2
INFORMATION Propeller shaft Front
and RearNLGI - 2 Multi-purpose Lithium based GREASE
Lubrication nipples
(hubs, ball joints
etc.)
Seat slides
Door lock striker
Brake and clutch
reservoirsBrake fluids having a minimum boiling point of 260°C (500°F) and complying with
FMVSS 116 DOT4
Engine coolant Use Texaco XLC long life coolant. Use one part anti-freeze to one part water for
protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below 50% anti-freeze otherwise
damage to engine is liable to occur. Maximun concentration is 60%.
Battery lugs, Petroleum jelly.
Earthing surfacesNOTE: Do not use Silicone Grease
where paint has
been removed
Air Conditioning
System Refrigerant Use only refrigerant R134a
Compressor Oil ND-OIL 8
LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze, windscreen washer additives, lubricants and various adhesives.

MAINTENANCE AUXILIARY DRIVE BELT
Check
1.Check auxiliary drive belt for signs of splits,
fraying, oil contamination and wear.
NOTE: Any requirement to replace the
auxiliary drive belt should be advised to
the customer as this will incur additional
labour and/or material cost and should not be
carried out without the authorisation of the
customer.
Renew
1.Renew auxiliary drive belt.See ELECTRICAL,
Repair.
NOTE: Additional time is built into the
96,000/8 year service time to allow for
auxiliary drive belt renewal.PAS FLUID, CLUTCH FLUID AND SCREEN
WASHER LEVELS
PAS Fluid
1.Clean arear around PAS reservoir filler cap, and
remove cap.
2.Check fluid level in PAS reservoir.
3.Top-up if necessary to the correct level using
recommended fluid.See LUBRICANTS,
FLUIDS AND CAPACITIES, Information.
4.Fit filler cap.
