I buy a sweet all aluminum champion radiator thinking it will be bad ass. I go to install it and the overflow fitting on the radiator is for 5/16 id hose while the tahoe takes 3/8 id hose.
So I say ok no big deal I am a machinist I will just make a new fitting or maybe I can just buy one.
I start looking into what the thread is on the champion 5/16 fitting..... hmmm it is very tapered, too tapered. I call Champion and they say it's a 1/16 npt.
I am machinist so I know the included angle on a ntp is about 3.5 degrees. Well I check the angle of this thread and it is a whopping 12.5 degrees!!!!!!
So either they are making a proprietary thread and lying about it or more likely some bungler make a few thousand of these WRONG and champion instead of throwing them away decides to just let their customers jam this part in there.
very disappointing
