The proper fluid should be added if the
level does not reach the bottom of the
diaphragm when it’s

is low. If you have a problem with
engine overheating or
if you need to add
coolant to your radiator, see the

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 a proper antifreeze.

Using the wrong replacement
wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling
of your
vehicle, make your tires lose air and
make you lose control.
You could
have a collision in which you or
others could be injured. Always use
the correct wheel, wheel bolts, and
wheel nuts for replacement.
-
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer/odorneter
calibration, headlight aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance
to
the body and chassis.
Used Replacement Wheels Tire Chains
Putting a used wheel on your
L vehicle is dangerous. You
can’t know how it’s been used or
how many miles it’s been driven. It could fail suddenly and cause an
accident. If you have to replace a
wheel use a
new GM original
L equiDment wheel.
