I went to Dorman and found the plugs. The numbers I found were a little different Brass 566-036 and Steel 556-036. I also saw Copper, Neoprene, and ribber the same size. What material might be the easyest to install? Why so many materials? Different freeze points? We don't get hard freezes here.
You call for good sealer, what is a good sealer?
Thanks again!
