GENERAL INFORMATION & MAINTENANCE

HOW TO USE THIS INFORMATION
The introductory part of this repair gui de is intended to help you learn more
about the inner workings of your Camaro while saving you money on its upkeep
and operation.
The beginning of the repair guide will likely be referred to the most, since that is
where you will find information for maintenance and tune-up. The other
information deals with the more complex systems of your vehicle. Systems
(from engine through brakes) are covered to the extent that the average do-it-
yourselfer can attempt. This repair guide will not explain such things as
rebuilding a differential because the ex pertise required and the special tools
necessary make this uneconomical. It will, however, give you detailed
instructions to help you change your own brake pads and shoes, replace spark
plugs, and perform many more jobs that can save you money and help avoid
expensive problems.
A secondary purpose of this repair guide is a reference for owners who want to
understand their vehicle and/or their mechanics better.
WHERE TO BEGIN
Before removing any bolts, read through t he entire procedure. This will give you
the overall view of what tools and supplies will be required. So read ahead and
plan ahead. Each operation should be approached logically and all procedures
thoroughly understood before attempting any work.
If repair of a component is not considered practical, we tell you how to remove
the part and then how to insta ll the new or rebuilt replacement. In this way, you
at least save labor costs.
AVOIDING TROUBLE
Many procedures in this repair guide r equire you to "label and disconnect ..." a
group of lines, hoses or wires. Don't be think you can remember where
everything goes - you won't. If you hook up va cuum or fuel lines incorrectly, the
vehicle may run poorly, if at all. If you hook up electrical wiring incorrectly, you
may instantly learn a very expensive lesson.
You don't need to know the proper name for each hose or line. A piece of
masking tape on the hose and a piece on its fitting will allow you to assign your
own label. As long as you remember your own code, the lines can be
reconnected by matching your tags. Re member that tape will dissolve in
gasoline or solvents; if a part is to be washed or cleaned, use another method
of identification. A permanent felt-tipped marker or a metal scribe can be very
handy for marking metal parts. Remove any tape or paper labels after
assembly.
