How to remove serpentine belt tensioner assembly?

[JFP in PA]

The tensioner assembly can be removed with the engine in the car; there is just a lot of stuff in the way. And, I finally found a diagram for you:



#10 has to come off before the arm, #8, can be released and removed to get at the problem bolt, #6. But as #10 is on the back of the housing, all the other aforementioned stuff has to come off first.

Thank you very much for that. Looks like this is going to be fun...

That is why I suggested trying to screw it back in and leave it alone.............

What would you think about cutting out that bolt completely and then using a new bolt going through from the other way? So...it would go through from the front of the pulley first (threading through it) and then I'll use a nut to secure it on the back side of the lever arm. Why do all this? Because the head of the original bolt that's in there right now is really chewed up and I'm trying to avoid pulling that whole assembly out at least until the next time I drop the engine.

I suppose it might work, at least for a limited time frame. The OEM bolt literally forms a stud that the spacer, idler and its front nut tighten onto. What ever you use would need to be of good quality (e.g.: grade 8) as you do not want the belt load to cause it to deflect off axis, which could also lead to issues with the serpentine belt not wanting to stay on. As the OEM bolt was originally a “micro encapsulated” fastener, you would also need to use LocTite on the threads to make sure nothing loosens up.

Before I begin I would like to thank this forum for all the help I have gotten on previous projects. My new project is replacing Part# 997-102-260-00-M260. JFP, Do you know where I can find instructions on how to remove the Tensioner assembly? I don't have the OEM service manual and so far searches in google have been unsuccessful.
Have a good one all.
