thermostat housing help - 79 k10
Hey guys I need some help here, im replacing my thermostat housing on my 79 k10.
I did some searching and did not find what I was looking for. It has the 350 in it and right now it has one of those chrome thermostat housings on it. I got my original replacement and it has two holes on top of it. One is threaded and the other is not. I have seen that the EFE sensor goes in the threaded one, how about the hole that is not threaded? Thanks for any help. Here is what it looks like:

Re: thermostat housing help - 79 k10
so I replaced my thermostat housing and both holes were threaded, so i just put a plug in it. So both holes are plugged. Would still be good to know what both are for. Thanks!
