2000 CADILLAC CATERA cooling

6-22
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture 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.
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
The surge tank is located behind the air cleaner on the
passenger's side of the engine.
The cooling system when hot is under a lot of pressure.
If the low coolant warning light on the instrument panel
appears, you will need to add coolant.

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels or wheel
bolts, replace them only with new GM original
equipment parts. This way, you will be sure to have
the right wheel and wheel bolts for your vehicle.
CAUTION:
Using the wrong replacement wheels and wheel
bolts 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 and
wheel bolts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.
Used Replacement Wheels
CAUTION:
Putting a used wheel on your vehicle is dangerous.
You can't know how it's been used or how far it's
been driven. It could fail suddenly and cause an
accident. If you have to replace a wheel, use a new
GM original equipment wheel.
