Looked around, but couldnt find much info on the subject. I just had the blade come off my electric fan and punch a hole in my radiator. Do the TII and the N/A use the same radiator? If not whats the difference?

 

As far as I can tell in the 6 years Ive fooled with these, theyre the same within series...s4 are different from s5 though. Some s4s had a rad. cap, some didnt, the ones that do, I just ignore it and use the one on the engine. Sometimes, due to swapping these out, you have to alter where the overflow line went to, and swap radiator cap housings on one or the other to eliminate a spare nipple, or to give yourself a nipple where you used to not have one.

 

Yeah, I had to relocate my overflow tank because of my fmic. But knowing theyre the same helps me find one easier. Thanks.
