SC coupling?

[Dadkota]

I'm about to do my pulley swap (finally) and somebody told me I should do the SC coupling while I'm at it. My car has 172k on it, I don't hear any strange sounds or anything. The SC oil is good, I checked it very recently. Should I do the coupling along with the pulley? Im only asking because I'm in a budget and would like to avoid cost if possible.

If it's not loose, don't worrry about it.

Any way to tell if it's loose other than opening the snout up? Does it make a noise when its loose?

take the belt off, grab the sc pulley and snap it back and fourth, if its got play you will feel it click

 

[Dadkota]

Snap left/right/up/down? Or forward and back?

 

[Scottydoggs]

spin the pulley one way, then snap it back the other.

So maybe he could take a can of Carb cleaner to his vacuum lines and spray all the lines while the car is running & check for a leak. Feeling like, based on what he said he's done recently to his car he has a vacuum leak.

I didn't think anything was wrong, someone just said to do it because the pulley would be off anyway. I would rather not do it lol just want to know what other GP people had to say
