Problems on the Road
If the coolant inside the coolant recovery
tank
is boiling, don’t do anything else
until it cools down.
The coolant level should be at or above
“FULL.” 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. I NOTICE:
I
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
[f there seems to be no leak, check to see
if the electric engine fan is running.
If the
mgine is overheating, the fan should be
running. If it isn’t, your vehicle needs
service.
How to Add Coolant to the Coolant
Recovery
Tank
[f you haven’t found a problem yet, but
:he coolant level isn’t at or above the
“FULL” mark, add a 50/50 mixture of
:lean water (preferably distilled) and a
xoper antifreeze at
the coolant recovery
:a&. (See “Engine Coolant” in the Index
for more information about the proper
:oolant mix.)

lubricant.
If the differential is at operating
temperature (warm), add enough lubricant
to raise the level to the bottom of the filler
plug hole.
If the differential
is cold, add enough
lubricant to raise the level to
1/2 inch (12
mm) below the filler plug hole.

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, see “Engine Overheating”
in
the Index.
The proper coolant for your Geo will:
Give freezing protection down to
-20°F (-29”C), or -34°F (-37°C)
in
Canada and for vehicles with the cold
climate option.
Give boiling protection up to 258°F
(125°C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
6038-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to
“GM Specification
6038-M”
with a complete coolant flush

Radiator Pressure Cap
16-Valve Engine
To Add Coo1ant:If you need to add more
coolant, add the proper mix
qt the coolant
recovery tank. Add
coolant
mix at the recovery tank, but
be careful not to spill it.
NOTICE:
Your radiator cap is a 13 psi (90 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage
from over-
heating.
Be sure the amows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace
your radiator pressure
zap, 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
Ace' thermostat is recommended.
