Very curious. Seems like the SRT6 belt tensioner pulleys aren't available anymore. What do you guys do once it wears out?
Can the N/A one be substituted?
Also have heard split opinions. Do you use the E10 torx to release belt pressure or a 15mm socket (the screw behind the torx)?
I tried the 15mm and am afraid I actually loosened the tensioner? Might be in my head buts it has a slight wobble and had too much play imo.
Should I tighten that 15mm screw or should I tighten the 2 screws that hold it in place?

But more importantly, if these aren't to be found new anymore, what are you doing if it breaks?
