How to Add Coolant to the Coolant Recovery Tank

If you have not found a problem yet, but the coolant level is not at or above the full cold mark, add a

50/50 mixture of clean, drinkable water and DEX-COOL®engine coolant at the coolant recovery tank. See Engine Coolant on page 5-24for more information.

{CAUTION:

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you would not get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL®coolant.

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.

When the coolant in the coolant recovery tank is at or above the full cold mark, start your vehicle.
