WARNING: Avoid excessive skin contact
with mineral oil. Mineral oils remove the
natural fats from the skin, leading to
dryness, irritation and dermatitis.
1.Position vehicle on ramp.
2.Apply handbrake and position chocks under
front and rear wheels.
3.Remove underbelly panel.
+ EXTERIOR FITTINGS, REPAIRS,
Panel - underbelly.
4.Connect TestBook/T4 to monitor gearbox fluid
temperature.
CAUTION: The gearbox fluid level must only
be checked when the temperature of the
fluid is between 35° and 45°. The reading
obtained will be incorrect if the fluid is
outside this temperature range.
5.Start engine, move selector lever from 'P'
through all gear positions, pausing in each gear
position for 2-3 seconds and return to 'P'
position.
6.Clean area around level plug.
7.With the engine still running, remove level plug
using a 5 mm Allen socket and allow any
excess fluid to drain off.
CAUTION: There are a number of similar
fixings/plugs on the underside of the
gearbox. It is imperative that the correct
plug is removed prior to checking the level.
Removing the wrong fixing/plug could
result in internal damage to the gearbox.
8.If no fluid loss is apparent when level plug is
removed:

KV6 – Petrol engines
Check
1.Check security of all fuel hoses, paying
particular attention to those running under the
vehicle. Check all hoses and pipes are correctly
routed and secured. Check for signs of leakage
or damage.
Brake Hoses and Pipes
Check
1.Visually check condition of all brake hoses.
Look for any sign of damage or chafing. Check
for any signs of fluid leakage.
2.Check brake pipes for signs of leakage or
corrosion. Pay particular attention to pipe
unions and joints. Ensure all pipes and hoses
are correctly routed and secured.
Check Exhaust System
Check
1.Visually check condition of exhaust system for
signs of damage. Extra care should be taken to
ensure the catalyst is in good condition and
shows no signs of damage. Check condition of
exhaust heat shields.
