new rad
Valtra - 27/12/13 at 01:36 AM

Merry Christmas all

Had a long running engine rebuild and Microsquirt conversion on my old Fiat Twin Cam . during my last entries on here I was having overheating problems which I eventually traced to a blocked rad . After a few sessions with Sulphamic acid the car was finally running cool again (looking back it had been getting hotter before the rebuild) but the acid had eaten too much and left pin holes in the rad I had been running a rad that matched the engine from a 131 Supermirafiori however they are now very rare and I've been scouring the internet to find a rad that will roughly fit the same space have the same size 35mm inlet/ outlets in roughly the same positions . eventualy come up with a Mazda 323 unit that is the closest but it is mega thin at about 18mm . Now I know that Westies and several others use a humble Polo unit , I don't live in the tropics and my lightweight car rarely stresses the engine and has good rad air through flow . Also I'm not pushing big power out (around 120 bhp ) so would this fairly low capacity rad be adequate ?

cheers

Copper-brass radiators can be re-cored, there are still a few radiator repair workshops around.

Dont see why a polo rad wouldn't work they run much more powerful engines.

Just depends if the outlet positions suit your engine. You can also get alloy versions that are thicker. I've just fitted an alloy honda civic racing radiator that thicker but then I'm running 250bhp turbo

This one is good value and a larger core

Yes, been looking at civic units, as Polo is too wide for my narrow chassis . Civic has 28mm unions so needs some fiddling to step down from 35m fiat

Interesting but not sure how Ebay works in Italy doesn't look a familiar format

You are no doubt correct I've looked at too many , still it would need a good sleeve to fit tight , also the civic units don't seem to have a tapped hole for a fan switch either, more complication

found a heavy duty version of the Mazda 323 unit that was fitted to the highest power Automatic version which has a double thickness core , correct size inlet/outlet in roughly the right place and a drilling for a switch. even reasonably cheap from Mr -Auto at about £75 inc vat and carriage. should be well up to the job.
