Youxmoto AC Compressor with Clutch HT6 for GM 5.7L Vehicles — Prefilled PAG46, 126mm 6-Groove Pulley

This Youxmoto AC compressor with clutch is a direct-replacement HT6 unit prefilled with 180ml PAG46 oil, built to restore air-conditioning performance on compatible Cadillac, Chevrolet and GMC trucks and SUVs from the mid‑1990s to 2000.

If your factory air conditioning has lost cooling power, seized or makes unusual noise, replacing the compressor with a correct-fit unit is often the fastest way to recover cold airflow. This Youxmoto compressor is engineered for vehicles that used the HT6-style compressor and fits a long list of 4.3L, 5.0L, 5.7L, 6.5L and 7.4L engines across Escalade, Silverado, Suburban, Tahoe, Yukon, C/K series trucks and several other GM-platform models from roughly 1995–2000.

How does this compressor affect performance and efficiency?

The compressor is built for steady operation with low audible noise and a design intended to reduce drag on the engine. Under normal load it helps maintain efficient A/C operation and can contribute to smoother system cycling, which helps comfort and may modestly reduce accessory load at highway speeds.

• Low-noise design for quieter cabin operation
• Engineered to run with standard HT6 system pressures and cycles
• Reduced mechanical drag under light loads to help fuel efficiency

What should I check before installing a replacement compressor?

Confirm compatibility by matching engine size, model year and existing compressor type; inspect the condenser, dryer/accumulator and expansion valve or orifice tube for contamination before installation. Replacing the compressor alone without addressing system contamination or incorrect oil charge may lead to premature failure.

• Verify vehicle year, make, model and engine; check original part number if available
• Flush the system or replace contaminated components (condenser, receiver/drier)
• Ensure correct refrigerant and oil volumes when recharging the system

Who is this for: This Youxmoto HT6 AC compressor with clutch is intended for DIY mechanics, independent shops and fleet technicians who need a reliable, direct-replacement compressor for mid‑1990s to 2000 GM trucks and SUVs. It’s best for vehicles that require an HT6-style unit and for owners who will verify fitment, replace contaminated components, and recharge the system to factory specifications.
