[Fot] Aluminium radiators

I just upgraded my TR4 to a Griffen. The common circle track size is too tall to mount straight up but they sell a shorter version. I modified the Griffen universal brackets for the bottom, to put the radiator in front of the original mounts and made up an air box out of some tubing. Pegasus sells the hose adapters. PN in the pictures below.

>> Hi - I'm not 100% certain about the thermal properties, but I'm certain that cost was a major part of the engineering decisions to use copper / brass back in the day. But for street-driven cars, copper / brass is superior for a lot of reasons if you leave out the weight as a factor. It's also more "forgiving" to road debris and flex than aluminium. For a race car, it's no brainer to use aluminium. Way less weight and they usually come with thicker cores and more "rows", hence better suited for the application. Aluminum does have a limited service life, but you can extend that with proper maintenance (flushing the system frequently if you use plain water as the coolant) and checking for cracks / pressure testing (catching problems before they become big problems).

>> We have good experiences with Wizard as well. They have been reliable and the quality is very good. As some people feel that oil coolers are a consumable a item, our research indicates the same may be true for aluminum radiators in cars with cast iron blocks. There are things that can be done to help them live for years. However, they eventually need to be replaced due to the relationship of cast iron, aluminum, water and electrical current.

>> Also, I would say NEVER run any type of coolant stop leak product with an aluminum radiator, especially with an iron block. You will plug the radiator very-very quickly. Not to mention the mess the stops leaks product makes where your block and head ports are supposed to be able to move coolant. If you are swapping fluids, find the leak and fix it correctly.

I had them duplicate the dimensions of one I got twelve years ago from an outfit that went out of business. They copied it perfectly. About a 6-8 week leadtime, maybe less if you are getting off-the-shelf.

>> My one concern about aluminium radiators is that most of the time you can't fix them, so if you crack them, it's in the bin for 'em. Copper / brass is more forgiving. Ally does have the "wow" factor, though.

>> Where are folks getting (street) Al radiators nowadays? Just got the original TR6 rad back from the local radiator shop with an estimate of ~$360 to re-core, re-cap the lower end, and get rid of all the acorns the squirrels have thoughtfully stashed in mine, so I figure it's probably cheaper to get a new Al one than press my luck with the original.
