REPLACEMENT
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).
Standard: 440 30 g (15.51 1.06 oz.)
SST 07110±58060 (07117±58060, 07117±58070, 07117±58080, 07117±58090, 07117±78050, 07117±88060, 07117±88070, 07117±88080)
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.
