NOTICE: An Air Conditioning (A/C) refrigerant analyzer must be used before
the recovery of any vehicle's A/C refrigerant. Failure to do so puts the shop's
bulk refrigerant at risk of contamination. If the vehicle's A/C refrigerant is contaminated,
refer the customer to the service facility that carried out the last A/C service.
If the customer wishes to pay the additional cost, use the A/C recovery equipment
that is designated for recovering contaminated A/C refrigerant. All contaminated
A/C refrigerant must be disposed of as hazardous waste. For all equipment, follow
the equipment manufacturer's procedures and instructions.
NOTICE: On vehicles being serviced for an internal compressor or desiccant
failure, a new suction accumulator or receiver/drier, Thermostatic Expansion Valve
(TXV) or evaporator core orifice and any hoses containing mufflers must be installed
prior to filtering the Air Conditioning (A/C) system. Internal plumbing of these
devices makes it impossible to correctly remove any foreign material. These components
are typically discarded after A/C system contamination. Hoses without mufflers can
normally be reused unless they are clogged with foreign material. The filter is
intended for use on one vehicle only.
- NOTE:
The filter inlet is marked with a label on one side of the
filter body.
Orient the filter inlet toward the A/C condenser core.
- NOTICE: The flexible extension adapters included in the A/C Flush Adapter
Kit are designed for low-pressure flushing and are not designed for use with
a charged refrigerant system. Do not make the condenser fitting connections
using the flexible extension adapters or damage to the adapters and loss of
refrigerant will occur.
NOTE:
The F8VZ-19E773-AB pancake filter is not permanently installed
and will be removed at the end of this procedure.
Disconnect the condenser outlet fitting and temporarily install the pancake
filter between the 2 halves of the fitting.
- Use flexible R-134a service hoses of 17,238 kPa (2,500 psi) burst rating.
- Make the connections using the correct adapters from the A/C Flush Adapter
Kit and/or A/C Flush and Purge Fitting Kit.
- Lubricate the refrigerant system with the correct amount of clean PAG oil.
For additional information, refer to Refrigerant Oil Adding in this section.
- Evacuate and charge the refrigerant system. For additional information,
refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in
this section.
- Check all refrigerant system hoses, lines and the position of the newly
installed filters to be sure they do not interfere with other engine compartment
components. If necessary, use tie straps to make adjustments.
- Provide adequate airflow to the front of the vehicle (with a fan, if necessary).
Select A/C operation and set the blower motor speed to maximum. Start the engine
and let it idle briefly. Make sure the A/C system is operating correctly.
- Using a scan tool, command the idle to gradually bring the engine up to
1,200 rpm by running it at lower rpms for short periods (first at 800 rpm, then
at 1,000 rpm). Set the engine at 1,200 rpm and run it for one hour with the
A/C system operating.
- Stop the engine.
- Recover the refrigerant. For additional information, refer to Air Conditioning
(A/C) System Recovery, Evacuation and Charging in this section.
- Remove the adapters, flexible hoses and pancake filter from between the
condenser and the condenser to evaporator tube.
- Discard the pancake filter. It can be used one time only.
- Reconnect the condenser outlet fitting.
- Evacuate, charge and leak-test the refrigerant system. For additional information,
refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging in
this section.
