1993 BUICK REGAL air condition

In most cases, you will not need to have your wheels
aligned again. However, if
you notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may need to be reset.
If you notice your
vehicle vibrating when driving on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted.
If wheel nuts keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If the wheel leaks air
out, replace it (except some aluminum wheels, which
can sometimes be repaired). See your Buick dealer if
any
of these conditions exist.
Your dealer will know the kind of wheel you need.
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, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, and wheel nuts for your Buick
model.
A CAUTION:
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.

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal of important components can significantly
affect the quality of the air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle. To help protect
our environment, and to help keep your vehicle in
good
condition, please maintain your vehicle properly.

Buick regularly sends its dealers useful service bulletins
about Buick products. Buick monitors product
performance in the field. We then prepare bulletins for
servicing our products better. Now, you can get
these
bulletins too. Bulletins cover various subjects.
Some pertain to the
proper
use and care of your vehicle. Some describe
costly repairs. Others describe inexpensive repairs
which, if done on time with the latest parts, may avoid
future costly repairs. Some bulletins tell a technician
how
to repair a new or unexpected condition. Others
describe a quicker way to fix your vehicle. They can
help a technician service your vehicle better.
Most bulletins apply
to conditions affecting a small
number of cars or trucks. Your Buick dealer or a
qualified technician may have to determine if a specific
bulletin applies to your vehicle.
You can subscribe to all Buick bulletins. This way
you’ll
get them as they come out. You can wait a while and get
an index to the bulletins. You can also get individual
bulletins. However,
you’ll need the index to identify
them.
