I charged up my Toyota Camry and got the compressor operating and then I over charged it and I had all the refrigerant and oil to blow out. Do I now need to remove the compressor and replace the pressure relief valve? Or can I replace the pressure relief valve while on the car? Also where do I get the correct valve for my car?

Wow! How did you charge it that you managed to blow the HPRV? Typically, the trinary switch in your Camry will shut-down the compressor before it reaches that critical high-pressure point.

The HPRV is a one-time valve, so you'll need to replace it.

The only place I'm aware of to purchase a new HPRV is at the Parts Department of your local Toyota dealer. Unsure whether you'll need to remove the compressor to access it. But be sure to bring the old one with you so that they can match it up.

OEM for your A/C system is Denso.
