Default Radiator Woes

I'm resurrecting my 77 XJ6-C, after sitting for 15 years.In the days when I drove the car it ran hot. So I did many cooling things including installing a 4 coreradiator. I took that radiator into aradiator shop and learned it now leaks from the core and can't be repaired; butit can be re-cored, with 4 cores, for just $550. Whoa! Seemedkind of pricy to me.

Is this a fair price? Do you all any experience in this area? I live in Phoenix and with the air on in the summer it's a big challengeto keep it cool. Half measures won't do.

Thank
geneo

One alternative, possibly.....


Some Series III owners have used an aluminum radiator from a later model Mustang with great results. Almost perfect fit and great cooling, an available for $200 or so. If it'll fit a Series III and pretty sure it'll fit a Series II.

I'll try to find the specifics later today...if nobody chimes in sooner

Cheers

Geneo:


Was the original you installed a new or recored unit? If so, I's check with the source. Warranty?


And, I suspect you mean, four row core, that is four rows of tubes in the core.


And, yeah, I see the shop's points.


Sometimes leaks in the core can be reached and soldered. Elegant at times, and not so much at times!!! The rub is the condition of the core,and that more holes are "on the way". They don't want to be blamed for that.


Unless you are a purist, an alloy radiator is a great possibility. Units designed for Camaro's or Mustangs, I dimly recall some using them.


In LUMP land, many are found.....


The discussion of brass vs alloy in radiators is alive and well.


And, yes, $550.00 is "reasonable" in today's world.


Cores are not cores. Look into that In your world, you need the best you can get. I recall my 118 F days there.....

Ooops, Doug popped in while I was typing. More info to help deciding.


My lump lives well with a quality four row brass radiator and twin e fans.

$550 sounds about right, as it is a copper core, and copper is still rather costly albeit lower than recent times.

Doug's suggestion sounds good

Doug, I too like your suggestion. hope you can find specifics. Alloy radiators dissipate heat really well; 1st thing when you're building a race car!

Geneo:


Or is it the lighter weight of the alloy radiator that appeals to racers ?
Our salons are heavy and weight seems not an issue.


But, the cooling capacity of an alloy core vs a brass core lingers on, at least in some minds.


and, the alloy/plastic units re "throw aways", while brass units can often be repaired.


Not that I have any bias as to an alloy unit. They work and the price is surely enticing.


The racer catalogs offer genric units that are downright pretty, but, a tad pricey.

2000 Mustang GT with the 4.6 V8 engine

Note that I don't have personal experience with this radiator but the topic was hot 6-7 years ago on the J-L forums

that price is highway robbery. Contact David at Everyday XJ to see what he has. If no cigar, and you can afford Aluminio, contact Rock Browning at Porsche, Ferrari, Mercedes A/C Kits | RetroAir Inc. and see what he has.

Thanks so much for the help. The Mustang radiators mentioned above are available for $200-$300 in aluminum, but are all 3 row(carl) while mine is a 4 row.


Question/opinions: Does a 3row aluminum cool as well as a 4row brass/stock?? This ought to be good!

Why not use a radiator from an early GM 350 engine as found in the Camaro / Firebird cars,..often used when converting to GM V8 power. Drops right in.

Check with Andrew at Jaguar Specialties he posts here often about 100 dollars - no modifications.

that is the best solution so far. Who knows if the oem radiator is a GM part.

Geneo:


Many claim that added rows are a victim of diminishing returns.


And, some will say that three alloy rows match or beat folur brass ones.


Of course, others differ.


Think, heat exchange. How many BTU's do the engines develop. HP production is a clue. Then how many F' are excess to be swapped in to the ambient. Engine temp vs ambient.


Or merely, engine to engine. If it will cool a 360 chev, it will cool a 4.2 Jaguar. Or if it will cool a 4.6 Mustang, it will cool a 4.2 jaguar.


And, Jaguar cooling systems are maginal at best. Gotta be in top condition, especialy in hot climes like yours.


Camaro's and Mustangs not know for heat issues, jaguars ????


Any of the aformentioned will work,


Carl
