WRX/STI Radiator differences
 

Just wondering what differences there are between a WRX & STI radiator, & if they are interchangeable. My car's a WRX 02 Bugeye.

they are interchangeable.
the only major difference is that the later gd sti radiators have a filler neck, so you need 2 radiator caps.

So if I use a STI radiator do i need to get a plain cap for the radiator & keep the pressure cap on the header tank, or put a pressure cap on the radiator & use a plain cap on the header tank.

they use 2 pressure caps as standard, a round higher pressure cap on the radiator and a standard "eared" cap on the header tank.
the 2 overflow lines are "t" pieced together before entering the overflow bottle.

Cheers for the info.

I can find plenty of the eared caps (STI 1.3bar) but Im having trouble finding any of the round caps (haven't tried a subi dealer as they generally ask for a vin number for thier parts system). Any information, eg: part number or vendor to try would be appreciated.

maybe give rossco a pm, he's the master of subaru part numbers ;)

could someone please confirm with me that this will fit my04 wrx
