Would you guys advise using teflon tape on the brass bushing that screws into the cylinder head for the temp gauge ? Also, the brass threaded plug that holds the sensor wire, teflon or no ? I've read different opinions on the subject. I think not...
I just don't want a coolant leak down the road. Thank you !

Teflon tape for the most part is a thread lubricant but will fill in minor thread imperfections .this is a 1/2 inch pipe thread connection The thread itself is tapered and is designed to seal on the thread faces. If cleanned up and in good condition it shouldn't need the Teflon tape .

The threads cleaned up good. I'll abstain on the tape, for now. Appreciate the input.

I used a little pipe "dope" that is used on gas lines (natural & propane gas). No leaks and the extra is wiped away. Helps on removal if needed also.

I would add one serious note of caution. IF you use Teflon tape on automotive DO NOT USE WHITE TEFLON. It will dissolve in petroleum base products, oil, gasoline, etc. You must use YELLOW TEFLON TAPE, which was specifically designed for petroleum based products. That is one of the reasons Teflon Tape gets a bad rap for clogging carburetors. People use white Teflon and it dissolves then feeds into the carb and plugs small orifices. Yellow doesn't do that.
