BDFHYK 178313 A/C Compressor with Clutch For Ram 2500 3500 4500 5500 6.7L 2011-2023 Replacement 55111-444AB, RL111-444AB, R5111-444AB

BDFHYK 178313 A/C Compressor with Clutch for Ram 6.7L Diesel Trucks

If your Ram 2500, Ram 3500, Ram 4500, or Ram 5500 6.7L diesel is blowing warm air, cooling weakly at idle, making compressor or pulley noise, or showing A/C clutch engagement issues, this BDFHYK 178313 car AC compressor with clutch may be the replacement to consider after diagnosis. Before ordering, match the OE number, compressor body, ports, connector, clutch face, pulley area, and mounting points to the original unit.

Fitment Buyers Should Confirm

• Vehicle focus: selected Ram 2500, Ram 3500, Ram 4500, and Ram 5500 6.7L diesel applications.
• Additional OE-match coverage: selected Dodge Ram 2500 / 3500 / 4000 6.7L applications where the original compressor matches.
• OE / interchange references: 55111-444AB, RL111-444AB, RL111-44AB, R5111-444AB, 178313.
• Physical match: compare compressor body, clutch face, pulley area, refrigerant ports, electrical connector, and mounting points.

Why This Ram Diesel Compressor Fits the Buyer Need

• A/C compressor with clutch: suitable when the compressor and clutch assembly are replaced together.
• Heavy-duty truck use: built around common buyer concerns such as towing, long idle time, hot-weather routes, and high-mileage A/C service.
• Wrong-part prevention: Ram diesel trucks can vary by year and chassis, so OE number and physical layout matter more than model name alone.
• OE-style aftermarket replacement: designed as a replacement option after compressor or clutch failure is confirmed.

Common Symptoms to Inspect Before Replacement

• Warm air from vents: may involve compressor wear, refrigerant loss, leaks, pressure controls, or wiring.
• Weak cooling at idle or while towing: may involve condenser airflow, fan operation, refrigerant charge, restriction, or compressor output.
• Compressor or pulley noise: may come from pulley bearing wear, clutch drag, belt drive issues, or internal compressor damage.
• Clutch not engaging: may involve low-pressure protection, fuse, relay, wiring, clutch coil, or compressor failure.

A new vehicle AC compressor can only help when compressor or clutch failure is confirmed. If the old compressor failed internally, ask the installer whether condenser, drier or accumulator, expansion device, hoses, and flushing should be handled during service. This is an OE-style aftermarket replacement, not a Genuine OEM or Official OEM part.
