I had aluminum cooling pipes installed a couple of years ago, shortly after I bought my F-Type (due to catastrophic failure of the plastic Y pipe). I was not in a position to do the work myself at the time, so I had a local indy shop do the work. They checked the SC coupler and didn't find any issues, so they reinstalled the SC without changing the coupler. Two years and ~6000 miles later and now I am getting the "thunk" on shutdown and there is play in the coupler. Is there any way to change out the coupler without going through the full process of removing the supercharger again?

(Yes - In hindsight, I know I should have had the coupler changed when the SC was off the car, but I wasn't aware of how prevalent the issue was and the shop didn't think it was a problem.)

 

I went as far as possible with the SC still installed, but the lower coolant Y-pipe blocks access to some of the lower bolts of the SC snout. Maybe someone has a technique to remove them from behind the y-pipe, but I needed the Y-pipe off anyway. I ended up removing the SC.

 

Hi! Old post but did you manage to change the coupler without removing the SC? I'm in the same boat right now. Thanks!
