How to Add Coolant to the Coolant
Recovery Tank for Gasoline Engines
If your vehicle has a diesel engine, see "How to
Add Coolant to the Coolant Recovery Tank" under
"Van Models" in the Cooling System section of
®
the DURAMAX Diesel Supplement for the proper
coolant fill procedure.
If you have not found a problem yet, but the coolant
level is not at the COLD FILL mark, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
coolant at the coolant recovery tank. See Engine
Coolant on page 5-22 for 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.

CAUTION: (Continued)
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:
•
When using concentrated washer fluid, follow the
manufacturer's instructions for adding water.
•
Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts of
the washer system. Also, water does not clean as
well as washer fluid.
•
Fill your washer fluid tank only three-quarters full
when it is very cold. This allows for expansion if
freezing occurs, which could damage the tank if
it is completely full.
•
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
