1994 CHEVROLET S10 cooling

Downloaded from www.Manualslib.com manuals search engine If the differential is at operating temperature (w,arm), add enou\
gh 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.
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 -20 “F (-29” C), or -34°F (-37 “C) in
Canada and for vehicles with the cold climate option.
e Give boiling protection up to 258°F (125°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 mi,xture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 603%” or “GM Specification
6043-M ”for 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 ”for the 2.2L (LN2)
Code 4 engine 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 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.
Some conditions, such as air trapped in the cooling system, ca\
n affect the
coolant level in the radiator. Check the coolant level when th\
e engine
is cold
and foilow 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.
I 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
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
I
If you need more
coolant, add the
proper
mix at the
coolant recovery tank.

replace them only with new
GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel \
nuts for your
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain\
clearance to the body and chassis.

Downloaded from www.Manualslib.com manuals search engine Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed
in this section. Make sure
whoever services your vehicle uses these. All parts should be \
replaced and
all necessary repairs done before you or anyone else drives the vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* - ALWAYS USE
API SERVICE SH OR SG ENERGY CONSERVING I1 OILS
OF THE
PROPER VISCOSITY. The “SH” or
“SG’ designation may be shown
alone or in combination with others, such as “SWCD”, or
“SH, SG,
CD,” or “SGKD”, etc. To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE 5W-30), see “Engine
Oil” in the Index.
2. CHASSIS LUBRICATION - Lubricate the front suspension, ball
joint, steering linkage, and transfer case shift linkage, parking brake\

cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first
.
Ball joints should not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them or they could be damaged.
Also, be sure
to check all the vehicle fluid levels at this time.
3.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “\
GM
Specification 6038-M” (4.3L engine) or “GM Specification 6043-M”
(2.2L engine). See “Engine Coolant” in the Index for the proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them if they are cracked, \
swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
4. AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
5. FRONT WHEEL BEARING REPACK (%WHEEL DRIVE
ONLY) - Clean and repack the front wheel bearings at each brake
relining, or at the specified interval, whichever comes first.
