Technical Information

What you need to know

If you’re replacing an A/C Compressor, you have to be prepared to replace additional components in the system depending on the reason why your own compressor failed. The information provided below was made to help you save TIME and MONEY.

1.) Compressor locked/seized internally:

If your compressor seized internally it was due to insufficient refrigerant or oil in the system or the system was blocked, leading to overheating of the compressor which caused a breakdown of internal parts.

Visible symptoms:

The oil in the compressor is black and/or has aluminum particles in it. The belt snapped or when the a/c is turned on, the engine feels like it’s going to turn off.

What you should do:

1. Replace the A/C Compressor (make sure to add PAG Oil)

2. Replace the Receiver Drier/Accumulator

3. Replace the Expansion Valve/Orifice tube

4. Flushing the a/c lines, condenser and evaporator is REQUIRED (We professionally recommend to replace the condenser on modern vehicles since the passage on the fins are so small that a flush will not remove all contaminants).

5. Vacuum the system for 30 – 45 minutes. This will remove any moisture in the system.

6. Add the correct amount of refrigerant to the system.

7. Run vehicle on lowest fan setting for about 3 minutes to allow the compressor to cycle the refrigerant and oil.

The reason why it’s important to replace the additional parts listed is because if you add a new compressor to acontaminated system, the compressor will cycle the contaminants and will eventually lock up again.
