How to Add Coolant to the Coolant
Recovery Tank
{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.
If you have not found a problem yet, but the coolant
level is not at the cold fill line, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
®
engine
coolant at the coolant recovery tank. See Engine
Coolant on page 5-26 for more information.
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.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When the coolant level in the coolant recovery tank is at
the cold fill line, start the vehicle.
If the overheat warning continues, there is one more thing
you can try. You can add the proper coolant mixture
directly to the radiator, but be sure the system is cool
before you do it.
