Engine Coolant
The following explains your cooling
system and
how to add coolant when it
is low. If you have a problem with
engine overheating or
if you need to add
coolant to your radiator, see the Index
under Engine Overheuling.
The proper coolant for your Pontia’c
will:
Give freezing protection do;wn to
Give boiling protection up to 262°F
Protect against rust and corrosion.

Let the warning lights work as they
What to Use:
Use a mixture of one-half dean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825-M,” which won’t darnage

aluminum parts. You can also use a
recycled coolant conforming to
GM
Specification 1825-M with a complete
coolant flush and refill. If you use this
mixture, you don’t need to add
anything else.
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
50/50 mix of clean
water and
a Droner antifreeze.

NOTICE
If 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 freeze 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
COLD or a little
higher. When your engine is warm, the
level should be up to
HOT or a little
higher.
If this light comes on, it means you’re
low on engine coolant.
To Add Coolant:
I€ you need more coolant, add the
proper mix at the coolant recovery
tank. n

Radiator Pressure Cap
Dm
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

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.
