CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using refrigerant HFC-134a (R-134a) and the other using refrigerant CFC-12 (R-12).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to “Refrigerant Type” in this section.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
NOTE:
For basic servicing method of the air conditioning system that is not described in this section, refer to
AIR CONDITIONING BASIC MANUAL (Part number: 99520-02130).

Check belt tension by measuring how much it deflects when
pushed at intermediate point between compressor pulley (1)
and crankshaft pulley (2) with about 100 N (10 kg, 22 lb)
force.
If belt tension is out of above specification, adjust belt ten-
sion according to the following procedures.
Deflection of compressor drive belt
“a” : 6 – 9 mm (0.24 – 0.35 in.)

Downloaded from www.Manualslib.com manuals search engine 1B-24 AIR CONDITIONING (OPTIONAL)
1) Connect high charging hose (1) and low charging hose (2) of
manifold gauge set (3) respectively as follows:
High charging hose (1) → High pressure charging valve (4)
on discharge hose
Low charging hose (2) → Low pressure charging valve (5) on
suction hose
2) Attach center charging hose (6) of manifold gauge set (3) to
vacuum pump (7).
3) Operate vacuum pump (7), and then open discharge side
valve (Hi) (8) of manifold gauge set (3).
If there is no blockage in the system, there will be an indica-
tion on high pressure gauge (9).
In this case, open the other side valve (Lo) (10) of the set
and repair the system.
4) Approximately 10 minutes later, low pressure gauge (11)
should show a vacuum lower than –760 mmHg providing no
leakage exists.
5) Evacuation should be carried out for a total of at least 15
minutes.
6) Continue evacuation until low pressure gauge (9) indicates a
vacuum less than –760 mmHg, and then close both valves
(8), (10).
7) Stop vacuum pump (7). Disconnect center charging hose (6)
from pump inlet. Now, the system is ready for charging refrig-
erant. NOTE:
If the system does not show a vacuum below –760
mmHg, close both valves, stop vacuum pump and
watch movement of low pressure gauge.
Increase in the gauge reading suggests existence of
leakage. In this case, repair the system before continu-
ing its evacuation.
If the gauge shows a stable reading (suggesting no
leakage), continue evacuation.

2) Connect Low charging hose (1) and High charging hose (2)
of the manifold gauge set (3) in position. Thus open refriger-
ant container valve (4) to purge the charging line.
3) Open the high pressure side valve (5) and charge refrigerant
to system.
4) After a while, open the low pressure side valve (6) and close
the high pressure side valve (5).
5) Start engine and keep engine speed at 1500 r/min. Then,
operate air conditioning.
6) Charge A/C system with refrigerant in vapor state. At this
time, refrigerant container should be held upright.
7) When refrigerant container (3) is emptied, use the following
procedure to replace refrigerant container with a new refrig-
erant container (3).
a) Close low pressure valve.
b) Replace empty container (3) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (4), use the following proce-
dure for replacement.
i) Retract needle (1) and remove refrigerant container tap
valve (4) by loosening its plate nut (2).
ii) Install previously-removed refrigerant container tap valve
(4) to a new refrigerant container (3).
c) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the follow-
ing procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and
then loosen (open) plate nut (2) slightly.
ii) Open low pressure side valve (3) of manifold gauge set
(4) a little.
iii) As soon as refrigerant comes out with a “hiss” through a
clearance between refrigerant container and tap valve,
tighten plate nut (2) as well as low pressure side valve (3).
iv) Turn handle of tap valve (1) clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow. WARNING:
Make sure that high pressure side valve is closed
securely.
