Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by putting
it in the trash, or by pouring it on the
ground or into sewers, streams, or bodies of
water. Have the coolant changed by an
authorized service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The engine coolant surge tank (2) is in the
engine compartment on the driver side of
the vehicle. See Engine Compartment
Overview 0 25 for location.
The vehicle must be on a level surface.
When the engine is cold, the coolant level
should be at the indicated mark.
Adding Coolant
Caution
If the coolant level is too low, engine
damage may occur. When changing or
adding coolant, fill the coolant surge tank
Caution (Continued)
to the indicator mark on the tank. If both
tanks are empty, refill the main tank (2)
first.
If more coolant is needed, add the proper
DEX-COOL coolant mixture at the surge tank,
but be careful not to spill it.
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
