MAINTENANCE OR REPAIR?
Maintenance includes routine inspecti
ons, adjustments, and replacement of
parts which show signs of normal wear . Maintenance compensates for wear or
deterioration. Repair implies that someth ing has broken or is not working. A
need for a repair is often caused by lack of maintenance. for example: draining
and refilling automatic transmission fl uid is maintenance recommended at
specific intervals. Failure to do this can shorten the life of the
transmission/transaxle, requiring very expen sive repairs. While no maintenance
program can prevent items from eventually breaking or wearing out, a general
rule is true: MAINTENANCE IS CHEAPER THAN REPAIR.
Two basic mechanic's rules should be mentioned here. First, whenever the left
side of the vehicle or engine is refe rred to, it means the driver's side.
Conversely, the right side of the vehi cle means the passenger's side. Second,
screws and bolts are removed by turn ing counterclockwise, and tightened by
turning clockwise unless specifically noted.
Safety is always the most important rule. Constantly be aware of the dangers
involved in working on an automobile and take the proper precautions. Please
refer to the information in this se ction regarding SERVICING YOUR VEHICLE
SAFELY and the SAFETY NOTICE on the acknowledgment page.
AVOIDING THE MOST COMMON MISTAKES
Pay attention to the instructions prov ided. There are 3 common mistakes in
mechanical work:
1. Incorrect order of assembly, di sassembly or adjustment. When taking
something apart or putting it toget her, performing steps in the wrong
order usually just costs you ex tra time; however, it CAN break
something. Read the entire proc edure before beginning. Perform
everything in the order in which the instructions say you should, even if
you can't see a reason for it. When you' re taking apart something that is
very intricate, you might want to draw a picture of how it looks when
assembled in order to make sure you get everything back in its proper
position. When making adjustments, per form them in the proper order.
One adjustment possibly will affect another.
2. Overtorquing (or undertorquing). While it is more common for overtorquing to cause damage, undertorquing may allow a fastener to
vibrate loose causing serious dam age. Especially when dealing with
aluminum parts, pay attention to tor que specifications and utilize a torque
wrench in assembly. If a torque figure is not available, remember that if
you are using the right tool to perfo rm the job, you will probably not have
to strain yourself to get a fast ener tight enough. The pitch of most
threads is so slight that the te nsion you put on the wrench will be
multiplied many times in actual fo rce on what you are tightening.
There are many commercial products avai lable for ensuring that fasteners won't
come loose, even if they are not torqued just right (a very common brand is

b. If fluid is warm, the le
vel should be close to the ADD mark, either
above or below.
c. If fluid is too hot to touc h, the level should be at the FULL mark.
3. If the fluid level is low, add Dexr on®II automatic transmission fluid (ATF)
through the dipstick tube. This is eas ily done with the aid of a funnel.
Check the level often as you are f illing the transmission. Be extremely
careful not to overfill it. Overfilling will cause slippage, seal damage and
overheating. Approximately 1 pint (0.473L) of ATF will raise the fluid level
from one notch/line to the other.
If the fluid on the dipstick appears discolored (brown or black), or smells burnt,
serious transmission troubles, probably due to overheating, should be
suspected. The transmission should be inspected by a qualified technician to
locate the cause of the burnt fluid.

LEVEL CHECK
Fig. 1: Removing filler plug to check rear axle lubricant
The gear lubricant in the drive axle should be checked every 12 months or
15,000 miles (24,000km).
1. Raise the car and support on jackstands as close to level as possible. \
2. Remove the filler plug from the side of the drive axle housing.
3. If lubricant begins to trickle out of the hole, there is enough and you need
not go any further. Otherwise, carefully insert your finger (watch out for
sharp threads) and check to see if the lubricant is up to the edge of the
hole.
4. If not, add oil through the hole until the level is at the edge of the hole.
Most gear lubricants come in a pl astic squeeze bottle with a nozzle;
making additions simple.
5. Install and tighten the filler plug.
DRAIN AND REFILL
The rear axle should have the gear lubricant changed every 7,500 miles
(12,000km). If equipped with a limited slip differential, be sure to add 4 oz.
(118mL) of GM lim ited slip additive part No. 1052358.
1. Raise the car and support on jackst ands. Place a container under the
differential to catch the fluid.
2. Remove the bolts retaining the par king brake cable guides and position
aside.
