Sigma Radiator leaking - Recommended replacements?

[Mr Kipling]

I'm looking to replace the standard (plastic end tanks) rad on my sigma roadsport - leaking where the tanks are crimped, which appears to be a fairly common problem...?

 

I've been looking around and so far have only seen the Caterham ali end tanks one (which has me wondering if its going to leak too?) and a Radtec one (looks pretty good but unsure as to whether it'll fit straight onto a sigma car? )

 

Anyone found an alternative or recommend either of the above? - Planning on some engine upgrades too in the near future so would prefer to have a better quality and more efficient rad ready and waiting.....

I think this has been raised before and alternatives like Radtec mentioned.

 

I am on my third rad in my Sigma in 6,500 miles, second gearbox (plus a further re-build), new rev counter, ARB, wheel bearings, re-map and more.

I'm on my second radiator on my Sigma 150 but when it goes again I will get one of these Radtec ones

Yup raised this the other day. Will be giving Radtec a go I reckon once I've figured it all out. It's basically the same price after all. Might get some silicone hoses at the same time... Hm.

I went straight for the Radtec option when my CC rad died (Sigma 150) and have been very pleased with it's build quality and performance.

Cheers for the replies, Radtec it is then...
