5. CLEANING

5.1 CLEANING THE ENGINE

Note:

It is advisable to clean the engine with a high-

pressure cleaner before starting maintenance or 

service operations. A clean environment makes 

your work easier, and enables you to notice any 

engine defects at an early stage.

Before cleaning the engine, check for any leaks.

If the engine is cleaned with a high-pressure 

cleaner, the high-pressure cleaner must be used 

with care. It is also important to observe the 

following points:

-

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 mechanism will jam.

-

There is an air bleed vent on the power 

steering fluid reservoir of the steering gear. 

Water may enter the reservoir through this 

air bleed vent, causing damage to the 

steering gear.

-

When cleaning the radiator/air cooler 

element, be careful not to damage the fins.

-

Do not direct 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 

become excessive, which may cause 

damage to the system.

-

Ensure that no water can enter the gearbox 

via the air bleed vents.

-

Make sure that no water can enter via the 

clutch reservoir bleed vents.

-

The engine compartment can be cleaned 

with a high-pressure cleaner. Never direct 

the jet of water towards electrical 

components.

-

When cleaning UPEC engines with a high-

pressure cleaner, do not aim the jet directly 

at the pump units. Water could penetrate into 

the protective covers via the bleed holes. 

This could result in failures in the electrical 

connections of the pump units.

-

Do not direct the jet of water at electrical 

connections such as connectors or lead-

throughs of the vehicle lighting system.

-

Ensure that no water can enter the air intake 

system via the air intake or its flexible seals.
