the coolant passages become restricted due to rust, scale deposits, and other sediment. The cooling system efficiency can be restored by flushing tho system clean. 6 The radiator should be (lushed independently of the engine, to avoid unnecessary contam-ination.
