thread sealer for water temperature sender
91 ranger 4.0 ohv
I removed the water temperature sender (1 wire sender) and the Engine coolant temperature sender (2 wire plug) from the lower intake manifold to clean the manifold while I am doing a valve job. What kind of sealant should I use on the threads while replacing them. I know for the one wire sender it reads the variable ground between the threads of the sender and the one wire. The two wire sender I am not sure if the threads need to be grounded. I am thinking the sealant needs to be able to be conductive as well as seal well and high temperature. I thought of using teflon tape or paste or permatex high temp thread sealant but does not seem like it is conductive. Anyone know what to use.
I have a Ford manual and this is what it reads:
Use D8AZ-19554-A (esg-m4g 194-a, esr-m18p7-a)
Pipe sealant with teflon or equivalent or small amount of electrically conductive sealer.
