coolant temp sender sealant
ok, guess i missed temp and fuel gauge day here on fte awhile back. seems that you can't use teflon tape to seal the coolant temp sending unit cuz it is an insulator and not a conductor. after consulting my manuals and searching this forum i still am at a loss as to what type of sealant to use that would be considered a conductor. can anyone recommend a good sealant that is a conductor? what does ford specs call for?

The threads on temp sensors are pipe threads.Which are cut to be self sealing.But I always use teflon tape,And have never had a problem.If your just wrap it around the threads and not the top or bottom edge.No matter what the sensor will bottom out and contact metal or the top will seat flush and contact metal.

I've always used the liquid teflon although lately I'm hooked on some new copper sealant I bought at Napa. Either way you're going to get ground, even if you wrap the crap out of it with teflon tape.

The rule about not using Teflon tape was caused by a number of instances where the Teflon tape did insulate the sender or changed it's resistance. Use the liquid pipe dope that is specified for the application by the repair manuals. The standard Teflon type liquid pipe dope that comes in a tube or brush-on container from the local hardware or home box store is OK.

that's what i'm looking for - anyone know what this stuff is called, my manuals (both haynes and chiltons) say nothing about sealant.
ivan - is that stuff you got at napa called copper coat? i've used that stuff at work a few times when installing rigid conduit. was it kind of expensive?

Is there anything wrong with just using regular high temp silicone sealant on the last 1/2 of the threads (closest to the bolt head)? This seems to want to seal everything else in the engine, so why not threads? Does it make it hard to unthread them?

Threads shouldn't matter...

There is also a problem with some brands of Teflon tape. Some of them have a plastic base tape with a Teflon coating, usually the real cheap stuff. That type is very likely to insulate your connection. Use the pipe dope and be done with it.
