Sorry if this has been addressed before, but a quick search prior to this posting came up with nothing. Alloy cooing radiators have been around for a while now. Has anyone had experience as to whether

1/. they do indeed offer superior cooling

2/. They last as well, bearing in mind that while aluminium can't rust, it can corrode.

With thanks ..

As far as I was advised from the workshop that refurbished my original radiator the only real advantage an alu radiator has is that it’s lighter. They said copper should in theory be a better heat conductor and also stronger.

 

But I guess a well made alu one should still be absolutely fine.

Hi,

they do not cool as efficiently as the standard copper radiator.

With decent antifreeze/inhibitor they do not appear to corrode internally.

 

They have a history of very bad fitting. The Chinese and Dutch offerings have had a lot of criticism.

 

Their only advantage is light weight - for the racing boys - and bling value.

This has been discussed a lot in the past but the search function on the forum doesn't always work well. If you do a Google search on "TR forum aluminium radiator" you get this list:

My local radiator fettler said that Copper radiators are much more resilient to movement, whereas a copper rad will flex a little the same amount of movement could well crack an aluminium one.

I was going to fit an Ally rad mainly because there SHINEY and I think look very nice but after reading previous comments here decided to go for a copper cored one.

I am driving with an alloy radiator, about 6.000km. with my original still in my garage.

If I would recommend any radiator I would use these guys: https://wizardcooling.com/ anything else, get your original one overhauled!

 

If you have a cooling issue, the problem may not be your radiator.

I have a long-neck TR2-3B Wizard Cooling aluminium radiator here in my parts if anyone wants to make a good offer on it. It's the second one, in fact, after the first one had a top tank hose outlet that was completely in the wrong place.

Wizard told me that they subcontract out work and whomever they gave this job to didn't really know what they were making, I guess. They sent me another which fit but didn't seem to cool as well as original. As part of a number of things I did to work on an overheating issue a re-cored original copper/brass radiator went back in and I'm happier with that.

 

No more Al rads for me.

There is no good reason to utilise an aluminium / alloy radiator in a TR except for competition - as in weight reduction.

 

That is a simple principle, quite apart from the fact that many of the ally rads on offer are total cr*p.

 

How often does it need to be repeated ?

 

Cheers

I’ve got an alloy radiator and it’s fine.

Same hear.... I do smile at some of the comments.... if you don’t have a rad to exchange or rebuild then an outright alloy rad purchase can make great sense at the right price (and they do look rather nice ;) )

...so we have the following I do / I don't dispute

 

GB/OD oil type - GB40, EP, ATF or cats piss.

TRunnion - oil or grease

Tyre choice - practical or expensive

Headlight bubs - filament, LED, HID

Surrey top or Rag top

 

and now

Radiator material - to bling or not to bling :lol::lol::lol:

 

We certainly have cars that can take a great variety - something for everybody

..... and not to forget the EFI, PI, Stromberg, SU oder Weber thing on the TR6.

Also the cv-jointed rear has been discussed often in the past..........

 

But isn't it more a chance than a pain?

While Bentley boys only can discuss turtle wax or food elsewhere in a restaurant

we are located between strong oldtimer restoration and sports car modification.

I like that and most I like if I drive with modified things in my TR where others quote

that this is impoosible or still claim problems with the original.

 

I would not swap to other cars like the way I work on or go with my TRs.

I also have a modern Maserati that does all things better than the TRs

(except acceleration of the V8) but it does not give that wonderfull feeling

you get when the TRs survived a holiday in Italy and got back home on own wheels.

Must be similar to Amundsen when he reached the pole........

 

Mainly that feeling happens after you did a lot by own hand on the TR

and also "improved" a lot that needs to be confirmed through

the time and miles on use.......

Thank you all for your input. Were I a judicious chairperson I would probably conclude that an alloy rad from a reputable source is ok, but that the original - in good condition - is just as good if not better. Incidentally my TR3A , which I've owned for 45 years (yes, 45) was built from new as a competition replica, the original equipment for which included an alloy sump. This really does aid cooling.

The reality is that many many things are not right or wrong..... plenty of scope for personalisation and all down to the owner - drive and enjoy :)

I guess what an owner does to their car is up to them. But when they come to sell the car it maybe not to everybody's liking.

 

Roger, The UN at present could have a job just for you.
