I have a 2001 Honda Civic LX and I changed the timing belt and on the tensioner the bolt wont tighten up cant even get close to 33lb. When I took the bolt out it has shaving on the bolt. I tried a new bolt but it just slips when you start to get it tight. Small area to work in too I need help Thanks

Your best and I believe only choice is a Heli-coil, if installed correctly you should have no problems.

Thanks you for that Where do I get that at? How do I know what I need size for that bolt? When Im done that will give me the right bolt size for the tensioner bolt? Thanks

Ugh, no. That would be your very last resort. Try to re-tap the thread with a tap and die kit from Autozone, Pep boys, Sears - 30$ That is your best choice.

Google how to use a tap and die, its cake.

You cant use a tap and a die, the threads are gone in the block, heli coil is the only thing you can do. If you could use a larger bolt then you could drill it out and tap it, but theres only one size bolt you can use in the tensioner.

Take the tensioner bolt to napa, ask them for a helicoil kit for that bolt. I had to get an m8x1.25 once and it was $45, but totally worth it. It'll give you instructions on how to use it, but more than likely youre not gonna be able to get to that hole with a drill if the engine is in the bay, if you cant get a drill, use a t handle and do it by hand.

Basically what youre gonna have to do is drill out the hole with the provided bit. then tap it with the provided tap, and then insert the heli coil with the provided tool, and then you trim the helicoil if necessary and break off the tang, and youre done, be sure to get a new bolt from honda.

If you dont feel comfortable doing in yourself you can call and ask a shop maybe, but youd have to tow the car there.

If its only shavings it may just be a few cross threads, I wouldn't drill that hole larger until I've tried tapping it first. Like I said last resort.

I dont mean to be rude, but thats not gonna help either, the bolt already has stripped the threads to where it keeps turning in the block. If it were just a few threads running a tap still wouldnt help at all, sticking a tap in there, which is just a different cut on the exact same size bolt and thread pitch wont help since theres nothing to cut into.
