anyone know where i can find a alloy radiator for my te, cant find them for a magna or diamante any radiators that will fit ???

Have you tried the radiator specialists like Natrad, Red devil etc??
Otherwise you can try Burson auto parts or even Repco or Supercheap Auto.
I've also seen plenty of new aluminium radiators for magnas on ebay. Mitsfix (AMC member/admin madmagna) sells mitsubishi magna parts on ebay also. You can find him in the members list & PM him.
Failing that, your local Mitsubishi dealer.

im looking for a full alloy radiator

Do you mean alloy end tanks as well, as they would be hard to find? Copper cored units are very rare now anyway - mist are aluminium with plastic end tanks. I bought a new Fenix alloy radiator for my Ralliart 6 months ago. Good quality, bolted straight in. Kiwi brand

I checked the Fenix site. They do full polished alloy units but only for a few select performance cars - like Evos. So they are out there.
