Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The engine coolant surge tank is located toward the
rear of the engine compartment on the driver side of the
vehicle. For more information on location, see Engine
Compartment Overview on page 6-12.
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 FULL
COLD 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.
When the engine is cold, the coolant level should be at or
above the FULL COLD mark on the side of the coolant
surge tank that faces the front. When the engine is hot,
the level could be higher than the FULL COLD mark.
If the coolant is below the FULL COLD mark when the
engine is hot, there could be a leak in the cooling system.
If the LOW COOLANT message on the Driver Information
Center (DIC) comes on and stays on, it means the
vehicle is low on engine coolant. See DIC Warnings and
Messages on page 3-60. A low coolant level should be
indicated by a LOW COOLANT message on the Driver
Information Center (DIC). If it is, there could be a leak in
the cooling system.
How to Add Coolant to the Coolant
Surge Tank
{ 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.
