6.3 CLEANING THE VEHICLE

Before cleaning the vehicle, check the engine, 
axles, gearbox, etc. for of leaks. Having cleaned 
the vehicle, it will no longer be possible to check 
for leaks during the maintenance activities.

-

Make sure that doors, windows and roof 
hatch are securely closed during cleaning.

-

When cleaning the universal joint on the 
steering box, the spider seals may be forced 
open by the high-pressure jet of water, so 
that the grease behind them is flushed away. 
As a result, the spider may get stuck, so that 
the steering will "jam".

-

Do not spray directly onto steering ball joints.

-

There is a vent on the power steering fluid 
reservoir of the steering gear. Water may 
enter the power steering reservoir via this 
vent, which will cause damage to the 
steering gear.

-

When cleaning the radiator/intercooler, be 
careful not to damage the fins. 

-

Do not aim the high-pressure cleaner jet too 
long at the air conditioning system 
condenser. As a result of the high 
temperature, the pressure in the system will 
rise too high, which may cause damage to 
the system.

-

Make sure that no water can enter the 
differential and gearbox via the vents.

-

Make sure that no water can enter via the 
reservoir vents of clutch, brakes, trailing 
axle, etc.

-

The engine and engine compartment can be 
cleaned with a high-pressure cleaner. Make 
sure in this case not to spray directly onto 
seals, electrical components, such as the 
starting motor, alternator, etc.

-

When cleaning UPEC engines with a high-
pressure cleaner, do not aim it directly at the 
pump units. Water could penetrate into the 
protective covers via the vent holes. This 
could result in faults in the electrical 
connections of the pump units.

-

If an engine encapsulation is fitted, the 
encapsulation panels must be thoroughly 
cleaned after each maintenance job because 
of the risk of fire if the inside of the panels is 
dirty.

-

Do not aim the high-pressure cleaner jet at 
electrical connections such as connectors, 
lighting ducts, etc.

-

Make sure that during vehicle cleaning no 
water enters the air-intake system through 
the air intake of the flexible seals of the inlet.

-

Do not aim the high-pressure cleaner jet at 
the gear lever unit.

-

Do not aim the high-pressure cleaner jet 
directly at the drive shaft seals, such as the 
seals of the spider, intermediate bearing and 
sliding joint.

-

When the vehicle has been cleaned, it must 
be lubricated again with a grease gun or 
through the central lubrication system. This 
is important because it prevents the 
penetration of moisture and dirt at the 
various pivots.
