you decide it’s safe to lift the hood, here’s what
you’
I1 see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Fan
3.8L L27 (Code L) Engine
An electric fan under the hood can start up even
when the engine
is not running and can injure
you.
Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.

How to Add Coolant to the Radiator
NOTICE:
Your engine has a specific radiator fill procedure.
Failure to
follow this procedure could cause your
engine to overheat and be severely damaged.
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.)
IC 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.

Fill the radiator with the
proper
mix, up to the
base of the filler neck.
If
you see a stream of
coolant coming horn an
air bleed valve, close the
valve. Otherwise, close
the valve(s) after the
radiator is filled.
5. Rinse or wipe any spilled coolant from the engine
and compartment.
6. Then fill the coolant recovery tank to the COLD
mark.
7. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.

8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch
out for the
engine hns.
9. 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.
10. Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the
BI-~OWS on the pressure cap line up like this.
1 1 - Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine
is cold.

Radiator Pressure Cap Power Steering Fluid
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows
on the cap
line up with the overflow tube on the radiator
filler neck.
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
AC@ thermostat
is recommended. 3.1L
L82 (Code M) Engine
3.8L L27 (Code L) Engine
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
