i use standard rad (brand new) and a GRS with a huge fan at the front...


also use standard thermostat and fan switch...

car used to have over heating problems and it cudnt b solved, an ally rad was tried and everything.... (b4 i bought car)

wen i changed bottom end i changed all gaskets including water pump...

found pump was same as 2i 1 but not same as the fezzy turbo 1 i was puttin in (2i 1's blades had like a plate over front of it) 1 in new engine had open fan blades...



never have problems with over heating since!
