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 first sign of a failing A/C compressor is typically a reduction in cooling performance, with the air not getting as cold as usual. This can progress to intermittent cooling or complete loss of cooling, accompanied by potential whining or grinding noises from the compressor. A severely failed compressor can lead to system blockage and costly repairs.

Installation Tip

Always flush the A/C system thoroughly to remove debris and old oil before installing a new compressor. Ensure the correct type and amount of refrigerant oil is added to the new compressor before connection.

Service Note

Replace the receiver-drier or accumulator and inspect the expansion valve or orifice tube when replacing the A/C compressor.
