sorry, i forgot to mention...its for my 1990 k-1500 4x4 with 5.7 engine.
just curious if any oil will leak when i pull the original one out, and if i need any thread tape/sealer on the threads ?

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.
