I measured the larger pipe on the left side of the compressor as mounted and measured 210-220F while running for a few minutes after my drive home.

The high pressure line at the service port measured 150-160F.

Maybe it’s louder because I went with aftermarket, but I really don’t want to damage it further. I was thinking today that I could ask my shop to evacuate and recharge me. Maybe they have a way of separating any oil in the system to ensure I have enough? I did refill the compressor with ~3.5-4.0 oz of PAG46 oil and tried to load another 1oz in the fill line before filling, but that didn’t work well.

 

Hi Club,

I don’t see the troubleshooting guide in this thread. Could you tell me how to find it?

 

Does the AC work OK? As you said it's a different brand of compressor and maybe they do run a bit noisier than you were use too?
Just guessing as I did not see if you had said how the AC is working.

Yes, the AC works great! I just can tell when the compressor is engaged as it saps power from the engine then there is the audible spooling noise that follows the engine rpm (turns off when AC if off). This makes me hesitant to keep running it if it will damage the compressor. Only thought I had since I don’t want to start over is to pay for a recharge at my local auto shop. May do nothing as well. Thanks as always!

 

I am sorry Griff! I tried several times to upload it but the forum can't handle the file size. I tried to send it to your E-mail but same thing?

But I have uploaded it to here;
Jaguar AC Troubleshooting Guide

As always this is a link from some guy on the internet! This link should be good for 30 days I "think"?
Note it's about 35 MB in size.

Thanks club!

I have downloaded it and will use it as a reference! After a few more days of driving, I am feeling more confident in the compressor, and the cold air really feels good. I’ll let you know when I knock out the serpentine belt and whether that helps anything. I have the spark plugs ready for a weekend later this year.

Cheers!

 

Good news as I was not sure you had a problem?

Have fun changing the plugs too!

So I'm having a ac problem now suddenly in my XJ. I'm guessing it's the DPS but I'll verify. Is it still the easiest to just replace the whole compressor? Or go with the DPS (I see it for sale for $100 or so)

 

Considering the amount of labor is about the same, I would recommend you replace the compressor (don’t have to buy OEM if you don’t want to). You don’t want to have to be back in a year doing the same job! clubairth1 would know what a pain that is!

 

I did just that and yes I had to go back in and finally just replaced the entire compressor with DPS valve with one that had a warranty. That was months ago and it's now in the 95+ degree time of the year here and it's blowing ice cold.

Are the symptoms of a bad valve and a bad compressor the same? I heard that a bad valve means high pressure on the low pressure line
