Temperature Sending Unit
I'm going to replace the water temperature guage and sending on my Atomic Four. What is the best product to presoak the sending unit for a clean removal and what is the best product to treat the threads when installing the new sending unit?
I find that PB Blaster is not particularly effective for stainless steel screws in aluminum, but have not used it on brass to iron fittings.
I appreciate any advice you might have.
