When adding coolant, it is important that you
use only DEX

COOL
R
(silicate

free) coolant.
If coolant other than DEX

the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner

the engine.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a 50/50 mixture of
clean, drinkable water and DEX
-
COOL
R
engine
coolant at the coolant recovery tank. See “Engine
Coolant” in the Index 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. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
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

coolant.
