I'm looking to install a new electric fan for my 69'. The temp sensor for turning it on/off needs to be threaded into either the intake or head. My question is, what type of sealant should I use on it, if any. The instructions (yes, I read them) said not to use teflon tape. I assume this allows the sensor to ground itself to the engine. Thanks for any help.
