CLEANING
Cleaning the vehicle
Before the vehicle is cleaned, check for leaks in the engine, axles, gearbox, etc.
This is no longer possible after cleaning the vehicle and carrying out maintenance
work.
When a high-pressure cleaner is used, take special note of the following points:
- Make sure that the doors, windows and roof hatch are properly closed.
- Never spray directly on seals. There is a danger of them being forced open so
that water can penetrate or grease packed behind them is flushed away. This
may happen, for example, with the universal joint on the steering box. As a
result, the spider may seize so that the steering will jam.
- Do not spray directly onto steering ball joints.
- The power steering fluid reservoir is fitted with a vent. Water may enter the
reservoir via this vent, which will cause damage to the steering gear.
- When cleaning the radiator/intercooler, take care not to damage the fins.
- Do not direct the high-pressure cleaner/steam 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. Parts of the air-conditioning must not be cleaned with the aid of a
high-pressure/steam cleaner as this can cause damage to the seals.
- Make sure that no water can enter the differential and gearbox via the vents.
- Make sure that no water can enter via the reservoir bleed screws of the clutch,
brakes, trailing axle, etc.
