Engine Coolant Temperature Gage
210
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 been
operating your vehicle under normal driving conditions,
you should 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
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 aangerously low oil
level or other problems causing low oil pressure.

Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If you don’t shift down, you might have to use your brakes
so
much that they would get hot and no longer work well.
On a long uphill grade,
shift down and reduce your speed to around 45 mph
(70 km/h) to reduce the possibility of engine and transmission overheating.
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 turning
the engine
off. If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hi//s
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. When parking uphill,
turn your wheels
away from the curb. When parking downhill,
turn your wheels into the
curb.
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-wheeldrive 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.

NOTICE:
Do not tow with sling-type equipment or the rear bumper
system will be damaged.
Use wheel lift or car-carrier equipment.
Additional ramping may be required for car-carrier equipment.
Use safety chains and wheel straps.
If your vehicle has the four-wheel drive option, a dolly MUST
be used under the front wheels when towing from the rear.
Engine Overheating
You will find a coolant temperature gage on your vehicle's instrument
panel.
If Steam Is Coming From Your Engine

Downloaded from www.Manualslib.com manuals search engine 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 -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 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.
