OLDSMOBILE BRAVADA 1994 Owners Manual

“Section C: Periodic Maintenance
Inspections” explains important
inspections that your Oldsmobile
dealer’s service department or another
qualified service center should perform.
“Section
D: Recommended Fluids &
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.
Section A: Scheduled
Maintenance Services
Using Your Maintenance
Schedules
This section tells you the maintenance
services you should have done and
when you should schedule them. Your
Oldsmobile dealer knows your vehicle
best and wants you to be happy with it.
If you go to your dealer for your service
needs, you’ll know that GM-trained and
supported service people will perform
the work using genuine GM parts.
These schedules are for vehicles that:
carry passengers and cargo within
recommended limits.
You will find
these limits
on your vehicle’s
Certificatioflire label. See the
Index
under Loading Your Vehicle.

1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,
CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 1OW-
30), see the Index under Engine Oil.
2. Chassis Lubrication - Lubricate the
transmission shift linkage, parking
brake cable guides, underbody contact points and linkage. Lubricate the front
suspension and steering linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions
in this
manual. See
Tires, Inspection G.
Rotation in the Index. Check the
tires for uneven wear or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Inspection - Inspect the drive belt
for cracks, fraying, wear and proper
tension. Replace as needed.
5. Cooling System Service‘: - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to
GM Specification
6038-M. Keep coolant at the proper
mixture as specified. See
CooZant in
the
Index. This provides proper
freeze and boil protection, corrosion
inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps. Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
4. Engine Accessory Drive Belt
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
6. Transmission Service - Change
both the fluid and filter every 15,000
miles
(25 000 lun) if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police
If you do not use your vehicle under
any of these conditions, change both
the fluid and filter every
100,000
miles (166 000 lun) .
Replace spark plugs with the proper
type. See
Replacement Parts in the
Index.
8. Spark Plug Wire Inspection‘%t -
Inspect for burns, cracks or other
damage. Check the boot
fit at the
coils and at the spark plugs. Replace
wires as needed.

9. Air Cleaner Filter Replacement': -
Replace every 30,000 miles (50 000
km) or more often under dusty
conditions. Ask your dealer for the
proper replacement intervals for your
driving conditions.
10. Fuel Tank, Cap and Lines
Inspection*t
- Inspect fuel tank,
cap and lines (including fuel rails
and injection assembly) for damage
or leaks. Inspect fuel cap gasket for
an even filler neck imprint or any
damage. Replace parts as needed.
1 1. Positive Crankcase Ventilation
(PCV) System 1nspection':t
-
Inspect the system for proper
function. Replace any worn, plugged
or collapsed hoses and seals.
Replace valve only if necessary.
12. Fuel Filter Replacement'$t -
Replace the fuel filter every 30,000
miles (50 000 ltrn), or sooner if
clogged.
13. Engine Timing and Distributor Check':'t
- Adjust the timing to
the underhood label specifications.
Inspect the inside and outside of the
distributor cap and rotor for craclts, carbon tracking and corrosion.
Clean or replace
as needed.
14. Differential (Axle) Service-Check
rear/front differential fluid level and
add as needed. Check constant
velocity joints and axle seals for
leaking.
Locking Rear Differential -Drain
fluid at first engine oil change and
refill. Check fluid level and add as
needed at subsequent oil changes. In
dusty areas, or trailer towing
applications, drain fluid at every
15,000 miles (25 000 ltm) and refill.
More frequent lubrication may be
required during heavy-duty or off-
road use. A fluid loss in this system
may indicate
a problem. Have it
inspected and repaired at once.
15. Brake Systems Inspection-When
the engine oil is changed, inspect
the lines and hoses for proper
hookup, binding, leaks, craclts,
chafing, etc. Check the parking
brake adjustment and the fluid level
in the master cylinder. A low brake
fluid level can indicate worn disc
brake pads which may need to be
serviced.
A fluid loss in this system may indicate a problem. See
the
Index under Brake System Warning
Light. When the wheels are
removed for rotation, inspect disc
brake pads for wear and rotors for
surface condition. Also inspect
drum brake linings for wear and
craclts. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc. at the
same time.
You may need to have your brakes
inspected more often
if your driving
habits or conditions result in
frequent braking.
16. Transfer Case Fluid Change -In
heavy or frequent trailer towing
applications, drain fluid and refill
every
30,000 miles (50 000 ltm).

remove foot pressure
from the regular brake pedal. Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism's holding ability: Shift to P (Park). Then release all brakes.
At least every spring, use plain water to flush any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and other debris can collect.
Check rear/front differential fluid level and add as needed. Check constant velocity joints and
axle seals for leaking.
Check transfer case fluid level. Check vent hose at transfer case for ltinlts and proper installation.
More frequent lubrication may be required on heavy-duty off-road use.
A fluid loss may indicate a
problem. Have it inspected and repaired
