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
® coolant.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the
engine, radiator, heater core,
and other parts.
If you have to add coolant more
than four times a year, have your
dealer/retailer check your cooling
system.
Notice: If extra inhibitors and/or
additives are used in the vehicle's
cooling system, the vehicle
could be damaged. Use only the
proper mixture of the engine
coolant listed in this manual
for the cooling system.
