Installation Notes and Tips

Verify refrigerant type, clutch diameter, belt type, and mounting style before installation. Confirm vehicle application by year, make, model, and engine/HVAC configuration, especially on Audi TT Quattro models with the S Series exclusion. Replace the compressor only after the system has been properly inspected, evacuated, and serviced according to OEM procedures.
