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 5-22 for more information.
CAUTION:
{
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle's
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The engine
could catch fire and you or others could be
burned. Use a 50/50 mixture of clean, drinkable
water and DEX-COOL

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