Checking the coolant level in the expansion tank
Checking the density of the coolant in the expansion tank
Warning: Never open the engine hood if you see steam coming out of the engine compartment or coolant leaking out – risk of getting burned! Wait until the steam or coolant stops leaking out.
The expansion tank of the engine cooling system is located in the engine compartment.
The coolant level can only be checked correctly when the engine is off.
The coolant level when the engine is cold should be between the min and max marks on the expansion tank; when the engine is warm, the level may also be slightly above the max mark (see figure Checking the coolant level in the expansion tank).
To check the density, you need to use a coolant hydrometer (see figure Checking the density of the coolant in the expansion tank).
