Notice: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mixture.

to settle and top off if the level drops.

Do not spill coolant on the accessory drive belts.

If a spill occurs, rinse the belt with fresh water.
