coolant sensor in intake manifold

so guess what sealant they have at my local autozone ?

yup, the high temp one

that and some stuff called "indian head" (also made by permatex) which the clerk said was pretty good too

I guess ill look up a few other places

I did manage to get the temp sensor drilled out to a 3/8 hole and there is still a little bit of brass there so I don't know if it had an insert or if it had been drilled out and overtapped before but im going to see if I can get a 1/2NPT to 1/8 NPT reducer and just slap that in
