INFORMATION JOINTS AND JOINT FACES
1.Always use correct gaskets where they are
specified.
2.Use jointing compound only when
recommended. Otherwise fit joints dry.
3.When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent it from entering oilways, pipes or blind
tapped holes.
4.Remove all traces of old jointing materials prior
to reassembly. Do not use a tool which could
damage joint faces.
5.Inspect joint faces for scratches or burrs and
remove with a fine file or oil stone; do not allow
removed material or dirt to enter tapped holes or
enclosed parts.
6.Blow out any pipes, channels or crevices with
compressed air, fit new 'O' rings or seals
displaced by air blast.FLEXIBLE HYDRAULIC PIPES, HOSES
1.Before removing any brake or power steering
hose, clean end fittings and area surrounding
them as thoroughly as possible.
2.Obtain appropriate plugs or caps before
detaching hose end fittings, so that ports can be
immediately covered to exclude dirt.
3.Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any hose found faulty.
4.When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is not
twisted before or during tightening of union nuts.
5.Containers for hydraulic fluid must be kept
absolutely clean.
6.Do not store brake fluid in an unsealed
container. It will absorb water, and fluid in this
condition would be dangerous to use due to a
lowering of its boiling point.
7.Do not allow brake fluid to be contaminated with
mineral oil, or use a container which has
previously contained mineral oil.
8.Do not re-use brake fluid bled from system.
9.Always use clean brake fluid to clean hydraulic
components.
10.Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
11.Absolute cleanliness must be observed with
hydraulic components at all times.
12.After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to
the brakes (engine running) and operates the
steering.

MAINTENANCE
CHECK/TOP UP COOLING SYSTEM
1.To prevent corrosion of aluminium alloy engine
parts it is imperative that cooling system is filled
with a solution of water and phosphate free
anti-freeze, winter or summer. Never fill or top up
with plain water.
WARNING: Do not remove filler cap when
engine is hot because cooling system is
pressurised and personal scalding could
result.
2.When removing filler cap, turn cap slowly
anti-clockwise, pause and allow all pressure to
escape.
3.Continue to turn until cap is removed.
4.When engine is cold expansion tank coolant
should be level with top of indicator post, visible
inside tank through filler hole.
5.If necessary, top up cooling system with
premixed coolant. Use soft water whenever
possible, if local water supply is hard, rainwater
should be used.
6.When replacing filler cap it is important that it is
tightened down fully. Failure to tighten filler cap
properly may result in water loss, with possible
damage to engine
The cooling system should be drained and flushed at
2 year intervals or at onset of second winter. Refer to
Coolant Requirements.
See COOLING SYSTEM,
Adjustment, Coolant RequirementsCHECK/ TOP UP POWER STEERING FLUID
RESERVOIR
1.Remove fluid reservoir cap. Check that fluid is
up to high mark on dipstick.
CHECK/ TOP UP CLUTCH AND BRAKE FLUID
RESERVOIRS
CAUTION: Brake fluid can damage
paintwork. If spillage occurs, wash
affected area IMMEDIATELY with a large
quantity of water.
CHECK/TOP UP WASHER RESERVOIR
Top up washer reservoir to within 25 mm of filler neck.
Use a screen washer solvent/anti-freeze solution to
assist removing mud, flies and road film and protect
against freezing.

CLEAN BATTERY CONNECTIONS
NOTE: Some 96 models are fitted with
battery backed-up sounder
See
ELECTRICAL, Repair, Battery
Remove battery terminals, clean and coat with
petroleum jelly.
A low maintenance battery is installed in vehicle.
Dependent upon climate conditions electrolyte levels
should be checked as follows:
Temperate climates every three years.
Hot climates every year.
RENEW CAMSHAFT DRIVE BELT - Tdi
Renew camshaft drive belt.See ENGINE, Repair,
Camshaft Drive Belt and Gears
The engine timing gears are driven by a flexible
rubber belt which must be renewed at intervals
determined by the severity of operating conditions.
In reasonable, temperate climate operation, renew the
belt every 120,000 km (72,000 miles) or every 6 years
whichever occurs earlier.
In adverse operating conditions such as work in dusty
atmospheres, high ambient temperatures and desert
and tropical zones, renew the belt every 60,000 km
(36,000 miles) or every 3 years whichever occurs
earlier.
CAUTION: If the drive belt is not renewed
at the correct interval, it could fail,
resulting in serious damage.
RENEW CAMSHAFT DRIVE BELT - Mpi
Renew every 160,000 km (96,000 miles) or every 6
years. In adverse conditions every 80,000 km (48,000
miles).

Ball joints are lubricated for their normal life during
manufacture and require no further lubrication. This
applies ONLY if rubber boot has not been dislodged
or damaged. Joints should be checked at specified
mileage 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.
