NUMBER: 24-006-07GROUP: Heating & A/C
DATE: August 14, 2007
SUBJECT:
A/C Compressor Noise or Housing Damage
OVERVIEW:
This bulletin involves replacing the A/C Compressor with a new design and a new Condenser to compensate for revised compressor performance.
MODELS:
2007 (MK49) Compass
2007 (MK74) Patriot
2007 (PM) Caliber
NOTE:
This bulletin applies to 2007 PM/MK vehicles equipped air conditioning (sales code HHA or HAA) with a 1.8L, 2.0L or 2.4L (non turbo) Gasoline Engine (sales codes EBA, ECN or ED3) and Manual Transmission (sales codes DD7).
SYMPTOM/CONDITION:
A vehicle that is operated aggressively during cold conditions may experience damage to the A/C compressor due to refrigerant slugging causing poor or no A/C performance, possible rattle noise or compressor damage.
DIAGNOSIS:
Inspect the A/C compressor for physical damage to housing or rattle noise from compressor due to refrigerant slugging. If any of these symptoms exist, perform the Repair Procedure.
NOTE:
Whenever a compressor is damaged internally, the suction/liquid line (liquid line assembly) and accumulator must be replaced due to potential plugging from debris in the system.
PARTS REQUIRED:
NOTE:
The new compressor includes a 120 mm pulley and requires a new (longer) drive belt size of 2576 mm. (The old compressor has a 100 mm pulley with 2560 mm drive belt pn 04891598AB).
SPECIAL TOOLS/EQUIPMENT REQUIRED:
REPAIR PROCEDURE:
1. Following the procedures outlined in DealerCONNECT>TechCONNECT evacuate the A/C system.
2. Following the procedures outlined in DealerCONNECT>TechCONNECT, remove vehicle components to access and remove the A/C Compressor, Condenser, Liquid Line Assembly, and Accumulator.
3. Completely remove compressor drive belt from the vehicle and discard.
4. Flush and transfer the A/C Discharge Line (compressor to condenser) and A/C Suction Line (compressor to accumulator).
5. Following the specifications in DealerCONNECT>TechCONNECT, follow the oil fill requirements based on the components replaced and install the new Liquid/Suction Line pn 05058152AF, Accumulator pn 5189376AA, Condenser pn 68004052AB, and Compressor pn 55111 555AA.
6. Install new accessory drive belt pn 04891721AB
NOTE:
The new drive belt must be installed due to revised length to accommodate new pulley size.
7. Following the procedures outlined in DealerCONNECT>TechCONNECT, install any vehicle components that were removed during disassembly.
8. Following the procedures outlined in DealerCONNECT>TechCONNECT, evacuate and fill the A/C system with R134A following the under hood placard for system capacities.
NOTE:
Do not start the engine with the A/C system under a vacuum.
