Ok, i know my couple rha sbeen bad for awhile and i've asked for details on the coupler replacement before but everyone always seems to post info for series 1 coupler swaps, i have a series 2, eithey way my main question inthis post is what else if anything should i do with the supercharger while im at it? im not looking to do anything fancy or expensiv,e just wanna know if theres any other maintenancy things i should besides the coupler

on the SC coupler change....

you dont have to remove the SC to pull the nose on the S2

remove the oil with a spray bottle
swing the alternator out of the way
remove the 10mm bolts that hold the Nose to the SC
and also dont forget to get the 10mm bolt that goes straight down into the LIM
after that the nose will come off

replace coupler, reinstall the nose with red gasket maker and then fill with 2 bottles of SC oil

and what of the 'gasket maker' i've heard of? will RTV work?

you NEED to get the GM RED gasket maker or Permatex when you put the Nose back onto the SC...

Go to a dealer and ask for "red gasket maker", they'll give you the magic red tube.

Permatex was not recommended. And I did try it. The SC oil was eating through it. Red gasket maker is the right stuff for the job.
