    I can't remember exactly, but I don't think anything leaked out when I changed mine in my '91 Z71... I swapped out the vacuum style actuator with the electric style... And I don't believe I put anything on the threads either... But it was a long time ago... Sorry I couldn't be more help...

    put my new one in today. wow, how easy it was. only a very little bit of oil leaked out, probably what was on the switch. cleaned the threads and mounting surface with brake cleaner, and put a little bit of permatex blue sealer on the mounting surface face,a nd tightened it up.
    hope to give it a try this weekend.
    thanks again./
