2001 Es300 Air Conditioner Pressures

Recommended Posts

I tested my A/C high and low side pressures this past weekend.

With the outside temp around 75 degrees the high side was around 400 psi and the low side was around 52 psi.

The compressor never cycled on/off, and the pressures were steady.

These pressures seem to be excessive.

What are the normal pressures?
