3. INSPECT IDLE±UP SPEED
(a) Warm up engine.
(b) Inspect idle±up speed when the these conditions are es-
tablished.

Warm up engine

Blower speed control switch at ºHIº position

A/C switch ON

Temperature control dial at ºCOOLº position
Magnetic clutch conditionIdle±up speed
Magnetic clutch not engaged700 ± 50 rpm
Magnetic clutch engaged700 ± 50 rpm
If idle speed is not as specified, check ISC valve and air intake
system.
4. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Perform in these conditions:

Stop engine.

Secure good ventilation (If not the gas leak detector
may react to volatile gases witch are not refrigerant,
such as evaporated gasoline and exhaust gas.)

Repeat the test 2 or 3 times.

Make sure that there is some refrigerant remaining
in the refrigeration system.
When compressor is OFF: approx. 392 ± 588 kPa
(4 ± 6 kgf/ cm
2, 57 ± 85 psi)
(b) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:

After the blower motor stopped, leave the cooling unit for
more than 15 minutes.

Expose the gas leak detector sensor the under the drain
hose.

When bring the gas leak detector close to the drain hose,
make sure that the gas leak detector does not react to the
volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
blower resistor from the cooling unit. Then insert the gas
leak detector sensor into the unit and perform the test.
(d) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines
and perform the test.

INTRODUCTIONGENERAL REPAIR INSTRUCTIONS ±

GENERAL REPAIR INSTRUCTIONS
1. Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
2. During disassembly, keep parts in the appropriate order
to facilitate reassembly.
3. Observe the following:
(a) Before performing electrical work, disconnect the
negative (±) terminal cable from the battery.
(b) If it is necessary to disconnect the battery for inspec-
tion or repair, always disconnect the cable from the
negative (±) terminal which is grounded to the ve-
hicle body.
(c) To prevent damage to the battery terminal post, loos-
en the terminal nut and raise the cable straight up
without twisting or prying it.
(d) Clean the battery terminal posts and cable terminals
with a clean shop rag. Do not scrape them with a file
or other abrasive objects.
(e) Install the cable terminal to the battery post with the
nut loose, and tighten the nut after installation. Do
not use a hammer to tap the terminal onto the post.
(f) Be sure the cover for the positive (+) terminal is prop-
erly in place.
4. Check hose and wiring connectors to make sure that they
are secure and correct.
5. Non±reusable parts
(a) Always replace cotter pins, gaskets, O±rings and oil
seals etc. with new ones.
(b) Non±reusable parts are indicated in the component
illustrations by the ºº symbol.
6. Precoated parts
Precoated parts are bolts and nuts, etc. that are coated
with a seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(b) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then applyIN022±07
