engine overheat GMC SAVANA 1996 User Guide

5. Put the flat end of the extension on an angle through
the hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will hear two “clicks” when the tire is up all the
way. Try
to move the tire with your hands to make
sure it is securely in place.
Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
”rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transmission or other parts
of the
vehicle can overheat. That
could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little
as possible. Don’t
spin the wheels above
35 mph (55 kmh) as shown
on the speedometer.

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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.
A 50/50 mixture of water and the proper coolant for
your vehicle will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129 O C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If
silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.

What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else. Adding
only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50/50 mix of clean
water and
DEX-COOL TM (orange-colored,
silicate-free) antifreeze.

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.
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.
Checking Coolant
When your engine is cold, the coolant level should be at
FULL COLD, or a little higher.

Adding Coolant
If you need more coolant, add the proper mix ut the
coolcrnt mcoveq* tmk.
A CAUTION:
Tbrning the radiator pressure cap when the
engine and radiator are hot can allow steam and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little
-- when the engine and radiator are hot.
Add coolant mix at the recovery tank. but be careful
not
to spill it.
A CAUTION:
You can be burned if' you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it
will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
Radiator Pressure Cap
The radiator pressure cap nust be tightly installed with
the arrows
on the cap lined up with the overflow tube on
the radiator filler neck.
NOTICE:
Your radiator cap is a 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.
