Hello, new to the forum and a Jaguar XJS with a few issues.....

Firstly we have a leaking oil cooler or pipes, still searching for the precise point but keen to explore the removal of the cooler and kit needed to do this ?

Secondly electrical issues, drivers seats all functions, mirrors with both sides, currently cleaning all earthing points and connections

Thirdly, handbrake works but has lost its ratchet

Any advice on the above would grateful, parts to buy any hidden earth points that you can't see

Kind Regards

 

Jag06530,

You haven't said what type of XJS you've got, but I'm guessing it's a 1995 4.0 Convertible? (If it's a 1995 car, it's not a Cabriolet; that's a very different XJ-S that was made in the 80s.)

If it's a 4.0, then the oil leak is very likely from the connection of the pipes to the cooler. And as you may know, trying to detach the pipes from the cooler is unlikely to be successful. The good news is that, unless you're in an extremely hot area, you probbaly don't need a cooler so could just fit the bypass kit to the oil filter housing plate.

As regards the handbrake, not sure I understand the "lost its ratchet" comment? You do know that the handbrake is designed to drop down when in use to avoid your leg catching it when exiting and entering the car?

Cheers

Paul

 

Hi, thanks for the reply and yes 4.0 Cabriolet

Bypass kit do you have link to fitting or a company ? I'm in France so not silly hot and also lack of parts shops here

Britishparts I've seen mentioned but would welcome any pointers toward other shops online

Noted for the handbrake thanks

 

Hi Jag06530

Same problem on my V12 with a Leaking Oil Cooler and having had this happen before with my other V12 the first time I replaced it with New Oil Pipes and a New Oil Cooler that Cost me 'Megabucks' to do and Yes! Paul (ptjs) is correct! removing the old Oil Pipes is an almost impossible job (dissimilar metals and all that)

So when the Oil Cooler broke on my other V12 I just cut the Pipes with the 'Bread Knife' (as you do!) at the Oil Cooler end and then undid the Fittings from the Car as they are Similar Metals and undo easily

Then off to my Hydraulic Shop, where I gave him a 'Drink' to make me a Pipe (Think it was £20) Put it on in under an hour and then I was 'good to go' maybe not advisable in you live in a Hot Country but in the UK we unfortunately do not have that problem

Removing the Oil Cooler and Replacing it with a Pipe! (£20)

 

Thanks, so just to be clear you cut the pipes at the cooler as this are impossible to unscrew and then took the poiler cooler and pipers to a hydraulics shop top replace the pipes and reattached the whole system ?


Has anybody cut the pipes leaving the oiler coller in situ and attache the bypass kit ?

Any links to buy this kit please ?

Electrics

Lost indicators, mirrors and passenger seat movement, all fuses checked any pointers please

 

Convertible, not a Cabriolet!

The bypass kit was fitted on the x300 saloons, hence the belief that the XJS doesn't really need a cooler.

No-one else makes the parts for the bypass kit, only Jaguar made them. The main bypass block plate with the U-pipe isn't available. However the little connector valve is, and you could source suitable O-ring. If you search all teh threads here for "oil cooler bypass", I think someone measured the exact size? You might have to use eBay to find the connector block or a whole unit from a parts car. See Jaguar's parts website here for the x300 saloon oil filter & bypass parts:

Genuine Oil Filter-3.2/4.0 Litre (less 6.0 Litre) For Jaguar Xj 1995 - 1997 (from 720125 To 812255) (x300) Classic | Jaguar Land Rover Classic Parts

If you fit the bypass, I would also remove the oil cooler as you'll improve your water rad cooling with it gone.

Thanks Paul, I've add some photos from todays work

You can see the we have metal connecting pipes to the cooler itself and then flexi's to the oil filter plate





I've attached a link to the following part

I think what Orangeblossom meant, in post 4 above, is that he cut the two flexible lines exiting the oil filter casting (ie the lines to and from the oil cooler) and joined them together, thus short circuiting the oil cooler circuit in and out of the oil filter casting.
In detail, he unscrewed the two cut pipes exiting the casting, the took the metal ends with their cut pipes to a hydraulic shop and asked them to make a single pipe with the metal pieces attached one to each end, then screwed this asembly back into the casting. Job done.
Then you can remove the redundant lines and cooler matrix and sling it.

 

That's interesting that Berkshire Jag seemed to have manufactured the bypass pipe (or else previously bought up some of the original Jaguar parts and put them together to make a kit?).

If they still have that in stock, I would buy it now and fit it. (I have a set of the original Jaguar parts for the day that I might need them!)
