5.2 Check the thickness of the pad friction material through the hole on the front of the caliper should be removed and cleaned. The operation of the caliper can then
bIbo
be checked, and the condition of the brake disc itself can be fully examined on both sides. Refer to Chapter 9 for further Information. 4 If any pad's friction material is worn to the specified thickness or less, all four psds must tie renewed as a set. Refer to Chapter 9. 5 On completion refit the roadwheels and lower the car to the ground
6 Underbody sealant check
I
1 Jack up the front and rear of the car and support It securely on axle stands (see Jacking and vehicle support). Alternatively position the car over an inspection pit. 2 Check the underbody. wheel housings and side sills for rust and/or damage to the under-body sealant. If evident, repair as necessary.
7 Hose and fluid leak check ^
I
1 Visually Inspect the engine joint laces, gaskets and seals for any signs of water or oil leaks. Pay particular attention to the areas around the camshaft cover, cylinder head, oil (liter and sump joint faces. Bear in mind that.
A leak In the cooling system will usually show up as white or rust~coloured deposits on the area adjoining the leak
over a period of time, some very slight seepage from these areas is to be expected -what you are really looking for is any indication of a serious leak (see Haynes Hint). Should a leak be found, renew the offending gasket or oil seal by refemng to the appropriate Chapters in this manual. 2 Also check the security and condition of all the engine-related pipes and hoses. Ensure that all cable-ties or securing clips ore In place and In good condition, Clips which are broken or missing can lead to chafing of the hoses, pipes or wiring, which could cause more serious probioms In the luture. 3 Carefully check the radiator hoses and heater hoses along their entire length. Renew any hose which is cracked, swollen or deteriorated, Cracks will show up better if the hose is squeezed. Pay close attention to the hose clips that secure the hoses to the cooling system components. Hose clips can pinch and puncture hoses, resulting in cooling system leaks. 4 Inspect all 'he cooling system components {hoses. |olnt faces etc.) for leaks. A leak in the coolmg system will usually show up as white-or rust-coloured deposits on the area adjoining the leak. Where any problems of this nature are found on system components, renew the component or gaskel with reference to Chapter 3. 5 Where applicable, inspect the automatic transmission fluid cooler hoses for leaks or deterioration. 6 With the vehicle raised, inspect the fuel tank and filler neck for punctures, cracks and other damage. The connection between the filler neck and tank Is especially critical. Sometimes a rubber filler neck or connecting hose will leak due to loose retaining clamps or deten orated rubber. 7 Carefully check all rubber hoses and metal fuel lines leading away Irom the fuel tank. Check for loose connections, deteriorated hoses, crimped lines, and other damage. Pay particular attention to the vent pipes and hoses, which often loop up around the fitter neck and can become blocked or crimped. Follow the lines to the front of the vehicle, carefully inspecting them all the way. Renew damaged sections as necessary. 8 From within tne engine compartment,
check the security of all fuel hose attachments and pipe unions, and inspect the fuel hoses and vacuum hoses for kinks, chafing and deterioration. 9 Where applicable, check the condition of the power steering fluid hoses and pipes.
8 Exhaust system check fe
1 With the engine cold (at least an hour after the vehicle has been driven), check the complete exhaust system from the engine to the end of the tailpipe. The exhaust system is most easily checked with the vehicle raised on a hoist, or suitably supported on axle stands (see Jacking and vehicle support), so that the exhaust components are readily visible and accessible. 2 Check the exhaust pipes and connections for evidence of leaks, severe corrosion and damage. Make sure thai all brackets and mountings are in good condition, and that all relevant nuts and bolts are tight, Leakage at any of the Joints or in other parts of the system will usually show up as a black sooty stain in the vicinity of the leak. 3 Rattles and other noises can often bo traced to the exhaust system, especially the brackets and mountings. Try to move the pipes and silencers. If the components are able to come Into contact with the body or suspension parts, secure the system with new mountings Otherwise separate the joints {if possible) and twist the pipes as necessary to provide additional clearance.
9 Driveshaft gaiter check
9.1 Checking the condition of a driveshaft gaiter
1
1 With the vehicle raised and securely supported on stands (see Jacking and vehicle support), turn the steering onto full lock, then s'owly rotate the roadwheel. Inspect the condition of Ihe outer constant velocity (CV) joint rubber garters, squeezing the gaiters to open out the folds. Check for signs of cracking, splits or deterioration of the rubber, which may allow the grease to escape, and lead to water and grit entry into the joint. Also check the security and condition of the retaining clips. Repeat these checks on the Inner CV joints (see Illustration), If any damage or deterioration Is found, the gaiters should be renewed (see Chapter 8, Section 3). 2 At the same time, check the general condition of (he CV joints themselves by first holding (he driveshaft and attempting to rotate the wheel. Repeat this check by holding the inner joint and attempting to rotate the driveshaft. Any appreciable movement indicates wear in the joints. wear In the driveshaft splines, or a loose driveshaft retaining nut

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. No

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

clearance within specification. For example, if the measured valve clearance was 1.27 mm too great, a shim thicker by this amount will be required. Conversely, if the clearance was 1.27 mm too small, a shim thinner by this amount will be required. 13 Shims have their thickness (mm) engraved on them; although the engraved side should be fitted so as not to be visible, wear still occurs and often obliterates the number. In this case, measuring their thickness with a metric micrometer is the only method to establish their thickness (see illustration). t4 In practice, if several shims have to be changed, they can often be interchanged, so avoiding the necessity of having to buy more new shims than is necessary. 15 If more than two or three valve clearances are found to be incorrect, it will be more convenient to remove the camshaft for easier removal of the shims. 16 Where no clearance can be measured, even with the thinnest available shim in position, the valve will have to be removed and the end of its stem ground off squarely. This will reduce its overall length by the minimum amount to provide a clearance. This job should be entrusted to your dealer as it is important to keep the end of the valve stem square. 17 On completion, refit the camshaft cover and gasket, air cleaner and duct, and spark plugs. 18 lower the vehicle to the ground.

15.13 Shim thickness is marked on the tower face (here 4.20 mm) at the beginning of this manual, and follow them Implicitly. Petrol Is a highly-dangerous and volatile liquid, and the precautions necessary when handling it cannot be overstressed. Note: 1242 cc (8-vatve) engine mode's from 1998 onwards are equipped with a modified fuel system incorporating a fuel fitter integral with the fuel pump. On these engines fuel filter renewal is not required. 1 The fuel filter is situated underneath the rear of the vehicle, on the right-hand side of the fuel tank (see illustration). To gain access to the filter, chock the front wheels, then jack up the rear of the vehicle and support it on axle stands (see Jacking and vehicle support). 2 Unscrew the bolt securing the filter to its support bracket. 3 Noting the fitted position of the filter body, release the retaining clips and disconnect the fuel hoses from the filter. The correct position is indicated by an arrow marked on ihe filter body 4 Remove the filter from the vehicle. Dispose safely of the old filter; it will be highly flammable, and may explode if thrown on a fire. 5 Locate the new filter into position, ensuring that the arrow on the filter body is pointing in the direction of the fuel flow, as noted when removing the old filter. The flow direction can otherwise be determined by tracing the fuel hoses back along their length. 6 Connect the fuel hoses to the filter and lighten the clips, then locate it in the support bracket and tighten the mounting bolt.

Warning: Voltages produced by an electronic ignition system are considerably higher than those produced by conventional ignition systems. Extreme care must be taken when working on the system with the Ignition switched on. Persons with surgically-Implanted cardiac pacemaker devices should keep well clear of the ignition circuits, components and test oquipment. 1 The ignition system components should be checked for damage or deterioration as follows.
General component check 2 The spark plug (HT) leads should be checked whenever new spark plugs are fitted. 3 Pull the leads from the plugs by gripping
the end
fitting, not the lead, otherwise the lead connection may be fractured.
Ensure that the leads are i numbered before removing i them, to avoid confusion when refitting
4 Check Inside the end fitting for signs of corrosion, which will look like a white crusty powder. Push the end fitting back onto the spark plug, ensuring that it is a tight fit on the plug. if not, remove the lead again and use pliers to carefully crimp the metal connector inside the end fitting until it fits securely on the
end
of the spark plug. 5 Using a clean rag, wipe Ihe emlre length of the lead to remove any built-up dirt and grease. Once the lead is clean, check for bums, cracks and other damage. Do not bend the lead excessively, nor pull the lead lengthways - the conductor inside might break. 6 Disconnect the other end of the lead from the ignition coll. Again, pull only on the end fitting. Check for corrosion and a tight fit in the
same
manner as the spark plug end. Refit the bad securely on completion. 7 Check the remaining leads one at a time, in
ihe same
way. 8 if new spark plug (HT) leads are required, purchase a set for your specific car and engine. 9 Even with the ignition system In first-class condition, some engines may still occasionally experience poor starting attributable to damp ignition components.

1 Lubricate the hinges of the bonnet, doors and tailgate with a light general-purpose oil. Similarly, lubricate ail latches, locks and lock strikers. At the same time, check the security and operation of all the locks, adjusting them If necessary (see Chapter 11). 2 Lightly lubricate the bonnet release mechanism and cable with a suitable grease.
23 Headlight beam adjustment % & ^
1 Accurate adjustment of the headlight beam is only possible using optical beem-setting equipment, and this work should therefore be carried out by a Fiat dealer or service station with the necessary facilities. In an emergency, however, the following procedure will provide an acceptable light pattern. 2 Position the car on a level surface with tyres correctly inflated, approximately 10 metres in front of. and at right-angles to, a wall or garage door, 3 Draw a horizontal line on the wall or door at headlamp centre height. Draw a vertical line corresponding to the centre line of the car, then measure off a point either side of this, on the horizontal line, corresponding with the headlamp centres. 4 Switch on the main beam and check that the areas of maximum illumination coincide with the headlamp centre marfcs on Ihe wall, if not. turn the adjustment screw located on the upper inside edge of the headlight unit to adjust the beam laterally, and the adjustment screw located on the upper outside edge of the headlight unit to adjust the beam
vertically. On models with electric headlight adjustment, make sure that it is set at its basic setting before making the adjustment.
24 Road test
Instruments and electrical equipment 1 Check the operation of all Instruments and electrical equipment. 2 Make sure that all instruments read correctly, and switch on all electrical equipment in turn, to check that it functions properly.
Steering and suspension 3 Check for any abnormalities in the steering, suspension, handling or road feel. 4 Drive the vehicle, and check that there are no unusual vibrations or noises. 5 Check that the steering feels positive, with no excessive sloppiness, or roughness, and check for any suspension noises when cornering and driving over bumps.
Drivetrain 6 Check the performance of the engine, clutch (where applicable), transmission and driveshafts. 7 Listen for any unusual noises from the engine, clutch and gearbox/transmission. 8 Make sure that the engine runs smoothly when Idling, and that there Is no hesitation when accelerating. 9 Check that, where applicable, the clutch action Is smooth and progressive, that the drive is taken up smoothly, and that the pedal travel is not excessive. Also listen for any noises when the clutch pedal is depressed. 10 On manual gearbox models, check that all gears can be engaged smoothly without noise, and that the gear lever action is not abnormally vsgue or notchy. 11 On automatic transmission models, check that all Ihe gear positions can be selected with the vehicle at rest, if any problems are found, they should be referred to a Flat dealer. 12 Listen for a metallic clicking sound from the front of the vehicle, as the vehicle is driven slowly in a circle with the steering on full-lock. Carry out this check in both directions. If a clicking noise is heard, this Indicates wear in a drtveshaft joint, In which case renew the joint if necessary.
Check the braking system 13 Make sure that the vehicle does not pull to one side when braking, and that the wheels do not lock prematurely when braking hard. 14 Check that there is no vibration through the steering when braking. 15 Check that the handbrake operates correctly without excessive movement of the lever, and that It holds the vehicle stationary on a slope.
