MAINTENANCE REV: 05/99 CHECK COOLING, INTERCOOLING AND HEATING
SYSTEMS
Check cooling, and heater systems for leaks and
pipes/hoses for security and condition. Refill or top up
as necessary.
CAUTION: It is important that the correct
procedure is followed when refilling or
topping up the cooling system to avoid
trapping air in the system.
WARNING: Do not remove caps and plugs
when engine is hot because cooling
system is pressurised and personal
scalding could result.
1.Remove plastic plugs from thermostat housing
and radiator.
2.Fill cooling system with correct concentration
and specification of anti-freeze.
See
LUBRICANTS, FLUIDS AND CAPACITIES,
Information, Recommended lubricants and
fluids
3.Fill from expansion tank until radiator is full, with
level in expansion tank the same as in radiator.
NOTE: Care should be taken to avoid
excess coolant spillage from radiator.
4.Fit plastic plug in radiator.
5.Add a further 1 litre (1.76 pints) of coolant to
expansion tank and allow to settle.
6.Refit expansion tank cap and thermostat
housing plug.
7.Run engine at idle speed for five minutes.
8.Switch off engine, check that expansion tank
coolant is level with top of indicator post and top
up as necessary.Check intercooler and turbo-charger system for air
leaks and pipes/hoses for security and condition.
All system hoses should be renewed at first signs of
deterioration.
VALVE CLEARANCES - CHECK/ADJUST

MAINTENANCE REV: 05/99 UNDER VEHICLE MAINTENANCE
NOTE: A chassis undertray may be fitted
on some vehicle derivatives to conform to
legal requirements. When under chassis
maintenance, or remove and refit procedures are
required, it may be necessary to remove the
undertray and/or integral access panels

CHASSIS AND BODY, Repair, Front undertray
or
See CHASSIS AND BODY, Repair, Rear undertray
RENEW ENGINE OIL AND FILTER
1.Ensure vehicle is level.
2.Run engine to warm oil, switch off ignition.
3.Disconnect battery.
4.Place suitable drain tray under sump drain plug.
5.Remove drain plug from sump and allow oil to
drain completely.
6.Fit new sealing washer, replace plug and tighten
to

OF BALL JOINTS AND DUST COVERSBall joints are lubricated for life during manufacture
and require no further lubrication unless the rubber
boot has been dislodged or damaged. All joints should
be checked at specified service intervals, but more
frequently if vehicle is used under arduous conditions.
1.Check for wear in joints by moving ball joint up
and down vigorously. If free movement is
apparent, fit a new joint assembly.

DRAIN AND CLEAN FUEL SEDIMENTER, IF
FITTED
The fuel sedimenter is located on a chassis side
member on the RH side of vehicle near rear wheel. It
increases the working life of the fuel filter by removing
larger droplets of water and other matter from fuel.
NOTE: On 110/130 models with a twin tank
fuel system, two sedimenters may be
fitted, one on each side of the vehicle
chassis.
1.Slacken drain plug and allow any water to drain
off.
