High-Pressure Flexible Hose
EJS000A8
REMOVAL
1.
Remove engine cover and air cleaner cover. Refer to
2.
Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3.
Remove air cleaner assembly, air duct and air inlet pipe. Refer to
4.
Remove mounting bolt and nut from the high-pressure flexible
hose, then remove it.
CAUTION:
Cap or wrap the open ends of the pipe with a suitable material
such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
●
Replace high-pressure flexible hose O-ring with a new one. Apply compressor oil prior to installa-
tion.
●
When pouring refrigerant, check for leaks.
