Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
148
Replenishing 149
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring.
The coolant additive in the coolant must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 155 on page 148.
WARNING
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 143.
■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■
Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.
■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage,
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.
■
Do not fill the coolant above the mark
A
.» Fig. 155 on page 148
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
