Hello,

I am looking for the low pressure port on my Jaguar S Type R 2004 Supercharged V8, I know where it is, main problem is that it's damaged and I can no longer attach anything to it thanks to the great mechanics of my land and I got multiple options, like weld it and charge the freon through the high pressure port, find at the scrapeyard the low pressure and weld it there or change the entire pipe, and I decided the most sensible and resonable choice is to buy the entire pipe. I tried finding it on EPC but, it doesn't work and it doesn't show me any pictures, tried looking for it on parts.jaguar but nothing, the only lead I found was on justanswer but sadly no number part.

Can anyone give me a hand in finding the part number?

Jaguar S Type R 2004 4.2 V8 Supercharged V8
VIN:SAJAA05M49FR14714


Thank you kindly.

I know that this procedure will cost me a kidney and a half, but it is that it is. I will await for other opinions as well.

Is item #1 the hose you need? If so, it looks like XR854251.



However, I'm not sure that matches what you have. I'm not seeing a service port located in a tee in the middle of the line. The illustration isn't super clear, but it appears to have the service port as part of the manifold that bolts to the compressor (where #13 O-rings are illustrated, secured by bolt #16). I ran a quick search for XR854251 and found some good pictures on eBay. Same thing, though, it does not appear to have the service port in the middle of the line and details at the compressor manifold were not clear. If this part number has the service port in a different location, I have no way of knowing if it would work for you.

Sorry I don't have a more definitive answer for you, but maybe it's a good place to start.

 

Looks like all the 4.2 liter S-Types supersede to XR854251?(from XR833220 and XR852780)

 

You could try searching for those two earlier part numbers, too. You might get lucky and find they are still compatible for your car. No idea what the differences might be.

 

How is the low pressure hose damaged? I didn’t see any actual damage but the valve core looks a little jacked up and if that’s what the problem i am not too sure you should really blame your mechanic for that. I have a 2006 STR. it’s been well maintained and when I went to service the AC I had a difficult time connecting to the low pressure port. I managed to connect to the low pressure port but my low pressure gauge didn’t move off zero. It also wouldn’t let me add any refrigerant to the low pressure port. I had pressure showing at the high-pressure port so I was confused and disconnected the gauge set and tried to reconnect it and that’s when I noticed that the low pressure port valve core was frozen solid in the closed position. And when I tried to connect to it my gauge set could not push the valve core in. it just bent it all to hell.

I tried ordering a new valve core online and quickly found that Jaguar uses a somewhat unique style that’s not readily available everywhere and that most of the valve cores sold were of a different styled it wouldn’t work.

so I decided to take a valve core out of my parts car that I have. It’s also a 2006S type but is the 4.2 L naturally aspirated. Well when I went to remove the valve cord from the parts car I found that it too was frozen in the close position and would not allow the plunger to be pushed in at all.

So I guess what I’m saying is if your problem is the valve core was frozen you cannot blame your mechanic for that as it appears to be a common fault. Probably because that valve core is up underneath the wheel well and gets a lot of moisture on it at least that’s my assumption. So if that is your problem you might want to look online see if you could just replace the valve core as I did. Good luck

 

This may not be as crazy as you think. Years ago, I had an Audi that didn't even have a low pressure port. All servicing was done via the high pressure side. Apparently this was common with German cars. The charging procedure was a little different, as the engine had to be off, but it worked just fine.

Rather than welding, I wonder if you could plug the port with epoxy and then fit a cap to help retain it. Even if it failed eventually, you'd be no worse off than you are now.

 

I ran into a similar issue when the high side service port was leaking on my '02 V6. It was an oddball size. A standard valve core tool didn't fit, either.

I removed the valve and measured the diameter and thread pitch. Can't remember where, but eventually I did find one online. Might have been an assortment kit on eBay.

 

Went to a specialized mechanic on Climate units, he told me I need a new Low Pressure Pipe line since this port is damaged, he tried removing the old port no chance, it was bent as well. I guess I will have to buy a new Low Pressure Refrigerant Line. But thing is which one is the right type for the S Type R.

Found this one it looks similar to the one I need, I think.

 

The right part number for the 4.2 NA and R should be from what I inspected and saw from my photos


XR842545

Will wait to see if there is any member that can correct me on the following statement that I have made.

 

@ turkay: Aarcude asked already above, but I don't think you answered: WHAT EXACTLY is damaged? Is it just the valve core?
If I google for "A/C valve core Jaguar" I get hits... would those valves not solve your problem?

 

Tried, he couldn't remove it. I asked him if he can he said maybe, he tried like 4 times, nothing and then he told me I need a new line.

 

Well, I am a DIY-er. I don't care much, if anyone says, it is not possible.
I suggest you don't take the word of "him", and try yourself:

This is what you find, if you search for a "valve core remover", e.g. on ebay. It costs less than AU$2.

There are other valve core removers, e.g. those, which double up as actual valve cap. Those can work for valve cores of tyre valves, if they are NOT stuck. But if a valve is stuck and you use a toy trying to remove it, you don't get far - and I just do not know, how "he" attempted to remove it...

So I suggest you order a cheap proper valve core remover and spray penetration spray in there and let the spray sit in there for a couple of minutes before attempting to remove the valve-core.

 

Is the damaged valve leaking?

If the core needs to be replaced but a valve core tool can't grip it, try this. Take a valve core tool and modify the shoulders at the end. Right now, they are flat. File them at an angle, like a reverse hole saw. Tap these new teeth into the damaged core and hopefully they will grab as you try to unthread it.

 

I will give it a go myself, maybe I can get the valve cover out.



This is the Core Valve removal he has.

 

Get one like peter shows and use a pair of good pliers to hold the fitting because the line will try to twist. I have tried the other remover and cannot get good power on it
