Youxmoto AC Compressor with Clutch — Direct Fit for 1996–2005 Chevy/GMC 4.3L–7.4L, Sanden SD7H15 Style, PAG46 Prefilled

A heavy-duty replacement A/C compressor with integrated clutch engineered to restore cold air performance for compatible Chevy, GMC and related 4.3L–7.4L vehicles. This Youxmoto compressor is a direct-fit Sanden SD7H15-style unit supplied prefilled with PAG 46 oil and designed for a wide range of late‑90s and early‑00s Chevrolet and GMC trucks and SUVs. It replaces several OEM numbers and includes the clutch assembly, so it addresses typical compressor failures without requiring a custom fabrication. Before installation, you should flush and dry the entire A/C system and transfer the high‑pressure switch from the old unit to prevent contamination and ensure correct system operation.

Which vehicles is this compressor compatible with?

This model fits numerous applications across Chevrolet and GMC vans, trucks and SUVs from the late 1990s to early 2000s. Confirm the engine displacement and year against your vehicle’s factory specifications before ordering to ensure fitment.

• Chevy Express and GMC Savana 1500/2500/3500 (1996–2000; selected 2001–2002 3500 entries)
• Chevrolet Blazer, S10, GMC Sonoma, Jimmy, Oldsmobile Bravada and Isuzu Hombre in listed years
• Compatible engines include 4.3L, 5.0L, 5.7L, 6.5L and 7.4L where specified

What technical specifications and preparations should I know before installation?

The compressor is based on the Sanden SD7H15 design (not the HT6 family), has a 110 mm pulley with six grooves and ships with 180 mL of PAG 46 oil. You must remove the high‑pressure switch from your old compressor and inspect the condenser, dryer and system for contamination prior to installing the new unit.

• Compressor type: Sanden SD7H15 (HT6 not compatible)
• Oil: PAG 46, prefilled 180 mL
• Pulley: 110 mm diameter, 6 grooves
• Important: flush system and ensure cleaner has fully evaporated before fitting

How does this replacement affect performance and efficiency?

The unit is built for steady operation with low noise output and efficient load handling, helping the A/C maintain consistent cooling while minimizing additional engine drag. Because it was engineered to cycle smoothly, it can reduce electrical and mechanical stress compared with a worn compressor, which can indirectly improve fuel economy under certain driving conditions.

• Designed for quieter operation and smoother clutch engagement
• Efficient under lower load to reduce power draw at higher speeds
• Helps return cooling capacity to factory‑like levels when system properly serviced

Which part numbers does it replace, and what installation tips should I follow?

This Youxmoto compressor replaces several OEM references—verify cross‑numbers with your VIN or existing part to confirm accuracy. During installation, clean the system thoroughly, replace the receiver/dryer or accumulator, and ensure the high‑pressure switch is transferred and torque specs are followed.

• Common replacement numbers include CO 4261, 031852S and 5512124
• Recommended: flush lines, replace dryer/accumulator, evacuate and recharge by spec
• Transfer the high‑pressure switch from the old compressor before fitting

Who is this for? This compressor is intended for DIY mechanics and professional technicians restoring air conditioning to late‑1990s and early‑2000s Chevy and GMC vans, trucks and SUVs where the Sanden SD7H15 pattern is required. It's useful when the original compressor has failed, is noisy, seizing, or no longer providing sufficient cooling—provided the rest of the A/C system has been inspected, cleaned and prepared for replacement components. If you need a direct replacement with standard OEM cross‑references and clear prefill oil, this unit delivers a straightforward swap when paired with proper system service.
