Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible
in the coolant surge tank. If the
coolant inside the coolant surge
tank is boiling, do not do anything
else until it cools down. If coolant
is visible but the coolant level is not
at or above the cold fill mark, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant surge tank, but be sure the
cooling system is cool before this is
done. See Engine Overheating on
page 10 23 for more information.
The coolant reservoir is located
on the passenger side of the
engine compartment. See Engine
Compartment Overview on
page 10 10 for more information
on location.
The coolant level should be at
or above the cold fill line on the
coolant surge tank. If it is not,
there could be a leak in the
cooling system.
How to Add Coolant to the
Coolant Surge Tank
WARNING
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.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.

WARNING
The electric cooling fans under
the hood can start up even when
the engine is not running and
can cause injury. Keep hands,
clothing, and tools away from
any underhood electric fan.
WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you
turn the surge tank pressure
cap even a little they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap.
