FAQs

Does this compressor come with oil?

Yes, it arrives pre-filled with 200ml of ND-8 oil.

Is this compatible with R12 refrigerant?

No, this compressor is specifically designed for use with R 134a refrigerant.

How do I verify if this fits my car?

Check your existing compressor or vehicle service manual to see if it matches OE part number 504014391.

What is the pulley diameter?

The pulley diameter is 110mm with a 4-groove design.

Do I need to replace other parts when installing this?

It is highly recommended to replace the receiver drier and expansion valve to prevent debris from the old system from damaging the new unit.

Troubleshooting

Compressor clutch fails to engage

Check the 12V power supply to the clutch connector and verify the A/C relay and pressure switch functions.

Excessive noise during operation

Inspect the belt tension and alignment of the 4-groove pulley to ensure it is perfectly square with the drive system.

Poor cooling performance shortly after install

Verify refrigerant charge levels according to vehicle manufacturer specifications and ensure the system was properly vacuumed to remove air.

Pros and Cons

Pros

  • Genuine OE build quality and durability
  • Pre-filled with correct oil volume for time-saving installation
  • Reliable magnetic clutch assembly
  • Meets rigorous factory performance standards

Cons

  • Requires precise verification of OE part number 504014391
  • System flushing may be required upon installation to prevent contamination
  • Installation requires specialized A/C evacuation equipment

Setup, Compatibility & Care

Proper installation is critical to the lifespan of this compressor. Always verify that your vehicle's OE part number matches 504014391. During setup, ensure that the A/C system is properly evacuated and flushed of debris from the old, failed compressor. Failure to flush the system can contaminate the new ND-8 oil and lead to immediate pump failure. The unit uses a standard bolt-on mounting style. We recommend replacing the receiver drier and expansion valve simultaneously to ensure the system remains clean and moisture-free, which protects the internal seals of the new compressor.
