engine coolant CHEVROLET TRACKER 1995 User Guide

When you open the hood, you’ll see the following on
the 16-valve engine:
1. Battery
2. Automatic Transmission Dipstick (if equipped)
3. Oil Fill Cap
4. Brake muid Reservoir
5. Air Cleaner
6. Engine Coolant Reservoir
7. Power Steering Reservoir
8. Radiator Pressure Cap
9. Electric Engine Fan
10. Windshield Washer Reservoir
11. Main Fuse Box Before
closing the hood, be sure all the filler caps are
on.
Then lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop to its retainer. Then just let the hood
down and close it firmly.

Front Axle Engine Coolant
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Periodic Maintenance Inspections” and “Scheduled
Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some 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.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index. 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:
0 Give freezing protection down to -33°F (-36°C).
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 1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.

I 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
8-Valve Engine
To Check Coolant
When your engine is cold, the coolant level should be at
LOW, or
a little higher. When your engine is warm, the
level should be
up to FULL, or a little higher.

16-Valve Engine
To Add Coolant
If you need more coolant, add the proper mix ut the
coolant recovery tank.
Add coolant mix at the recovery tank, but be careful not
to spill it.

Radiator Pressure Cap Power Steering Fluid
I 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 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.
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.
