Mine is hosed. Pun intended. Ive searched the threads and cant find the answer I need. I have a Chevy 400 cid small block, so a XJ6 radiator wont cut it. My radiator guy says he can re-core for about $500-$600. I figure that's my best bet. If anyone has a suggestion, it would be greatly appreciated.

Also, are all series I, II and III's the same? That might make my search easier.

Thanks.

 

OK, brain kind of clear, as its before midday.

'73 XJ would have been carby engine, I think. The plumbing on them was different, but I seem to remember the radiator part was the same as the EFI engines??????. Although I am unsure of the banjo on the RH side on the carby unit.

The S1,2,3 6 cyl radiators did change as teh models developed, so forget that.

The V12 radiators also changed. The S1, and S2 were a 4 row core, and monster tanks, and are referred to as the PreHE radiators. The HE (about '82 onward) got a 3 row, and smaller tanks. This was pouted as radiator technology was now more advanced, blah, blah, blah, but the HE units were definately more efficient. Also bear in mind that the HE also saw Plastic fans replacing the Steel fans, and the plastic fans do draw more air.

I would be recoring your unit, at least you then know EXACTLY what you got.

 

I run a Summit Racing alu radiator. The part number is....
SUM-381331. Its fits perfectly will with some universal radiator mounts and I use Camaro hoses. BTW I have a SBC 408 and I have no over heating issue what so ever.

 

Have two S1 Jags with Chev engines.... LT1/700R and 383/200R.

Both have gone years with stock Camaro/Firebird replacement aluminum radiators, stock Chev dual fans on the LT1 and dual Ford Probe fans on 383 SBC. Have seen 122F in So Cal stop and go traffic with the AC on and no problems.

Be sure to seal around the top and edges so all the air flow enters the radiator. It drops right into the stock Jag location with the use of (4) GM rubber radiator isolators.... replacement cost <$150.00 USD with Lifetime warranties.

 

That sounds steep for a recore on a V12 radiator. I was quoted $200.00 a few years ago, based on me pulling the radiator and bringing it into the shop.

 

Yeah, the day of a 200 recore is long gone. When I did my hot rod, it cost 350 for a decent recore. Well done and the car ran great and in spite of flat head V8's propensity to overheat it did just fine.

My lump has a four row brass radiator and cools just fine with an electric water pump and dual electric PCM controlled fans.

On balance, Rogers suggestion is the best. The plastic and alloy units defy fixing, but economicaly replaced

Big arguments as to alloy vs brass.


Do not run it hot.. Been there, not good.

Any particular year Camaro/Firebird?

 

"The model originally designed for 87-90 5.7 L Camaro IROC/Z28/TransAm is a perfect fit for either the XJ6 or XJS (It is Modine #951)." Purchase (4) rubber
isolators from a GM dealer to put on the top and bottom and it will bolt in...
cut out a hole for the radiator cap in the top support.

Read about the difference in the reverse flow radiators used for the LT1 engines...

Quoted from Jaguar Specialties website... Check out the fine Tips Section.

 

My radiator guy said it would be $500 to recore the 5-core original. I told him about what I found here, especially Roger's story about 122 degree heat. He said it sounded like I should go with one of the radiators recommended here. Honest guy.
Thanks to all for the advice. I placed an order with Summit an hour ago.

 

Thanks everybody, for your help. I just got back from a test drive. Cooling well.

 

I keep taking "test drives". One of them ended at a nearby lake.
