The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING
The following instructions must be followed at all times when working on
■
the engine compartment » page
Never open the end cover of the coolant expansion reservoir while the
■
engine is still warm. The cooling system is pressurised -There is a risk of
scalding or injury from splashes of coolant!
To protect against the coolant splashing, cover the cap with a cloth when
■
opening.
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
■
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.

Refilling
The reservoir must always contain a small amount of coolant

Place a cloth over the cap of the coolant expansion reservoir and unscrew
the cap carefully.
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» fig. 162.
If the specified coolant is not available, then refilling only with distilled or puri-
fied water, and get a specialist garage to correct the water-coolant additive
mix as soon as possible.
CAUTION
With an empty expansion tank top up coolant. The system could aerate -

There is a risk of engine damage!
seek assistance from a specialist garage.
Do not fill the coolant above the mark
■
heated, be expelled from the cooling system - There is a risk of damage to the
engine parts.
If it is not possible to add coolant,stop driving! Switch off the engine and
■
seek assistance from a specialist garage.
A coolant additive which does not correspond to the correct specification can
■
reduce the anti-corrosion effect of the cooling system -There is a risk of dam-
age to the cooling system and the engine.
If distilled (purified) water has been used to top up, the coolant should be re-
■
placed by a specialist garage - There is a risk of engine damage.
A loss of coolant indicates leaks in the cooling system -There is a risk of en-
■
gine damage. Top up with coolant and then seek assistance from a specialist
garage.
