coolant sensor in intake manifold

diymirage said
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

Try and make sure you can get the sensor down in the intake as far as you can get it.
Some dip shot put reducers on my engine to get the sensor to fit, and when I took all of them off and just used the right size in the first place there was a 10 or so degree diffence in the guage readings. (10 cooler than it really was)
Point is, apparently just not having the sensor directly in the coolant made it lie.
