Folks-

Last night I recharged my partially empty system using straight R134A - no stop leak or oil or anything else. Took in about 18 oz and the compressor kicked on and the system seems to be functioning correctly (until it leaks out again)....that will be the next project I am sure...however I wanted to confirm correct operation of the system components.

That being said, here is the reason for my post:

I have the following readings with the car idling and ac on max:

low = 35
high = 175

temp last nite was probably around 75 when I did this.

are these numbers acceptable?

The reason I ask is that when the system is running I am hearing a strange noise coming from under the hood when i rev it up in park. It is definitely something AC related as it does not exist with the AC off.

I was thinking that maybe I overcharged it or something, however, the numbers I currently have do not seem to be out of the "normal" range.

Any helpful insight most appreciated.

Regards

It sounds like you may have a problem with the A/C compressor. It makes sense that with the A/C turned off, it makes no noise....the A/C clutch disengages and stops the noise. It's certainly not uncommon for a compressor to go bad. It is, after all, the one component of the system with the most amount of moving parts and stress. Maybe the pistons inside the compressor are going bad? Or maybe the clutch is slipping when engaged?
