A/C Service Tips and Precautions

The air
conditioner system uses
HFC-134a
(R-134a)
refrigerant
and
polyalkyleneglycol (PAG) refrigerant
oil*,
which
are not

compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do

not attempt to use R-12 servicing equipment; damage to the air conditioner system or your servicing equipment will result.

*DENSO ND-OIL 8:

P/N 38897 - PR7 - A01AH: 120 (4 fl-oz, 4.2 Imp-oz)

P/N 38899 - PR7 - A01: 40 (1 1/3 fl-oz, 1.4 Imp-oz)

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a

from the air conditioner system.

CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or mist can irritate eyes, nose and throat. Avoid

breathing the air conditioner refrigerant and lubricant vapor or mist.

If accidental system discharge occurs, ventilate work area before resuming service.

R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed

air.

Some mixtures of air and R-134a have been shown to be combustible at elevated pressures and can result

in tire or explosion causing injury or property damage. Never use compressed air to pressure test R-134a service equip-

ment or vehicle air conditioner systems.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.

2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't

remove the caps or plugs until just before you reconnect each line.

3. Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.

4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.

5. When discharging the system, use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refriger-

ant into the atmosphere.

6. Add refrigerant oil after replacing the following parts:

NOTE:

To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-

ant oils.

Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.

Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash

it off immediately.

Compressor ................................ For compressor replacement, subtract the volume of oil drained from the

removed compressor from 140 (4 1/3 fl-oz, 4.9 Imp-oz), and drain the calculated

volume of oil from the new compressor: 140 (4 1/3 fl-oz, 4.9 Imp-oz) — Volume

of removed compressor = Volume to drain from new compressor.

NOTE: Even if no oil is drained from the removed compressor, don't drain more

than 50 (1 2/3 fl-oz, 1.8 Imp-oz) from the new compressor.

Check for Wear and Damage

The starter should crank the engine smoothly and steadily.

If the starter engages, but cranks the engine erratically,

remove it, and inspect the starter drive gear and torque

converter ring gear for damage.

• Check the drive gear overrunning clutch for binding

or slipping when the armature is rotated with the

drive gear held. If the clutch is damaged, replace the

clutch assembly.

Check Cranking Voltage and Current Draw

Cranking voltage should be no less than 8.0 volts.

Current draw should be no more than 450 amperes.

If cranking voltage is too low, or current draw too high,

check for:

Dead or low battery

Open circuit in starter armature commutator segments

Starter armature dragging

Shorted armature winding

Excessive drag in engine

Check Cranking rpm

Engine speed during cranking should be above 100 rpm.

If speed is too low, check for:

Loose battery or starter terminals

Excessively worn starter brushes

Open circuit in commutator segments

Dirty or damaged helical spline or drive gear

Defective drive gear overrunning clutch

Check Starter Disengagement

With the shift lever in or , turn the ignition switch to

"START (III)", and release to "ON (II)". The starter drive

gear should disengage from the flywheel ring gear when

you release the key.

If the drive gear hangs upon the flywheel ring gear, check

for:

• Solenoid plunger and switch malfunction

• Dirty drive gear assembly or damaged overrunning

Starter Solenoid Test

1. Make sure you have the anti-theft code for the

radio, then write down the frequencies for the

radio's preset buttons.

2. Disconnect the battery negative cable, then discon-

nect the positive cable.

3. Check the hold-in coil for continuity between the S

terminal and the armature housing (ground). The

coil is OK if there is continuity.

4. Check the pull-in coil for continuity between the S and

M terminals. The coil is OK if there is continuity.
