Always reduce the engine speed to idle before disconnecting the jump leads.
Before removing the jump leads, switch on the heater blower (high) or the heated rear screen, to reduce the voltage peak
when the leads are removed.
Always disconnect the jump leads in the reverse order to the connecting sequence and take great care not to short the ends of
the leads.
Do not rely on the generator to restore a discharged battery. For a generator to recharge a battery, it would take in excess of 8
hours continuous driving with no additional loads placed on the battery.
Component Cleaning
To prevent ingress of dirt, accumulations of loose dirt and greasy deposits should be removed before disconnecting or
dismantling components or assemblies.
Components should be thoroughly cleaned before inspection prior to reassembly.
Cleaning Methods:
Dry Cleaning
Removal of loose dirt with soft or wire brushes
Scraping dirt off with a piece of metal or wood
Wiping off with a rag
CAUTION: Compressed air is sometimes wet so use with caution, especially on hydraulic systems.
Blowing dirt off with compressed air (Eye protection should be worn when using this method)
Removal of dry dust using vacuum equipment. This method should always be used to remove friction lining material
dust (asbestos particles)
Steam Cleaning
Calibration of Essential Measuring Equipment
WARNING: Failure to comply may result in personal injury or damage to components.
It is of fundamental importance that certain essential equipment e.g. torque wrenches, multimeters, exhaust gas analysers,
rolling roads etc., are regularly calibrated in accordance with the manufacturers instructions.
Use of Control Modules
Control modules may only be used on the vehicle to which they were originally installed. Do not attempt to use or test a
control module on any other vehicle.
Functional Test
On completion of a maintenance procedure, a thorough test should be carried out, to ensure the relevant vehicle systems are
working correctly.
Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oil ways, exposed
by component removal, with tapered hardwood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a separate container for each component and its associated parts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the materials
within the component. Clean the bench and obtain marking materials, labels, containers and locking wire before dismantling a
component.
Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic systems
are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems.
Clean all tapped holes, crevices, oil ways and fluid passages with compressed air.
WARNING: Do not permit compressed air to enter an open wound. Always use eye protection when using compressed air.
Make sure that any O-rings used for sealing are correctly reinstalled or renewed if disturbed. Mark mating parts to make sure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of causing
distortion or the initiation of cracks, which could occur if a center punch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed for reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not discard a part which is due for renewal until it has been compared with the new part, to make sure

Do not empty fuel while working in a workshop or a pit
Ensure that working area is well ventilated
Ensure that any work on the fuel system is only carried out by experienced and well qualified maintenance personnel
Ensure that fume extraction equipment is used where appropriate
Fume extraction equipment must be in operation when solvents are used e.g. Trichloroethane, white spirit, sbp3,
methylene chloride, perchlorethylene. Do not smoke in the vicinity of volatile degreasing agents.
Whenever possible, use a ramp or pit whilst working beneath a vehicle, in preference to jacking. Position chocks at the wheels
as well as applying the parking brake. Never rely on a jack alone to support a vehicle. Use axle stands, or blocks carefully
placed at the jacking points, to provide a rigid location. Check that any lifting equipment used has adequate capacity and is
fully serviceable. Ensure that a suitable form of fire extinguisher is conveniently located. When using electrical tools and
equipment, inspect the power lead for damage and check that it is properly earthed. Disconnect the earth (grounded) terminal
of the vehicle battery. Do not disconnect any pipes of the air conditioning refrigeration system unless you are trained and
instructed to do so. A refrigerant is used which can cause blindness if allowed to come into contact with the eyes. Ensure that
adequate ventilation is provided when volatile degreasing agents are being used.
Adhere strictly to handling and safety instructions given on containers and labels. Keep oils and solvents away from naked
flames and other sources of ignition. Do not apply heat in an attempt to free seized nuts or fittings; as well as causing
damage to protective coatings, there is a risk of damage from stray heat to electronic equipment and brake lines. Do not leave
tools, equipment, spilt oil etc. around the work area. Wear protective overalls and use barrier cream when necessary.
Environmental Protection
In some countries it is illegal to pour used oil onto the ground, down sewers or drains, or into water courses. The burning of
used engine oil in small space heaters or boilers is not recommended unless emission control equipment is installed. Dispose
of used oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation
trade. If in doubt, contact the Local Authority for advice on disposal facilities.

General Information - Standard Workshop Practices
Description and Operation
Protecting the Vehicle Published: 04-Jul-2014
Always install covers to protect the fenders before commencing work in the engine compartment. Always install the interior
protection kit, wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic
fluid, antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use polythene
sheets in the luggage compartment to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or installing caps.
Vehicle in Workshop
When working on a vehicle in the workshop always make sure that:
The parking brake is applied or the wheels are securely chocked to prevent the vehicle moving forwards or backwards
If the engine is to be run, there is adequate ventilation, or an extraction hose to remove exhaust fumes is installed
There is adequate room to jack up the vehicle and remove the wheels, if necessary
Fender covers are always installed if any work is to be carried out in the engine compartment
The battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle is jacked up
CAUTION: When electric arc welding on a vehicle, always disconnect the generator wiring to prevent the possibility of a
surge of current causing damage to the internal components of the generator.
If using welding equipment on the vehicle, ensure a suitable fire extinguisher is readily available.
Screw Threads
Damaged nuts, bolts and screws must always be discarded. Attempting to recut or repair damaged threads with a tap
or die impairs the strength and fit of the threads and is not recommended.
NOTES:
During certain repair operations, it may be necessary to remove traces of thread locking agents using a tap. Where this
is necessary, the instruction to do so will appear in the relevant operation and it is essential that a tap of the correct size and
thread is used.
New Taptite bolts when used cut their own threads on the first application.
Some bolts are coated with a thread locking agent and unless stated otherwise, they must not be reused. New bolts
having the same part number as the original must always be installed. When nuts or bolts are to be discarded, the
repair operation and relevant torque chart will include an instruction to that effect. Do not use proprietary thread
locking agents as they may not meet the specification required. See also Encapsulated ('Patched') Bolts and Screws.
Always make sure that replacement nuts and bolts are at least equal in strength to those that they are replacing.
Castellated nuts must not be loosened to accept a split pin except in recommended cases when this forms part of an
adjustment.
Do not allow oil or grease to enter blind holes, the hydraulic action resulting from tightening the bolt or stud can split
the housing and also give a false torque reading.
Always tighten a nut, bolt or screw to the specified torque figure, damaged or corroded threads can give a false torque
reading.
Nut and bolt loosening and tightening sequences, where given, must ALWAYS be followed. Distortion of components or
faulty sealing of joints will result if the sequences are not followed. Where an instruction is given to tighten in stages,
these stages must be adhered to; do not attempt to combine stages particularly where certain stages involve
tightening by degrees.
To check or re-tighten a fixing to a specified torque, first loosen a quarter of a turn, then retighten to the specified
torque figure.
Unless instructed otherwise, do not lubricate bolt or nut threads prior to installing.
Where it is stated that bolts and screws may be reused, the following procedures must be carried out:
Check that threads are undamaged.
Remove all traces of locking agent from the threads.
CAUTION: DO NOT use a wire brush; take care that threads are not damaged.
Make sure that threads are clean and free from oil or grease.
Apply the specified locking agent to the bolt threads.

Component Tests
Engine Oil Leaks
NOTE: Before installing new gaskets or oil seals, make sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual inspection, carry out an Ultraviolet test:
Fluorescent Oil Additive Method
1. Clean the engine with a suitable cleaning fluid (brake cleaner).
2. Drain the engine oil and refill with recommended oil, premixed with Diesel Engine Oil Dye or equivalent. Use a minimum
14.8 ml (0.5 ounce) to a maximum 29.6 ml (1 ounce) of fluorescent additive to all engines. If oil is not premixed,
fluorescent additive must first be added to the crankcase.
3. Run engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using a 12 Volt Master UV
Diagnostic Inspection Kit or equivalent. A clear bright yellow or orange area will identify leak. For extremely small
leaks, several hours may be required for the leak to appear.
4. As necessary, pressurize the main oil gallery system to locate leaks due to incorrectly sealed, loose or cocked plugs. If
the flywheel bolts leak oil, look for sealer on the threads.
5. Repair all leaks as necessary.
Compression Test General Remarks
NOTES:
Removing fuses and disconnecting electrical components may cause the Engine Control Module (ECM) to log Diagnostic
Trouble Codes (DTCs). After the measurements have been carried out, DTCs should be cleared from memory by connecting to
the Manufacturer Approved Diagnostic System.
Only check the compression pressure with the valves set to the prescribed clearance (if this can be adjusted).
The compression pressure should be checked with the engine at normal operating temperature.
Check the Compression Pressure
WARNING: Move gear selector lever to 'P' position. Failure to follow this instruction may result in personal injury.
1. Remove the fuel pump relay.
2. Start the engine - the engine will start, run for a few seconds then stall.
3. Remove the spark plugs.
4. Install the compression tester.
5. Install an auxiliary starter switch in the starting circuit. With the ignition switch OFF, using the auxiliary starter switch,
crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number
of compression strokes required to obtain the highest reading.
6. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes.
7. Install the removed components in reverse order, observing the specified tightening torques.
8. Clear all DTCs from the ECM.
Interpretation of the Results
NOTE: Due to the possibility of loose carbon that has become trapped between the valve face and seat effecting the
pressure readings, when carrying out a compression test and cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required.
The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75% of the
highest reading.
If the cylinder pressures are found to be low, carry out a leakdown test to determine the location of the fault (if any leakback
can be heard through the engine breather system suspect the piston rings, if any leakback can be heard through the inlet
system suspect the inlet valve or seat, if any leakback can be heard through the exhaust manifold suspect the exhaust valve
or seat. If the measurements for two cylinders next to each other are both too low then it is very likely that the cylinder head
gasket between them is burnt through. This can also be recognized by traces of engine oil in the coolant and/or coolant in the

engine oil).
Oil Consumption Test
The amount of oil an engine uses will vary with the way the vehicle is driven in addition to normal engine-to-engine variation.
This is especially true during the first 16,100 km (10,000 miles) when a new engine is being broken in or until certain internal
components become conditioned. Vehicles used in heavy-duty operation may use more oil. The following are examples of
heavy-duty operation:
Trailer towing applications
Severe loading applications
Sustained high speed operation
Engines need oil to lubricate the following internal components:
Cylinder block cylinder walls
Pistons and piston rings
Intake and exhaust valve stems
Intake and exhaust valve guides
All internal engine components
When the pistons move downward, a thin film of oil is left on the cylinder walls. As the vehicle is operated, some oil is also
drawn into the combustion chambers past the intake and exhaust valve stem seals and burned.
The following are examples of conditions that can affect oil consumption rates:
Engine size
Operator driving habits
Ambient temperatures
Quality and viscosity of oil
Engine is being run in an overfilled condition (check the oil level at least five minutes after a hot shutdown with the
vehicle parked on a level surface. The oil level should not be above the top of the cross-hatched area and the letter "F"
in FULL).
Operation under varying conditions can frequently be misleading. A vehicle that has been run for several thousand miles on
short trips or in below-freezing ambient temperatures may have consumed a "normal" amount of oil. However, when checking
the engine oil level, it may measure up to the full mark on the oil level indicator due to dilution (condensation and fuel) in the
engine crankcase. The vehicle then might be driven at high speeds on the highway where the condensation and fuel boil off.
The next time the engine oil is checked it may appear that a liter of oil was used in about 160 km (100 miles). Oil
consumption rate is about one liter per 2,400 km (1,500 miles).
Make sure the selected engine oil meets Jaguar specification and the recommended API performance category "SG" and SAE
viscosity grade as shown in the vehicle Owner's Guide. It is also important that the engine oil is changed at the intervals
specified for the typical operating conditions.
The following diagnostic procedure is used to determine the source of excessive oil consumption.
NOTE: Oil use is normally greater during the first 16,100 km (10,000 miles) of service. As mileage increases, oil use
decreases. High speed driving, towing, high ambient temperature and other factors may result in greater oil use.
1. Define excessive consumption, such as the number of miles driven per liter of oil used. Also determine customers
driving habits, such as sustained high speed operation, towing, extended idle and other considerations.
2. Verify that the engine has no external oil leaks as described under Engine Oil Leaks in this section.
3. Carry out an oil consumption test:
Run the engine to normal operating temperature. Switch engine OFF and allow oil to drain back for at least five
minutes .
With vehicle parked on level surface, check the engine oil level.
If required, add engine oil to set level exactly to the FULL mark.
Record the vehicle mileage.
Instruct the customer to return for a level check after driving the vehicle as usual for 1,610 km (1000 miles).
Check the oil level under the same conditions and at the same location as the initial check.
NOTE: If the oil consumption rate is unacceptable go to Step 4.
4. Check the Positive Crankcase Ventilation (PCV) system. Make sure the system is not plugged.
5. Check for plugged oil drain-back holes in the cylinder head and cylinder block.
6. If the condition still exists after carrying out the above tests go to step 9.
7. Carry out a cylinder compression test. Refer to the Compression Test procedure in this section. This can help determine
the source of oil consumption such as valves, piston rings or other areas.
8. Check valve guides for excessive guide clearance. Install new valve stem seals after verifying valve guide clearance.
9. Worn or damaged internal engine components can cause excessive oil consumption. Small deposits of oil on the tips of
the spark plugs can be a clue to internal oil consumption.

Operating Temperature Range -40 to 160 °C (-40 to 320 °F) Oil Level Check
For additional information, refer to Engine Oil Draining and Filling (303-01A, General Procedures).
For accuracy, oil level checks should be performed with the vehicle on level ground when the oil is hot. The vehicle needs to
stand for approximately 10 minutes, after the engine is switched off, to allow the oil to drain back into the sump pan and the
oil level to stabilize. The oil level system will not give a reading until the oil level has stabilized.
With the ignition on, the engine stopped and the transmission in P (park), repeatedly press the trip button on the end of the
LH multifunction switch until the oil level icon and applicable message are displayed in the fuel gage/trip computer area of the message center, as shown below:
Item Description A Oil level is between 50% and 100% of recommended level. No top-up required. B Oil level is between 12.5% and 50% percent of recommended level. Add 0.5 liter (0.53 US quart) of oil. C Oil level is between 0% and 12.5% of recommended level. Add 1 liter (1.06 US quarts) of oil. D Oil level is above maximum for safe operation. Reduce oil level to recommended level. E Oil level is below minimum for safe operation. Add 1.5 liters (1.59 US quarts) of oil, then recheck level. F Oil level is stabilizing. Wait 10 minutes and then recheck level. If this display is accompanied by the message ENGINE OIL LEVEL MONITOR SYSTEM FAULT, a fault with the oil level monitoring system is indicated. System Fault Warning
If there is a fault with the system, in addition to being displayed during an oil level check, the message ENGINE OIL LEVEL
MONITOR SYSTEM FAULT will be temporarily displayed when the ignition is first switched on.
