What It Helps Fix

• No cold air from the vents
• Compressor clutch engagement problems
• High-pressure switch-related A/C shutdowns
• Noise or wear from a failing HT6 compressor
• Refrigerant circulation loss in R134a systems

Installation Notes and Tips

Verify the vehicle uses an HT6 compressor with a premium clutch setup before ordering. Use PAG 46 compressor oil as specified in the fitment notes, and confirm the 6-groove serpentine pulley, tangent mount layout, and sealing-washer port style match the original unit. Mounting hardware is not included.

For best results, replace the receiver-drier or accumulator, evacuate the system, and recharge to the correct specification after installation. Check belt alignment and electrical connector fitment before starting the engine.

Quality Assurance

This is a new compressor, not a remanufactured unit. It is built for direct replacement service in confirmed GM HT6 applications and is listed with included oil, clutch, and high-pressure switch details for accurate parts matching.
