Question A/C Compressor Leaking OEM or After-Market Replacement?

The A/C compressor on my 2004 X-Type is leaking and the Jag dealer wants to replace it. It hasn't worked at peak performance for several years so I know they're not trying to pull something over on me. The question is if I get the OEM compressor it's $2,628. If I get an after-market product through the dealership it's $1,190 but there is no guarantee with it. Has anyone had any experience with an after-market A/C compressor? Is it worth the peace of mind to get the OEM?

I bought mine from Parts Geek to replace last fall, but ran out of time. Going to do it this summer. WAY,WAY less cost than your 2 amounts.
Compressor only, kit, and kit with condensor.

Is the actual A/C-compressor leaking (and if yes: How has that been determined?) or are there simply leaks in the of the connections to the A/C-compressor and in other seals of the A/C-system, which would be normally the case? Because, it it is just the seal, you can buy them very cheaply on various general online platforms (it is the green seals). Just buy a pack of all sizes of seal for A/C use.

The only A/C compressor I have swapped so far was on my van, and that was because it was seized.

Common fault with these compressors.

I wish I could give you an answer on that. When I took it to the dealer for some routine maintenance they said there was a massive leak in the A/C compressor, which I thought was odd because I am able to check the garage floor underneath the car frequently and there are no leaks from anything ever. Still, the air conditioner hasn't been at peak efficiency for several years.

I don't have the knowledge or the ability to work on my car (I'm a 76-year-old female). I just know enough to keep whatever needs to be maintained in good working order. Past that, I have to take it to a mechanic.

I guess maybe I'll try and find a local mechanic who can work on Jaguars. Good luck with that.🙄

I had that problem, a slow leak that didn't leak on the floor but none the less caused the compressor to fail over time. I replaced the compressor, condenser, dryer and orifice.

@ OneLovelyCar:

I just thought I should spell out the obvious: A leak in an A/C system (and that includes a possible leak in the compressor/compressor-area) means that the refrigerant gas (probably R135A) is escaping, i.e. there would not be a visible fluid leak visible under the car. Yes, the A/C-gas has also a tiny bit of A/C-oil mixed in, but I do not think that it is enough to ever see a leak of that oil under the car.

> I guess maybe I'll try and find a local mechanic who can work on Jaguars.
Actually: No. In your case you would be better of looking for a repair-shop, which specialized in car-air-conditioning.
And when you found one, hand him the TB (Technical Bulletin), which Bob (motorcarman) has sent you above as additional information.

Smile Replacing A/C Compressor

Thanks for clearing up the "leaking" diagnosis and I will look for an A/C repair shop. Also, I didn't know what to make of all the letters and numbers from motorman so I appreciate the clarification.

If you click onto the attached PDF from motorcarman, you will find that this automatically downloads a TB, which you then find in your download folder.
Motorcarman worked as Jaguar Mechanic and he has access to all kinds of TBs.
If you print that out, it might help the A/C-shop, where you bring your car....
It might be a good idea to let the shop look at your AC-system, before you leave your car there for having it fixed, so that they can order the required special parts as listed in the TB.
Which parts you need seems to depend on your VIN-number.

I had an issue years ago with the the compressor blowing warm air so I did the Jag update which fixed my warm air issue... Three years later I started hearing a knocking noise, although the compressor was still blowing cold air. I dropped the compressor and sure enough it was bad. A very small amount of silver thick oil came out, maybe a tablespoon. When I pulled the orifice on the firewall it was clogged with shavings. That is the reason I replaced the dryer, orifice, condenser and compressor.

So if your car is just blowing warm air but is quiet I would do what the PDF update suggests. If not it may be the compressor is bad. I would try that first.

I would do as Peter says and stay away from the Dealer. Find a small shop that does Jaguar work or an A/C shop.

@OneLovelyCar
If you look at my link posted above, you will see a substantial compressor failure. The "green" shown is the fluorescent dye (shows up under UV light) in the compressor. It never leaked beneath the car.

BTW, we sometimes take for granted our shorthand car speak, a TB is a "Technical Bulletin" issued by the manufacturer(s).

Motorcarman's first reply is a list of aftermarket compressors that work in the X-Type. i.e. "gpd 6511486" is part number 6511486 from GPD (Global Parts Distributors). Currently for sale at $205 on Amazon. The point being that a Jaguar branded air compressor is not required and is probably unnecessarily expensive for a replacement part.

I think Peter's advice above is spot on, find a reputable shop specializing in air conditioning. Or maybe two and then choose the one that seems more trustworthy? They should be able to fix you up quick, I bet not many people are complaining about insufficient A/C in Chicago this time of year.

We do not know for sure, if "OneLovelyCar" is from Chicago, as she wrote "Chicgo"...
Maybe Chicgo is a place somewhere, where the sun always shines and where all the cool CHICS GO...

Funny how my brain doesn't work sometimes. I had to look at that "Chicgo" for a minute even after you pointed it out before my brain stopped filling in the "a" where I expected it to be.

...where the sun always shines and where all the cool CHICS GO. 😂 Good one. Yes, that was a typo. And no, there is not a whole lot of need for A/C when the temps here are single digits so there is no urgency to fix it. But you've given me a lot of good advice😊
