Hi Tinks
Radtec or ACT.
Think mine came from ACT via RT.

Yes Jonathan's right.
Changed to read Radtec. ACT one is a little cheaper looking at them again ..

I have a Radtec one in my V8S and it has been fine for a good few years now, fitted well, no leaks. Maybe that's what the previous poster meant when he said Racetech???

Looking at that, they now also do a fuel tank. Hmmm!!!

Hi Tinks,
I can't do links, but if u PM me ur email address, I've bookmarked an Ebay item that may be of interest to you that I could send details.
You'd need to check the dimensions, but someone has fitted this rad to an S.
It's for a Scooby Impreza Version 1993.2000 WRX Sti from 2fast2cool, based in Lancs, so not too far away. £140 + 7.95 pp

A recore will cost about a third of an alloy rad and last another 20 years but not look quite as nice.

Have you been following BarryS1 too close?

Thanks Mike,
You've just saved 1/2 an hour of my life!

Tinks worth considering that I don't think an ally rad can be repaired - so if you get stone damage like you have now its a new rad again!

Hi Paul,

the present cooling system being all steel (and a bit of rubber), I would not add another metal to it.

The alloy, let us say alumimium, being less noble then steel would suffer most.
The rad will be earthed to the chassis via the mounting bolts, and so is the engine via an earthing strap.

According to http://en.wikipedia.org/wiki/Electronegativity there is .2 V driving aluminium corrosion.

A few engines have steel blocks and Aluminium heads of course.
They then have very special requirements for coolant chemical composition.
You would have to follow those recommendations.

The weight saving would be something like (7.8-2.7)/7.8 * (rad metal weight =15?) kg = 10 kg.

Its a V8... alluminium engine

Shouldn't be earthed, if mounting is same as V6 its on rubbers.

oops, sorry. I have a V6.

Then the reverse is the case, everything Al, and an alloy rad would jive with the rest.

I happened to lift my own rad out of the car just today, was surprised how light it was.

The weight was just based on difference in densities.
Not counting that Alu tubing might need to be heavier gauge then steel ones.

Easy mistake (but the clue is in the ops name)

Steel? aren't "standard rads" copper and brass?
