Checking the Coolant Level

The arrows in the illustrations indicate the positions of the MAX and MIN coolant level marks. Left: for 4- and 5-cylinder engines; right: for the 6-cylinder engine.

Regular checks
Do not rely solely on the coolant temperature/coolant level indicator. From time to time, check the coolant level in the expansion tank in the engine compartment:

The coolant level can only be measured accurately with the engine switched off.
The coolant level in the transparent expansion tank is clearly visible from outside, even with the cap closed. With a cold engine, the level should be between the marks.

With a warm engine, the level naturally rises slightly.
