Adding Additional Coolant

ADDING ADDITIONAL COOLANT

The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. In order to maintain the required protection for these components and cooling system performance, only use the appropriate fluid when servicing the vehicle.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Do not remove the radiator cap to add antifreeze mixture to the system. When adding antifreeze mixture to maintain the correct level, do so only at the reserve/overflow bottle. Remove the radiator cap only for testing or when refilling the system after service. Removing the cap unnecessarily can cause loss of antifreeze mixture and allow air to enter the system, which produces corrosion.

WARNING: Do not remove or loosen the radiator cap with the cooling system hot and under pressure. Serious burns from the coolant or high pressure steam can occur.
