Anyone know the torque value for this?
Okay, first I apologize for the lack of light in this picture.
I was fiddling with the serpentine belt and for some reason, the tensioner pulley nut felt loose ( It was 'cause I was rotating it the wrong way to loosen the belt :o duh). Anyway, I rotated it back clockwise (worked a lot better for relieving tension on the belt) but I wanna make sure that I torque it back to whatever it's supposed to be so that I don't have pulleys flying around at 5000 rpm. I can't find the torque value for it anywhere in my Helms. Is there one? Anyone know what it's supposed to be?
Thanks guys!

Is there any way to torque it more than just having it release tension? I guess you could jam a screwdriver in there somewhere that won't damage anything (just don't forget to remove it).
Isn't the rotational direction of the tensioner clockwise? If it is then it wouldn't be able to remove the bolt unless it shook it loose backwards...
Anyway, when I'm getting your lug nuts together in the morning I can check my helms and haynes manuals (I've got a non-ruby '93) maybe I'll luck across it...

I torque that one down to "pretty tight". Plus or minus "a little bit."
You won't damage the tensioner. It has limit stops to keep from overloading the spring.

Yeah, that makes sense... but I thought I'd ask just to make sure.
Thanks!

Threshhold... that's not where it breaks is it?
Also, for fine pitch, and threading into aluminum, torque settings are less.

Oops... duh! :o
Thanks, though. As soon as I learn to read, I'm selling the Vette!
