Checking the cooling system for leaks
Coolants losses are mostly caused by leaks in the cooling system.
On a non-leaking cooling system, losses only occur when the coolant boils
and this then causes coolant to be pressed out of the cooling system at the
sealing cap on the expansion tank. The cause of this can be contamination
in the area of the radiator fins (see the chapter 8.2.3 Checking the radiator
fins for dirt accumulation, page 55).
