< 1.8L Engine>Tension/ wllevO-RING INSTALLATION
(1) Clean sealing surface.
(2) Make sure O-ring does not have any scratches.
(3) Connect fitting, install fastener, and torque to amount
shown in the illustration.
The internal parts of the refrigeration system will remain in
a state of chemical stability as long as pure-moisture-free
R-12 and refrigerant oil is used. Abnormal amounts of dirt,
moisture of air can upset the chemical stability and cause
operational troubles or even serious damage if present in
more than minute quantities.
When it is necessary to open the refrigeration system, have
everything you will need to service the system ready so the
system will not be left open any longer than necessary. Capor plug all lines and fittings as soon as they are opened to
prevent the entrance of dirt and moisture. All lines and
components in parts stock should be capped or sealed until
they are ready to be used. All tools, including the refrigerant
dispensing manifold, the gauge set manifold and test hosesshould be kept clean and dry.
COMPRESSOR DRIVE BELT ADJUSTMENT N24FJAESatisfactory performance of the air conditioning system is
dependent upon drive belt condition and tension. If the proper
tensions are not maintained, belt slippage will greatly reduce airconditioning performance and drive belt life. To avoid such
adverse effects, the following service procedure should be
followed:
(1) Measure the deflection with a force of
IOON (22 Ibs.)applied to belt mid-point between tension pulley and
compressor pulley.
(2) Any belt that has operated for a minimum of one half-hour
is considered to be a “used” belt. Adjust air conditioning
drive belt at the time of new-car preparation.
(3) Check drive belt tension at regular service intervals and
adjust as needed.
Standard value:
When a new belt is installed<1.8L Engine>4-5 mm
(.16-.2 in.)
<2.0L DOHC Engine> 4.5-5 mm (.18-.2 in.)
When the used belt’s tension is adjusted
5.5-6 mm
(.22-.24 in.)

24-24 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
COMPRESSOR NOISENUFIABWhen investigating an air conditioning related noise, you must
first know the conditions when the noise occurs. These
conditions are: weather, vehicle speed, in gear or neutral,
engine temperature or any other special conditions.
Noises that develop during air conditioning operation can oftenbe misleading. For example: what sounds like a failed front
bearing or connecting rod, may be caused by loose bolts, nuts,mounting brackets, or a loose clutch assembly. Verify acces-
sory drive belt tension (power steering, or alternator).
Improper accessory drive belt tension can cause a misleading
noise when the compressor is engaged and little or no noise
when the compressor is disengaged.
Drive belts are speed sensitive. That is, at different engine
speeds, and depending upon belt tension, belts can develop
unusual noises that are often mistaken for mechanical prob-
lems within the compressor.
Adjustment Procedures
(1) Select a quiet area for testing. Duplicate conditions as
much as possible. Switch compressor on and off several
times to clearly identify compressor noise.
To duplicate high ambient conditions (high head pressure),restrict air flow through condenser. Install manifold gauge
set to make sure discharge pressure doesn’t exceed 2,070
kPa (300 psi).
(2) Tighten all compressor mounting bolts, clutch mounting
bolt, and compressor drive belt. Check to assure clutch coilis tight (no rotation or wobble).
(3) Check refrigerant hoses for rubbing or interference that cancause unusual noises.
(4) Check refrigerant charge (See “Charging the System”).
(5) Recheck compressor noise as in Step 1.
(6) If noise still exists, loosen compressor mounting bolts and
retorque. Repeat Step 1.
(7) If noise continues, replace compressor and repeat Step 1.
