Product Details

Four Seasons 58950 is a new GM A/C compressor built for vehicles that require an HT6 compressor with a serpentine belt drive. The unit uses a 5.000-inch clutch maximum diameter, 127.000 mm pulley diameter, and 0.875-inch belt width, with a 12V coil and pressure switch setup. It is listed for a wide range of 1996-2000 Chevrolet and GMC trucks and SUVs, plus select Cadillac Escalade, Chevrolet Blazer, S10, GMC Jimmy, Sonoma, Oldsmobile Bravada, and Isuzu Hombre applications. The Four Seasons New Compressor line focuses on direct-fit replacement components for common OE-style HVAC service needs.

What This Compressor Helps Address

• No cold air from a failed A/C compressor
• Compressor noise, seizure, or internal wear
• Loss of refrigerant circulation in R134a systems
• Clutch engagement problems tied to compressor failure
• High-pressure switch-related A/C system faults

Installation Notes and Tips

Use PAG 150 compressor oil as specified for this application and verify the system is set up for R134a refrigerant before installation. Confirm the vehicle uses an HT6 compressor, tangent mount configuration, and serpentine belt drive before ordering. Mounting hardware is not included, so reuse or source the required hardware separately. Replace sealing washers and inspect the rest of the A/C system for contamination, leaks, or debris before charging.

Quality Assurance

Four Seasons supplies replacement HVAC components for OE-style service applications, and this compressor is built as a new unit rather than a remanufactured part. Fitment is confirmed for select 1996-2000 Chevrolet, GMC, Cadillac, Oldsmobile, and Isuzu vehicles listed above.
