I've got the radiator out of the XJS and thinking about a swap since originals go for $600-700 dollars and aluminums are supposed to cool better. Didn't see any threads where its been done but doesn't look to awful hard if measurements match. So far it sounds like aluminum dual core is good cooling design. So far i've found three that sort of match up:
1971 Mustang
1990 Camaro
1963 Skylark (except output hose on opposite side)

Any thoughts/concerns/warnings???

Thanks

Here was the other site that has several performance things for the Jag V12. Aluminum radiators, cooling fans ans even Intake upgrades. If the link dosen't stay, it is www.v12performance.com I was looking for this site the other day when I posted, but couldn't find it.

Don - I just used a regular radiator shop in Fort Worth which happened to be convenient. Re-coring is not rocket science, as long as the basic 'reservoir' is sound. Just check around in SA and visit a few. I paid about $300 a few years ago. You might like to join the SA Jag Club where you can get lots of good advice if you're not already a member. Also, check with Victor's Service a great Jag specialist and see what ideas they have. Good luck

This is for Rick W regarding 1995 XJS

Rick from your post above you claim that you have a rare 1995 production car. There were only 78 1995 XJS V12 6.0 2+2 made in the calendar year 1995. I think only 27 were shipped to USA. I have attached the production numbers to this post. Please look at your door sticker VIN tag and identify the month/year of manufacture. The 1995 model year includes cars built in 1994 (July-Dec 1994 Ford Model changeover). There were a total of 1030 XJS v12 6.0 2+2 build in 1994, I do not know how many were marketed as 1995 model years, nor do I know the quantity shipped to the USA. My 1995 was built in Oct/94 and purchased in May 1995 (took ownership). It is just like yours Black, 2+2, same rims (my chrome wore off so I put on some cheap aftermarket rims until I get my re-chromed). A work of caution, your car may have the 110volt plug-in block heater, Nobody can find the two block heater cooling hoses, so I was forced to remove the block heater and replace it with the single standard Jaguar lower hose. In June, I replaced all of the coolant hoses, The upper left radiator hose is the most expensive around $120.00 if you can find one, anyhow, you can contact me directly at: merklesatcomcast.net.

D.A. I had my E-Type radiator re-cored with a modern high efficiency core. Less than half the price of a new one and it works like a charm. Probably will do the same to the XJS.

I just had mine refurbished in March. I have a '92 XJS 5.3 V12. I don't know where you are, but Sims Radiator in Doraville, GA only charged $89. They said it wasn't really that bad inside. No recore needed, just rodding out. You may go that route and save a bundle. Fortunately the previous owners ignored the instructions in the manual to add the Barr's stop leak. I wanted to keep the Copper/Brass original. I also changed both thermostats and all the hoses. Now it cools like it should. It was a process, but I do not regret doing it myself. It was a learning experience that gave me the confidence to change the plugs. As long as the computer stuff is all good, these cars are not as intimidating as they look when you raise the hood. I've included a photo after I was done, just before the hood went back on.
You would have to customize the radiators you mentioned, because I believe those only have one upper and one lower hose. You're gonna need two uppers. I can't think of anything else with two upper hoses. There are electric fans out there too, I considered those, but didn't need them in the end. Those are at v12s.com.
Good luck and keep us posted with the results.

If you have the original radiator, why don't you just have the original radiator re-cored? I just had my 95 xjs v12 re-cored in June. The total cost was $350.00. The shop used the same cooling fin size.
