I've been trying to source a used (mechanically sound) OEM (original) radiator, for refubishment/spare.

However I can only find one on ebay at $169 plus S&H.....OK price but it states "screw cooler fittings" in the description.....what is in the car at the moment are obviously "push on" hose spigots, secured by traditional worm drive clamp bands.

A check at Heritage and SNG comes up with "screw fit cooler pipe" in the description.

OK, I've got to be "missing" something here....but what?

On a slightly different note......it looks like, more than a few, folks have installed the aluminum rads.....so where are all the old take off originals? Anyone got one/a few just gathering dust?.........also looks to me that the 5.3 and 6.0 rads are the same.

Thanks,

I would hazard a guess that the reference to screw cooler fittings is referring to the trans cooler connections on the side tank not the water hose connection.

 

Duh!!!.......you nailed it......I knew there was a trans cooler....still odd though,to specify "screw fit cooler pipe" rather than "screw fit transmission cooler pipe"....guess they might have made the rads in the early days with push fit/clamp fittings, for the trans cooler?

Whew! Glad that's cleared up....wanted to make sure I was buying the right thing.

Many thanks for your response.

You're right, earlier conections were push on hose clamp set up.

 

Hi

These Rads are from a couple of 1990 5.3 V12 XJS's

One of these Rads has a tightly packed Core, while the other one is more open to air passing through it.

Which one to choose is enough to prompt a discussion on its own.

But out of the two my own personal choice, would be for the more open Core, though sometimes you just have to run with the one you have got.

As you have already found out, the screw on connections are for the Transmission Cooler, which will need topping up when you fit a New Rad.

Although your Radiator may have developed a leak, its very unlikely to be the same, with the Transmission Cooler part that's on the side and that is one of the reasons why a Re-Core will be cheaper than a Brand New one.

Having said that, it can be quite expensive regardless of which way you decide to go, with a New Rad in the region of £500, with a Re-Core in the region of £360.

Although there are a number of Brand New Alloy Rads on ebay that have been made in China but don't know if they are any good or not for around £165.

These have the Push on Connections, for the Tranny Cooler and although you could cut the Screw on connectors off the original pipes and convert them to push on, I wouldn't do that.

As it would cause problems, if you wanted to go back to the Screw on type later on, if the Alloy Rad didn't work out for you.

It would be very simple and also much better, to get a Hydraulic Shop to make you a couple of Pipes, that Screw into your Screw on Pipes, without any connectors on the other end.

So that you can push them on and then secure them with Clips, while the extra length of these 'Adaptor' Pipes would give you more room to work.

Thanks for the photos and the info. Looks like both types were in use/available as "recently" as 1990.
