Radiator Differences
Hi Everyone,
Been looking at various options for radiator replacement or refurbishment, and I noticed that some list replacements as fitting "1976-1996" whereas others say "up to '87".
Gaudin Jaguar's online parts catalog lists the same part number for '85, '87 and '90.
Is there a difference?

PreHE, up to about 1982 was a 4 row core.
HE, 5.3 was a 3 row core. So 1982? to late 1991.
Some changes to the trans cooler adaption occured is 1986/87. They went from push on with clamps, to threaded fittings.
Physical size is the same, BUT, that extra row on the PreHE is on the engine side of the radiator. The end tanks of the early radiator are larger to accomodate the thicker core.
I ran a PreHE radiator in my HE for a week or 2 whilst waiting for a new core for the HE radiator. The fit was tight, but doable.
MAYBE, the radiator suppliers are now only using one radiator for the 5.3, which makes perfect sense.

I had my 1989 radiator re-cored a couple of years ago and the old girl stays cool even in 40°C stop-start traffic.
The guy who did mine advised the newer 3 core was a better solution as long as the flow rate is good. Cooling is all about flow rate and a thicker core can hinder heat exchange.
I would have your current rad re-cored, easiest option and will be plenty of cooling, just make sure your fan clutch is good as well. To do this warm the engine and turn it off, the fan should only turn a few times.

The fittings change is simple. Cut the flare nuts OFF the existing trans pipes, usually just above the alternator, partially "flare" the ends a very small amount.
2 short lengths of trans cooler hose (10mm) and 4 clamps, all done.

I was originally planning on just getting a re-core done on the OEM radiator.
Funny thing is, even though I live in a major metropolitan area, a lot of specialty shops have been zoned out of existence. The radiator shop I used to go to is closed, and the nearest one now has prices quite high due to a lack of competition. So far, a new aluminum radiator off the internet is much cheaper than any quotes I've gotten so far.
