Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most common initial sign of a failing AC compressor is a significant decrease in cooling performance, with air from the vents becoming warm. If left unaddressed, the compressor may begin to make loud, grinding noises, and eventually cease to function entirely, leading to a complete loss of air conditioning. Continued operation with a failing compressor can potentially damage other components within the AC system.

Installation Tip

Before installing, ensure the AC system is properly evacuated and flushed to remove any debris or contaminants that could damage the new compressor. Avoid over-tightening the mounting bolts, as this can distort the compressor housing.

Service Note

Inspect the AC system's receiver-drier and expansion valve for signs of contamination or blockage when replacing the compressor.
