1993 BUICK REGAL maintenance

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 kPa).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell
you the pressure, especially if you have radial tires --
which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back
on.
They help prevent leaks by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended
in the
Maintenance Schedule. See “Scheduled Maintenance
Services”
in the Index.
I
I‘
Use this rotation pattern.
After the tires have been rotated, adjust the front and
rear inflation pressure
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in the
Index.

White Sidewall Tires
Your Buick dealer has a GM White Sidewall Tire
Cleaner. You can use a stiff brush with it.
Weatherstrips
These are places where glass or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not stick or squeak. Apply silicone grease
with a clean cloth at least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish
if they remain on painted
surfaces. Use cleaners that are marked safe for painted
surfaces for these stains.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas
of finish damage can be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on
the underbody. If these are not
removed, accelerated corrosion (rust) can occur
on the
underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring,
flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle washing system
can do
this for you,

Introduction
A Word About Maintenance
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how
you’ll drive it. You may drive very short
distances only
a few times a week. Or you may drive
long distances all the time in very
hot, dusty weather.
You may use your vehicle in making deliveries. Or you
may drive it to work, to
do errands or in many other
ways.
Because of all
the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements
than you will
find in the schedules in this part.
So please read this part
and note how
you drive. If you have any questions on
how
to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners choose to
have their maintenance work done. Your dealer can be
relied upon to use proper parts and practices.

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.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section
A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
e dangerous. In trying to do some jobs, you ca
le seriously injured.
Do your own maintenanc
work only if you have the required know-how and
:he proper tools and equipment for the job.
If you
have any lubt, have a qualified technic’
1 do
the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information GM publishes. You
will find a list of
publications and how to get them
in this manual. See
“Service Publications”
in the Index.
“Section B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Section
C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.

ProCarManuals.com

“Section D: Recommended Fluids and Lubricants” lists
some products GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Section
E: Maintenance Record” provides a place for
you to record the maintenance performed
on your
vehicle. Whenever
any maintenance is performed, be
sure to write it down in this section. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.

Services
Using Your Maintenance Schedules
