(7) When there is air in the refrigeration system:
SymptomProbable causeDiagnosisCorrective Actions

Pressure is extreamly high on
both low and the high pressure
sides

The low pressure piping is too
hot to touch

Air in refrigeration system

There is air in refrigeration sys-
tem

Vacuuming is insufficient
(1) Check it compressor oil is dirty
or insufficient
(2) Vacuum and supply new refrig-
erant
(8) When the expansion valve malfunctions:
SymptomProbable causeDiagnosisCorrective Actions

Pressure is extreamly high on
both low and high pressure sides

Frost or dew is on piping on low
pressure side
Trouble with expansion valve

Excessive refrigerant in low
pressure piping

Expansion valve opened too
wide
Replace expansion valve

INSPECT REFRIGERANT VOLUME
(a) This is a method to specify the trouble area by using a
manifold gauge set. Read the the manifold gauge pres-
sure when these conditions are established.
Test conditions:

Engine is at idle.

Blower speed control switch is at ºHIº.

Temperature control dial is at ºMAX. COOLº.

Engine has been warmed up.

All doors are fully open.

Hood is fully open.

Air inlet mode selector damper is at RECIRE.

Air outlet damper is at FACE.

Outside temperature is 15 ± 35
C (59± 95

F).
(b) Check refrigerant volume according to the graph below.

1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Turn the A/C switch ON.
(b) Operate the cooler compressor at the engine rpm of approx. 1,000 for 5 to 6 min\
uites to circulate the refrigerant and collect the compressor oil remaining in each component into the cooler compresso\
r as
much as possible.
(c) Shut off the engine.
(d) Let the refrigerant gas out.

2. CHARGE REFRIGERANT
(a) Using a vacuum pump, perform vacuuming.
(b) Charge refrigerant, HFC±134a (R134a).

3. WARM UP ENGINE
4. INSPECT LEAKAGE OF REFRIGERANT
(a) Using a gas leak detector, check for leakage of the refrigerant.
NOTICE:
1CD±FTV Hot gas heater:
Since the system uses a refrigerant filter (fixed valve), sound of the refr\
igerant circulation (hissing
sound) can be heard for approx. 30 seconds after turning the A/C off. T\
his is merely a sound of bal-
ancing the low pressure with the high pressure, not a sound of abnormality.

3. REMOVE ENGINE UNDER COVER RH 4. REMOVE V (COOLER COMPRESSOR TOCRANKSHAFT PULLEY) BELT NO.1
(a) Loosen the nut A.
(b) Loosen the bolt B and remove the V (cooler compressor to crankshaft pulley) belt No. 1.
5. INSTALL V (COOLER COMPRESSOR TO CRANKSHAFT PULLEY) BELT NO.1
(a) Temporarily install a new V (cooler compressor to crank- shaft pulley) belt No. 1 as shown in the illustration.
6. ADJUST V (COOLER COMPRESSOR TO CRANKSHAFT PULLEY) BELT NO.1
(a) Tighten the nut A. Torque: 2.5 N

(b) Apply drive belt tension by turning bolt B. Belt deflection:
New belt: 11 ± 13 mm (0.43 ± 0.51 in.)
Used belt: 13.5 ± 16.5 mm (0.53 ± 0.64 in.)
HINT:

The new belt refers to a belt which is used for less than
5 minutes on the running engine.

The used belt refers to a belt which is used for 5 minutes,
or more on the running engine.

After installing the drive belt, check that the belt fits prop-
erly in the ribbed grooves.

Check that the drive belt does not slip off the groove at the
end of the pulley by hand.
