It takes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank was half
full, but it
actually took a little more or less than half the tank’s capacity to fill the
tank.
The gage moves a little when you turn a corner or speed up.
0 The gage doesn’t go back to empty when you turn off the ignition.
None of these indicate a problem with the fuel gage.
For information on how to fill your fuel tank, see “Fuel
- Filling Your
Tank”
in the Index.
For your
fuel tank capacity, see “Fuel -Tank Capacity” in the Index.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. Most of the time, the gage
pointer will show your coolant temperature at 210°F (99”C), or less. But,
if
you are pulling a heavy load or driving up hills, your coolant temperature
may rise and fall near
the red 260°F (1 28°C) mark. This is normal. If the
gage pointer moves
to the red 260°F (1 28°C) mark, your engine is too hot!
It means that your engine coolant has overheated. 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 shows what to do. See “Engine
Overheating”
in the Index.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used.
If you’re not sure, ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information’’ booklet.
NOTICE:
R-134A refrigerant is not compatible with R-12 refrigerant in
an air conditioning system. R-12 in an R-134A system will cause
compressor failure, refrigerant oil sludge, or poor air
conditioning system performance.
