AIR CONDITIONING COMPONENTS
REMOVAL & INSTALLATION
Repair or service of air conditioni ng components is not covered by this
information, because of the risk of personal injury or death, and because of the
legal ramifications of servicing these components without the proper EPA
certification and experience. Cost, perso nal injury or death, environmental

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 160
damage, and legal considerations (such as t
he fact that it is a federal crime to
vent refrigerant into the atmosphere), dictate that the A/C components on your
vehicle should be serviced only by a Motor Vehicle Air Conditioning (MVAC)
trained, and EPA certified aut omotive technician.
If your vehicle's A/C system uses R-12 re frigerant and is in need of recharging,
the A/C system can be c onverted over to R-134a refrigerant (less
environmentally harmful and expensive). Refer to General Information &
Maintenance for additional information on R- 12 to R-134a conversions, and for
additional considerations dealing with your vehicle's A/C system.

ENGINE

MECHANICAL ENGINE
REMOVAL & INSTALLATION
In the process of removing the engine, you will come across a number of steps
which call for the removal of a separ ate component or system, such as
"disconnect the exhaust system " or "remove the radiator." In most instances, a
detailed removal procedure can be found elsewhere in this repair guide.
It is virtually impossible to list each individual wire and hose which must be
disconnected, simply because so many different model and engine
combinations have been manufactured. Careful observation and common
sense are the best possible approaches to any repair procedure.
Removal and installation of the engine ca n be made easier if you follow these
basic points:
• If you have to drain any of the fl uids, use a suitable container.
• Always tag any wires or hoses and, if possible, the components they
came from before disconnecting them.
• Because there are so many bolts and fasteners involved, store and label
the retainers from com ponents separately in muffin pans, jars or coffee
cans. This will prevent conf usion during installation.
• After unbolting the transmission or trans axle, always make sure it is
properly supported.
• If it is necessary to disconnect t he air conditioning system, have this
service performed by a qualified tec hnician using a recovery/recycling
station. If the system does not have to be disconnected, unbolt the
compressor and set it aside.
• When unbolting the engine mounts, a lways make sure the engine is
properly supported. When removing t he engine, make sure that any
lifting devices are properly attached to the engine. It is recommended
that if your engine is supplied with lifting hooks, your lifting apparatus be
attached to them.
• Lift the engine from its compartment sl owly, checking that no hoses,
wires or other component s are still connected.
• After the engine is clear of the compar tment, place it on an engine stand
or workbench.
• After the engine has been removed, y ou can perform a partial or full
teardown of the engine using the procedur es outlined in this repair guide.
