Engine Coolant Temperature Gage
I

rc E- -
This gage shows the
engine coolant
temperature.
If the
gage pointer moves into the red area, your
engine
is too hot!
It means that your engine coolant has overheated. If you have bee\
n
operating your vehicle under normal driving conditions, you shou\
ld pull off
the road, stop your vehicle and turn
off the engine as soon as possible.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating” in the Index.
Oil Pressure Gage
40
The oil pressure gage
shows the engine oil
pressure in psi (pounds per square
inch) when the engine
is running. Canadian
vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside temperature and oil
viscosity, but readings above the low pressure zone indicate the normal
operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problems causing low oil pressure.

Downloaded from www.Manualslib.com manuals search engine When towing at high altitude on steep uphill grades, consider the following:
Engine coolant will boil at a lower temperature than at normal\
altitudes.
If
you turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar
to engine overheating.
To avoid this,
let the engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) (or the manual transmission
out of gear and the parking brake applied) for a few minutes before turni\
ng
the engine off. If
you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start
to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into PARK (P)
yet, or into
gear for a manual transmission. Then turn your wheels into the curb if \
facing downhill or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes\
until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
then
shift into PARK (P), or REVERSE
(R) for a manual transmission.
5. If you have a four-wheel-drive vehicle with a manual transfer case
shift lever, be sure
the transfer case is in a drive gear - not in
NEUTRAL
(N).
6. Release the parking brake.

t do anything
else until
it cools down.
The coolant level should be at the
ADD mark. 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.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled
by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn off the engine.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level isn’t \
at ADD, add a
50/50 mixture of clean water (preferably distilled) and a proper antifreeze at
the coolant recovery tank. (See “Engine Coolant’’ in the Index for more
information about the proper coolant
mix.) ..
NOTICE:
In cold weather, water can freeze and crack the engine, radiat\
or,
heater core and other parts. Use the recommended coolant.

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 filler neck may be lower. If the
level is lower, add more of the proper mix through the filler neck unt\
il
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.
Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged, the fan spins faster to provide more air to cool the engine. \
In most every day
driving conditions the clutch
is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer tow\
ing and/or
high outside temperatures, the fan speed increases when
the clutch engages.
So you may hear an increase in fan noise. This is normal and should not be
mistaken
as the transmission slipping or making extra shifts. It is merely \
the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and
the clutch disengages.
You may also hear this fan noise when you start the engine. It will go away
as the fan clutch disengages.

,:
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 le\
vel 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:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F (128°C).
0 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,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 6038-M.
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.
