Hey so a few months ago I had 3 different radiators for the V12 XJ-S, and finally found this info. BeCool Aluminum 62082 Single Pass, the CatCooler Aluminum Dual Pass (V12Perfomance.com /Wizards Radiators), and the OEM Copper Dual Pass Radiator. All of the weights are the dry weight.

BeCool: 15lbs, 2in core, 40 rows, 27.5" x 16.75" with draincock
CatCooler: 19 lbs 4 oz, 2" core, 37 rows, 27.5" x 16.5" with draincock. Top 4" of radiator is for the left bank bottom 12.5" for both.
OEM Copper: 25lbs 15 oz, 1.75" core, 43 rows, 27" x 16.75" no draincock system on my '90 version. This also was completely clean with zero stop leak used.

My intention for this post is not to start a Dual Pass vs Single Pass War (as many other forum posts have already hashed out). This is just for providing the facts for anyone looking at purchasing a new radiator for their V12 XJ-S.

I am going to use the CatCooler radiator (still piecing the car back together). I wanted the extra cooling capacity plus the original OEM routing. I also got it for a steal, used from a Jag-Lovers forum member who totaled his car right after a long restoration. The Quality also seems to be a step above the OEM and the BeCool.


The CatCooler uses thicker aluminum vs the BeCool and definetly feels more robust. The inlet and outlet flanges on the CatCooler are stronger and less likely to crush vs the BeCool and OEM.

Good info there.

I have always stuck with OEM, but I suppose things have changed in the recent years. Its been a while with the V12's for me.

That 6lb lighter will have that beast fairly flying, haha.

 

I put in a Becool radiator because my original unit was leaking where the core met the tanks on both sides. I don't have any beef with the becools quality or function, it's a nice radiator, but if I were to do it again my choices would be: 1) recore my original, 2a) new oem, 2b)new oem style 3)becool. It was quite a pain to plumb the two engine outlets into the one radiator outlet, and even more of a pain to adapt the trans cooler hose fittings. Also though the pins on the bottom fit right the "body" was not exactly the same dimensions, so mounting the top rail and fan shroud took some adjustment. I thought doing it the way I did would be quicker than recoring, boy was I way way off! Price is probably somewhat similar for any option, recoring maybe a little cheaper.

That said, now that it's done, I've had no problems at all with it.

I have PO BOX in the USA, UK and Deutchland.
I do not care where to buy.

 

I purchased the CatCooler that WiardCooling makes... It is Still in the box as I am just finishing up scrapping rust off the fan shrouds and have repainted them. I had to remanufacture all the grommets that hold the electric fan in it is all going to look good I am sure it is going to work great Will upload pictures later...

 

I haven't looked into it enough to give you specifics, but given the cost of those things ($600+) I have considered converting from the jaguar design. The other brands, chevy, ford, mopar, all have similar layouts, and one of them would fit if you joined the stats together.
I think it would be worth it, just pipe the left hand stat over to join the right one. Re-route the trans cooler line, and you have a $200 radiator that performs like the $600 jaguar aftermarket radiators, than can then be replaced for $200 if it is ever needed.

This would make the ROI on the Jaguar designed out at probably 50-60 years? Other than originality, whats the point? The aluminum is already unoriginal. I am all for that, but I drive my car daily, and I'm glad to fix something that is overall better for the health of the car if it sacrifices one little thing (like putting in a new fan where the old one was when it goes out).
Also, that piping could be un-done pretty easily.

 

I hesitated for a long time. And yet I bought.

Cooling is much better. Even the air conditioning is cooler.

Yes, the installation is not just plug and play.
The banjo bolt threading. No copper washers, aluminum only .
The fixing pins are not in the right places.
Modified transmission cooler hoses.
If you understand what is it. I'll recommend that radiator.

The alloy has a threaded hole for a temperature switch. It is really necessary.

I sprayed it in the black so that it does not stand out.
