When you decide it's safe to lift the hood, here's what
you'll see: If the coolant inside the coolant recovery tank is boiling,
don't do anything else until
it cools down.
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
The coolant level should be at least up to the ADD mark.
If it isn't, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else
in
the cooling system.

/A C,* UTION:
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 radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have to
turn the pressure cap.

How to Add Coolant to the Radiator
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 counterclockwise
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.
p :. I
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 DEX-COOL@
coolant mixture, LIP to the base of the filler neck.
(See “Engine Coolant‘’
in the Index for more
information about the proper
coolant mixture.)
4. Then fill the coolant recovery tank to the ADD mark.
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off’.

6. Start the engine and let it run until you can feel the
upper radiator hose getting
hot. Watch out for the
engine cooling fan.
7. By this time, the coolant level inside the I-' d' lator
filler neck rnay be lower.
If the level is lower, add
more
of the proper DEX-COOL@ coolant mixture
through the filler neck until the level reaches the
base of the filler neck.
8. 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
arrows
on thti pressure cap line up like this.

Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the coolant recovery tank.
A CAUTION:
Add coolant mixture at the recovery tank, but be careful
not to spill it.
Thrning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding 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.
I A 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. Don’t spill coolant on a hot engine.

Radiator Pressure Cap 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.
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.
