Koyo Radiator Questions R32 GTR
I received my koyo 53mm radiator, this one to be exact: http://www.rawbrokerage.com/koyo-53mm-aluminum-racing-radiator-for-nissan-skyline-gtr-r32/
Looking at it, i am slightly confused. There are three ports:
1: Small port, looks like 1/8 npt, it came with a blocking screw already in, with a ton of teflon tape, I unscrewed it to make sure it was a npt port but the sender from the autometer gauges does not fit. So whats this port for?
2: Large port, looks like it would house an adapter for a gauge sender. both adapters from the gauges do not fit. Did not come blocked off. Is this where the stock sender for the car goes?
3. That's a drain plug, I'm not that crazy. lol!
Thanks in advance
