228 Checking and refilling levels
Opening the coolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒ .
Checking coolant level
– Look into the open coolant expansion tank and read off the
coolant level.
– If the level is below the "MIN" mark, top up with coolant.
Topping up coolant
– Only use new coolant liquid.
– Do not fill above the "MAX" mark.
Closing the coolant expansion tank
– Screw the cap on again tightly.
The position of the coolant expansion reservoir is shown in the correspond-
ing engine compartment illustration ⇒ p age 276.
Make sure that the coolant meets the required specifications ⇒ p age 227.
Do not use a different type of additive if additive G 12+ is not available. In
this case use only water and bring the coolant concentration back up to the
correct level as soon as possible by putting in the specified additive
⇒ p age 227.
Always top up with new coolant.
Do not fill above the "MAX" mark. Otherwise the excess coolant will be
forced out of the cooling system when the engine is hot.
The additive G 12+ (purple) may be mixed with G 12 (red) and also with G
11.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ p age 220.
● When the engine is warm or hot, the cooling system is pressurised!
Do not unscrew the cap on the expansion tank when the engine is hot.
This is a burn injury risk.
CAUTION
● When mixed with other additives the colour of G 12 will change to
brown. If this occurs you should have the coolant changed immediately.
Failure to do so will result in engine damage!
● If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large cool-
ant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage.
