    Never, ever ever ever ever use helicoil. I wouldn't even recommend Timeserts, only Normserts or studs

    Measure the depth of the bolt hole and then put the bolt in the tensioner and measure the threaded length that sticks out of the back of the tensioner. If the hole is deeper you might want to try getting a longer bolt, thats what worked for me.

    @DJSG3....is helicoils overkill?


    if doing helicoil insert, is there anything in particular that I should look out for or avoid altogether?

    Re: Time-Sert or Helicoil, which would be the better fix for a belt tensioner bolt ho

    OK some more info. Going on the info above, I measured the depth of the hole, and the amount of thread on the bolt on backside of tensioner. The hole is about, 1 in and I'm getting 7/16th when bolt is thru tensioner. It is an aftermarket tensioner. I took the same measurement with bolt thru tensioner with the original tensioner and I'm getting 3/4 length. So I tried the original tensioner but the bolt will not run up enough to secure the tensioner in place.

    So I'm guessing that just a longer bolt will not be good enough?

    Well that new bolt would only cost about 50 cents, so maybe its worth a try? Another cheapo option would be QuikSteel (steel-reinforced epoxy putty) to retap the hole, other than that helicoil or similar or insert I reckon.
