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.
