It is not permissible to top up large amounts of
coolant via the expansion tank. Filling via the ex

system which can lead to e.g. damage to the cool
-
ant pump shaft seal. If a large amount of coolant
needs to be added, follow the instructions in the
section
Filling coolant
.
Never fill a hot engine with a large amount of
cold coolant. There is a high risk of cracks form
-
ing in the cylinder block and cylinder heads
Do not start the engine until the correct coolant
level has been obtained. If the engine is started
with an insufficient coolant level, it can damage
the coolant pump shaft seal, which leads to cool
-
ant leakage.
