I bought the Jag about a year ago from a private party. I developed an antifreeze leak. I put the car on jack stands in order to look under it. As you slide under the car from dead center front, when you get just past the radiator there is a large metal, rubber reinforced,back to a metal crimp fitting, then to a pipe that appears to 90 and go to the front bottom right side of the radiator. On the left side it has a large coupler. I can see how to undo that, but can't see where it goes into the radiator. It appears to have fresh oil on it. The oil was just changed before the overheating issue started. I had it towed home to work on, but then was hit by a big truck two days later with my pickup. I am trying to find out what the name of that line is. It seems I'm not to up on my British English. I'm trying to find out if I can order the whole thing, or if I need to take it off and take it to a custom shop that does that type of work. Would be very happy if someone cold tell me what that line is called. Thanks for any help that I can get.

 

They are engine oil cooler pipes and go forward to the oil cooler mounted in front of the radiator. They do not need to be touched to remove the radiator.

 

Might I suggest you get a PDF copy of the Jaguar Spare Parts Catalogue.

I got mine from JagDocs. It has really good diagrams. Also look up SNG Barratt they have good images as well. Then you can talk part numbers

 

I do not want to take out the radiator, I do have a jag manual, but don't seem to speak the queen's English. i thought it was an oil cooler hose. can it be removed, and a new one ordered, or do i need to remove it and have a shop fabricate one? thanks.

 

I'm a bit confused, but then I'm old..... lol
You stated you have an antifreeze leak, then it appears you want to fix an oil leak ?? As suggested before, at least download a parts book you can refer to so we are all speaking the same language..... So go to SNG Barratt, open an account (free) and down load what you want and relate your questions to a specific part or page.

SNG Barratt - The Ultimate Jaguar Parts Specialist

If you have a cooling system leak, have you been under the car when it is running to see where the leak is coming from ???? Under pressure when engine is on, you should be able to quickly identify where that leak is......

As for an engine oil leak, just because some oil is on a hose does not necessarily relate to where that leak might be originating from..... If you regularly park somewhere, the oil drips "might" help to locate that point, but again, not necessarily so. Also, how much oil are you loosing per 50 miles ?? Once again, you might only have some oil drips resulting from replacing the oil filter which should be filled prior to placing in position and that might leak a bit if tilted too much !!!

You are now the owner of an "antique" and "rare" Jaguar XJS. Be prepared to pour over manuals, pictures and this site for information.... BTW, if you have an unlimited money supply, go to a dealer.... Otherwise, become familiar with your "Cat"... Do your own oil changes, etc.... I am 73 and this is my first Jag and I do all my own work.

Good luck

 

Yes she developed an antifreeze leak, and I had it towed home. Two days after that I was hit by a big truck while driving my Ford Ranger. I was injured pretty bad, so I wasn't able to try to track down the leak. That was in July. This is the first time I have felt well enough to put her up on jack stands. I have not been under the car with it running yet to track down the antifreeze leak. I figured that while it was on stands I would fix the other things that I know are wrong with the car. I found that I had a bad belt, so I came inside and put in my manual to look up the belts. My husband found another belt that I had missed, he also found a bad belt that I missed. I went under the car to check the drive belt, and when I slid under I found the bad oil cooler return. I have downloaded that site and a parts manual from them. I figured while shes off the ground I will fix the other stuff that I find. I'm putting on new shocks all the way around, and putting new brake pads on the front as well as fixing the two belts. When I get all that done, I will track down the antifreeze leak. Some parts that site doesn't even have for my car, so I need to look elsewhere for them. Know anyone who has some good hood struts for my car? The left one needs to be the locking kind. Looking for the V12 emblem that goes on the front grille as well. Thanks for the advise. I've learned a lot in the last few days. I am really enjoying this forum.I do most of my own work. I have a manual that would used in a Jaguar repair shop. It has parts, repair, and service manuals on one disc.

 

The first place I look for parts is Rock Auto;
RockAuto Parts Catalog
Its a good place for things like the hood struts. Much cheaper than almost anywhere else. I'm not sure about a locking strut. That might be more difficult to find.

A good source for used parts is David over at EveryDayXJ; Everyday XJ
His prices are very reasonable. If you don't see what you need on his site just send him an email. He will get back to you quickly and let you know if he has the part.

And of course we also have the Parts Forum here at Jaguar Forums. You can post a want-ad for things like the grill emblem. Those emblems are no longer available new so the best you can do is to find a good used one.

Good luck!

You don't need locking hood struts. I bought cheap URO brand struts when I got it, and they have been working for 5 years.

The oil cooler line may have several names, you just have to try different combinations or filter through sections on websites. You CAN have to replaced at a local hydraulics shop though, and it may be cheaper that way.

If you just google "XJS oil line" for example, multiple examples come up, just look through them until you find one that matches the part you are looking for. You could try things like oil hose, oil cooler line, oil cooler hose or pipe, but making as simple as possible is usually the most helpful.

As an example, I replaced my high pressure power steering hose for 60 dollar locally instead of buying the part for $130~ they also made it modular so I could replace pieces of it in the future, rather than the whole thing.


If you haven't had it running, look for evidence of buildup from a coolant leak to track it down. By this time the water pump weep hole may be leaking, indicating a failed water pump, or you could have a bad hose thats not sealing anymore, leaving streaks running down nearby areas.


From grill emblem will probably be off a parts car or ebay.

 

Love the 1989 and 1990 Jags! Both very beautiful. Thanks for all the advise. Been looking on E-Bay for the V12 emblem. I'm going to take the oil cooler hose off and take it to a local hydraulic shop to have it repaired. I got a price on the part for 159.00, and I'm sure I can get it done here a lot cheaper than that. I want to thank everyone for the advise it has made me look harder to find the information I need, and studying my manual to figure out how to fix things. Again, Thanks all.

Are you a gal or a guy? Not that it matters, but if a gal, it's nice to know that a female view is involved.


David is an all around good guy. As well as tons of good used parts, he does have a lot of NOs as well.


I like the idea of using the local facilities for hydraulic hoses. Farm oriented parts places are inclined to have that ability.


My son and his SOL have a place in CA's Sierra Nevada foothills. He acquired an ancient Case tractor. A hydraulic ram is a part. Leaked badly. Local place fixed it with new hoses and original fittings. Just the right stuff to crimp them. Most customers now "gentlemen" farmers!!!

Unless you are extremely lucky, removing the hose from an Oil Cooler is an almost impossible job, because the Oil Cooler is made of Aluminium and the Connection on the hose is made of Steel.

Resulting in these disimilar metals welding themselves together and in doing so are almost impossible to remove.

So before you go and splash 'big bucks' on a new hydraulic pipe, I would make sure you can get the old one off first, which in the very unlikely event you could do so, would almost qualify as being a 'Miracle!'

If you can't get the Pipe undone with a spanner (which is very unlikely) you could try 'Carefully' cutting a split down the ferule using a 'dremmel'

But if that doesn't work, you may have to replace the whole lot, with a New Oil Cooler together with New Pipes.

None of this is going to be Cheap but having gone through this myself, I would definately go for getting Pipes made, at a Hydraulic Hose Shop as they will be far cheaper and every bit as good.

In my own case I decided, to completely do away with all the metal bends and routed the Custom length Pipes I had made around the Engine Compartment.

Keeping them away from heat and avoiding any sharp bends.

Are you absolutely sure that its the 'Big dia' Oil Cooler pipes, that go to the main engine and not the 'Smaller dia' Oil Cooler pipes that go in the Radiator to Cool the Transmission Fluid.

Best to report back 'If/When' you get the Pipe off, then we can go from there.

Have something handy to catch any spillage of Oil.

Also you need to first decide if you are up for doing this job or would rather take it to a 'Shop' because once you Start, there is no going back!

 

In the very unlikely event that you can get the Hose off, as the Connection on the Oil Pipe, usually welds itself to the Oil Cooler.

Don't get it repaired, replace it with a new one.

Any Hydraulic Hose Shop, will make these up at a fraction of the Price and are every bit as good as OEM.

 

In the event you decide to replace the 'Brake Pads' make sure you undo the 'Bleed Screws first'

As if any fluid is forced back the wrong way up the Brake Pipes, you can literally end up 'Wrecking the System'

Which could cost a fortune, both in time and money to sort out.

 

I am a bit confused. If it is antifreeze that is leaking from some place, it isn't the oil cooler.


There is no antifreeze in the oil cooler. Although, it is a radiator of sorts, the system is filled with oil. Lots of it!!! The robust engine oil pump moves oil through it and returns it. Hot engine oil to "cooler" and back to engine a lot cooler.


I suggest more looking and getting familiar with the systems at play.

Jagcad is correct

Before you can fix the problem, you really need to be sure what that problem is.

If She is leaking antifreeze then if its not the Radiator Hoses, it could be the Radiator Core, which is almost certainly going to mean that the Radiator will

have to come out, for a repair or most likely a Re-core.

The Radiator is Two Coolers in one, with the Honeycombe core to cool the Water going round the engine.

But on one side of the Radiator, there are also Two Small Hydraulic Pipes for Cooling down the Transmission Fluid.

They are nothing to do with the Engine and not to be Confused with the Engine Oil Cooler, which is fed by much Bigger diameter pipes.

Your problem could be anyone or all of those three.

You might have a leaking Radiator and or an Oil Cooler and possibly but unlikely a leak in one of the Hydraulic Transmission Fluid Pipes.

If you are not too mechanically minded or don't feel up for the 'Fight', none of these jobs are exactly a 'Walk in the Park'

And can also be very expensive and time consuming to fix.

So first be sure that you have identified the Problem and also remember once you Start there is no going back!

 

He was just saying it was originally parked for an anti-freeze leak, and when inspecting the car for the leak, discovered the oil cooler line was bad and wants to replace it.

 

That does not sound like good news and could be very expensive, even if the owner decides to fix it themselves.

 

Thank you all for the comments. I am very mechanically inclined, as my brothers started teaching me cars at around 11 years old. I used to fuss about it, but when I asked my oldest brother why, he said that way when you are grown sis, no one can take advantage of you. It is not the transmission lines, and yes I know that the radiator cools not only the antifreeze, but the tranny lines as well. It is the oil cooler line that is leaking. I will take it off and go to a hydraulic shop locally to have one made for the car. Even though I live in the south it has been too cold for me to go out and trace the antifreeze leak anyway. I pulled my battery out and put it on a maintainer until it warms back up enough for me to go out and work on the car. Since my shocks and brakes are already here, I will do that job first, get the oil cooler line fixed and put back on, then I will track down the antifreeze leak. I know it could be a line, the radiator, or the water pump. It is something I will track down. Thank you all for the comments.

 

I am a gal. Thanks for asking. I do actually know that a ram is a part. I grew up on a farm, and drove dump trucks for 15 years. The dumps had a lot of hydraulic parts. I also operated heavy equipment (trackhoes, backhoes, front end loaders, bobcats, and things like that). I guess that makes me not the average gal. As my brother told me once he said I am not a girlie girl. I told him that it was his fault for making me work on the family and my brother's cars from such a young age. He will tell you now that I know more about cars than he does. I usually have american muscle, but this was my dream car, so therefore my first British car. I will admit I am on a learning curve, but I am not that far off the curve. Thanks for the comments.

 

Yes, I know which part it is. I will take it to a local hydraulic shop to have it repaired. If I have any trouble removing the fitting from the oil cooler, well I guess that's the part where it's a good thing that I am married to a millwright maintenance mechanic, who knows metal and can fabricate and weld as well. Thank you for the advise.
