How to Add Coolant to the Radiator I
A@' #, I
1. You can 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 to the left until
it first stops.
(Don't press down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still
some pressure left.

2. Then keep turning
the pressure cap,
but now push down
as you turn it.
Remove the
pressure cap.

3. Fill the radiator
with the proper
mix, up to the base
of the filler neck.
E
4. Then fill the coolant recovery tank to "FULL
COLD."
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap
off.

Bp. 6. Start the engine and
let
it run until you
can feel the upper
radiator hose
getting hot. Watch
out for the engine
fans.
7. By this time the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper mix through the filler neck until
the level reaches the base
of the filler neck.

the pressure cap

parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change.
If you use these, you
don’t need
to add anything else.
I k!, CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too
hot but you wouldn’t get the overheat
warning. Your engine could catch fire
and you or
others could be burned.
Use a 5050 mix of clean
water and a proper antifreeze.
I
I NO IC i:
IT you use an Improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered
by your
warranty.
Too much water in the mix can treeze
and crack the engine, radiator, heater core and other
parts.
Adding Coolant

To Check Coolant: When your engine is cold, the
coolant level should
be at “FULL COLD,’’ or a little
higher. When your engine is
warm, the level should be
up to “FULL HOT,” or a little higher.
To Add Coolant: If you need more coolant, add the
proper mix at the coolant recovery tank.

I
A CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can
allow steam and
scaldlng
liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have
to add coolant at the radiator. Never
turn the radiator pressure cap -- even a little -
when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill
it.
A CAUTION: I
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
-..d
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

When you replace your radiator pressure cap, an AC@
cap is recommended.

Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When
you replace your thermostat, an ACS thermostat
is recommended.
Power Steering Fluid

How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.

“FULL COLD” mark.
When adding power steering fli or making a
complete fluid change, always use the proper
fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.

Windshield Washer Fluid
To Add:
Open the cap labeled
“WASHER FLUID ONLY.”
Add washer fluid until the
