Climate Control: Removal & Installation Honda Insight ZE2 рестайлинг

Receiver/Dryer Desiccant Replacement

Note. Install the receiver/dryer as quickly as possible to prevent the system from absorbing moisture from the air.

Scheme 60

1. Remove the A/C condenser (see «A/C CONDENSER REPLACEMENT»(ref-513164-S10873802182012110700000) ).
2. Remove the cap (A) from the bottom of the A/C condenser. Remove the O-ring (B) and the desiccant (C).
3. Install the receiver/dryer in the reverse order of removal, and note these items: Replace the O-rings with new ones, and apply a thin coat of refrigerant oil (SP-10) before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage. Install the cap to the specified torque. It is made of resin and can be easily stripped.

A/C Compressor Replacement

Note. Do not install an A/C compressor into a system unless you are completely sure that the system is free of contamination. Installing the A/C compressor into a contaminated system can result in premature A/C compressor failure.

Scheme 61

Scheme 62

1. If the A/C compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.
2. Recover the refrigerant with a recovery/recycling/charging station (see «REFRIGERANT RECOVERY»(ref-513164-S08783319812012110700000) ).
3. Raise the vehicle on the lift.

5. Remove the drive belt (see «DRIVE BELT REPLACEMENT»(ref-513159-S05522561372012110700000) ).
6. Remove the compressor clutch connector (A) from the condenser fan shroud, then disconnect the connector. Remove the bolts, then disconnect the suction line (B) and the discharge line (C) from the compressor, and remove the O-rings (D). Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
7. Remove the mounting bolts, and remove the A/C compressor from underneath the vehicle. Be careful not to damage the radiator fins when removing the A/C compressor. Do not drop the A/C compressor.
8. Install the compressor in the reverse order of removal, and note these items: Before installing a new A/C compressor, adjust the compressor oil level (see «A/C REFRIGERANT OIL REPLACEMENT»(ref-513164-S26683920502012110700000) ). Inspect the A/C lines for any signs of contamination. Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage. Use refrigerant oil (SP-10) for HFC-134a SANDEN spiral type A/C compressor only. To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils. Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption. Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately. Charge the system (see «SYSTEM CHARGING»(ref-513164-S07296478792012110700000) ).
9. Lower the vehicle on the lift.

A/C Compressor Relief Valve Replacement

Note. If the A/C compressor relief valve released refrigerant to the atmosphere, determine and correct the cause of the excessive system pressure, then replace the relief valve.

Scheme 63

1. Recover the refrigerant with a recovery/recycling/charging station (see «REFRIGERANT RECOVERY»(ref-513164-S08783319812012110700000) ).
2. Remove the relief valve cover (A), the relief valve (B), and the O-ring (C). Plug the opening to keep foreign matter from entering the system and the A/C compressor oil from running out.
3. Clean the mating surfaces.
4. Replace the O-ring with a new one at the relief valve, and apply a thin coat of refrigerant oil before installing it.
5. Remove the plug, and install and tighten the relief valve.
6. Charge the system (see «SYSTEM CHARGING»(ref-513164-S07296478792012110700000) ).

Scheme 64

Scheme 65

3. Install the thermal protector in the reverse order of removal.

A/C Refrigerant Oil Replacement

Special Tools Required

Oil Injector Tool Robinair ROBI 6256, commercially available

*This tool is available through the Honda Tool and Equipment Program; call 888-424-6857

Recommended PAG oil: SP-10

1. P/N 38897-P13-A01AH: 120 mL (4 fl.oz)

It is important to have the correct amount of refrigerant oil in the A/C system to ensure proper lubrication of the A/C compressor.

Too little oil damages the A/C compressor; too much oil reduces the cooling capacity of the system, and can produce high vent temperatures.

1. To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
2. Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
3. Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off immediately.

Add the recommended refrigerant oil in the amount listed if you replace any of the following parts.

A/C condenser (including dryer desiccant)..................25 mL (5/6 fl.oz)

Evaporator................35 mL (1 1/6 fl.oz)

Line or hose..............10 mL (1/3 fl.oz)

Dryer desiccant.........10 mL (1/3 fl.oz)

Leakage repair..........25 mL (5/6 fl.oz)

A/C compressor........Since the oil separator is equipped inside the compressor for this vehicle, oil drainage is unnecessary at the time of compressor replacement.
