Coolant
Introduction
The coolant helps to keep the engine temperature down, and consists of water
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 75.
■
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
medical 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.
