ON-VEHICLE SERVICE
SERVICE PRECAUTION
When servicing air conditioning system, note the following instructions.
REFRIGERANT LINE
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
Tighten flared nuts by the following specified torque.
Tightening torque
8 mm pipe : 13 N·m (1.3 kg-m, 9.5 lb-ft)
12 mm pipe : 23 N·m (2.3 kg-m, 16.6 lb-ft)
14.5 mm pipe : 33 N·m (3.3 kg-m, 23.8 lb-ft) WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
 Do not use your hand to rub affected eye(s). Instead, use quantities of fresh cold water to splash it
over affected area to thus gradually raise its temperature above the freezing point.
 Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refriger-
ant HFC-134a (R-134a) get on your skin, such affected part should be treated in the same manner as
when skin is frostbitten or frozen.
1. Suction hose:
Apply compressor oil (refrigerant oil) to O-ring.4. Expansion valve:

ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indi-
cator of the condition of the engine. The vacuum checking proce-
dure is as follows :
1) Warm up engine to normal operating temperature.
2) Stop engine and turn off the all electric switches.
3) Remove cap (1) from intake manifold.
NOTE:
After warming up engine, be sure to place transmission
gear shift lever in “Neutral” (shift selector lever to “P”
range for A/T model), and set parking brake and block
drive wheels.
