A/C Refrigerant/Oil - Capacity Revisions

NO: 24-19-96

GROUP: Air Conditioning

DATE: Nov. 22, 1996

SUBJECT:
A/C Performance

MODELS:
1995 - 1997 (JA) Breeze/Cirrus/Stratus

DISCUSSION:

The type and quantity of refrigerant oil used in JA vehicles has been changed to enhance performance. The oil capacity of the total air conditioning system has been reduced to 5.0 ft. oz. (150 ml.) from 7.0 fl.oz. The oil designated for JA vehicles is SP-15 PAG (revised from SP-10), P/N 04886129AA.

Following procedures/guidelines will maximize A/C system performance during routine service and diagnosing complaints of poor A/C performance.

System Refrigerant Charge:

^ 1995-1996 vehicles, charge to 28 fl.oz.

^ 1997 vehicles, charge to 26 fl.oz.

^ All vehicles: To obtain the proper system refrigerant charge level using reclaim/recycling equipment, add an additional 2 fl.oz. of refrigerant per charging hose to account for charging hose capacity. Reference SUN STAND owners manual section "USING THE AUTO SEQUENCE FEATURE" (or equivalent).

^ The recommended procedure to check charge level is the "Partial Charge Test" (using the DRB III and a thermocouple).

System Oil Level:

^ For vehicles built before April 1, 1996 (MDH 04-01-XX), remove 2.0 fl.oz. of oil from compressor.

^ For vehicle built after April 1, 1996 (MDH 04-01-XX), do not remove 2.0 fl.oz. of oil from compressor.

^ During routine service, use only SP-15 PAG refrigerant oil, Mopar P/N 04886129AA.

2.5L Engine Equipped Vehicles:

^ TSB 24-07-96 Rev. A should be performed on all 2.5L equipped vehicles with A/C performance complaints.
