Coolant Level

The coolant reservoir provides a quick visual method to check that the coolant level is adequate. With the engine off and cold, the engine coolant (antifreeze) level in the reservoir should be between the marks on the reservoir.

The radiator normally remains completely full, so there is no need to remove the radiator or coolant pressure cap unless checking the engine coolant freezing point or replacing the coolant. Inform service personnel of this. As long as engine operating temperature is satisfactory, the coolant reservoir only needs to be checked once a month.

When additional engine coolant is required to maintain the proper level, add only OAT coolant that meets the manufacturer's material standard MS.90032 to the coolant reservoir. Do not overfill.
