CHEVROLET SUBURBAN 1995 Owners Manual

Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together
if the vehicle is to have really good
braking. Vehicles we design and test have top-quality
GM brake parts in
them, as your vehicle does when it is new. When you replace parts of your
braking system
- for example, when your brake linings wear down and
you have to have new ones put in - be sure you get new genuine GM
replacement parts. If you don’t, your brakes may no longer work properly.
For example, if someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes can change
- for
the worse. The braking performance you’ve come to expect can change
in
many other ways if someone puts in the wrong replacement brake parts.
Front Shock Absorbers
The front shock absorbers of your vehicle do many things. They help the
vehicle ride smoothly and also control the travel of the suspension system.
When the shock absorbers are serviced, any replacement shock absorbers
must be the same
as the original equipment shock absorbers in both
extended length and strength.
I NOTICE:
If you use shock absorbers that are not the same as the original
shock absorbers, the shock absorbers or suspension system
could be damaged.
Windshield Wiper Blade Inserts
To replace your
windshield wiper
blade inserts, lift the
wiper arm and rotate
the blade until
it is
facing away from
the
windshield.
Unlatch the end of the insert from the holding clips. Remove the insert
and
slide a new one in place. Make sure the blade is secured in the clips.

Air Conditioning
Every now and then have your dealership check your air conditioning
system to be sure
it has not lost any cooling ability. If you think the system
is not working properly, have your dealership check it out as soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4°C).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s maintenance schedule will tell
you how often to lubricate them.
See “Recommended Fluids and Lubricants”
in the Index for the proper
lubricant to use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause the lock
to bind. De-icers which contain
alcohol could also wash away
the lubricant, so be sure to lubricate the lock
after using
a de-icer of this type.
Battery
Every new GM vehicle has a Delco Freedom’ battery. You never have to
add water
to one of these. When it’s time for a new battery, we recommend
a Delco Freedom@ battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
