How to Add Coolant to the
Radiator
If the vehicle has a diesel engine,
see “How to Add Coolant to the
Radiator” under “Van Models” in
the Cooling System section of the
Duramax diesel manual for the
proper radiator fill procedure.
{
WARNING
An electric engine cooling fan
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.
If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done.
1. Remove the radiator pressure
cap when the cooling system,
including the radiator pressure
cap and upper radiator hose, is
no longer hot. Turn the pressure
cap slowly counterclockwise
until it first stops. Do not
press down while turning the
pressure cap.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap,
but now push down as you turn
it. Remove the pressure cap.
