Repairing AC

It's early summer in Houston and the AC in my Box is marginal. At 85 F ambient the low side is 40 psi and the high side is 225 psi. Add R134A and the low side goes to 50 and the high side goes to 230. I plan to replace the compressor, dryer, and expansion valve. The condensers are cleaned out and the belt is new. Does anyone have the low and high side numbers? Any tips or tricks on getting it running in top shape? Houston is about a mile from the sun in mid summer so marginal AC is not an option.

Both air condition system pressures are dependent upon the ambient temperature. You need to locate the correct table Porsche published for your year and model to determine where you need to be.

The Mosquitoes don't think so. I saw one happily carrying away a slightly deflated Labrador Retriever just this morning.

Yes, that was is what I'm looking for. Any idea where they can be found? And yes, I did search the forum.

The only palace that I know it exists in in the factory service manuals.
