1995 CHEVROLET S10 engine coolant

Downloaded from www.Manualslib.com manuals search engine 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 fan.
7. 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.
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 the pressure
cap line up like
this.

If your vehicle has four-wheel drive, you will have a remote oil filter. There
is a special access door in the steering linkage shield assembly located under
the radiator support. Twist the screw to lock or unlock the door.
Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-1 8 O C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could
even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
Used oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose of oil by putting
it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead, recycle it by taking it
to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
Air Cleaner
To remove the round air cleaner filter for the 4.3L (VIN 2) engine, turn the
wing nuts counterclockwise. Remove the cover and change the filter. Care
should be taken during reassembly to ensure that the cover is on straight and
the wingnuts
are properly tightened.
= To avoid ingesting
dust in the engine, the
arrow on the air
cleaner lid should
point
to the front of
the engine.

Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.
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 vehicle will:
Give freezing protection down to -34°F (-37 “C).
Give boiling protection up to 262°F (128 “C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages 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,” or “GM Specification
6043-M’ with the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 603%”’ or “GM Specification 6043-M” with the 2.2L
(LN2) Code 4 engine. Use GM Coolant Supplement (Sealer) with a
complete coolant flush and refill. If you use this mixture, you don’t need to
add anything else.

Downloaded from www.Manualslib.com manuals search engine 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.
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when the engine is cold
and follow the steps under “Adding Coolant” for the proper way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to add extra
inhibitors or additives which claim to improve the system. These
can be harmful.
Adding Coolant
E I
6-22

Downloaded from www.Manualslib.com manuals search engine To Check Coolant
When your engine is cold, the coolant level should be at ADD, or a little
higher. When
your engine is warm, the level should be up to FULL HOT, or
a little higher.
To Add Coolant
If you need more coolant, add the proper mix at the coolant recovery tank.
Add coolant mix at the recovery tank, but be careful not to spill it.
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.

Downloaded from www.Manualslib.com manuals search engine When you replace
your radiator pressure
cap, a
GM cap is
recommended. See
"Service Replacement
Part and Filter
Recommendations"
in
the Index.
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.
