Tensioner bolt broke at the pulley! help!
Well, i went to change the alternator, did the usually, disconect batt, then go to the tensioner and get that belt off. Well as i did so, i didnt have enough play in the belt to get it off the alt, so I went alittle more then felt the bolt start to slip out of place as if it was loosing its torque inside the thread and then BAM hands went flying ratchet fell and bolt on the ground. I have the pulley/bearing off, and that little metal peice that serves as a big washer for the bolt on the end. What should I do? I looked an the whole tensioner assembly braket wraps around the whole 1 side of the engine. Maybe an easy out on the broken bolt

workin on a 350 tpi. The tensioner itself has a star bolt in the middle which I think If i unbolt will then shoot the spring and will be dangerous. It's very hard to get in there, I think I may have to pull the radiator to get a straight angle at the bolt. SO what do you mean? If I was to put a bolt in then I would put it in couter clockwise for it to screw?

The star bolt that holds the tensioner on will be REALLY tight. If you get a star tool at Autozone don't get the set of one-piece bits. THEY BREAK! Spend the bux and get the single bit the correct size. The tensioner (if it looks like this) is an assembly that won't fly apart. If you're not sure ask the parts guy to show you one (that's free).
It looks like this right?

and yes I was turning it left, So i dont get it. Why would they want you to turn the tensioner to the left to release the belt and then run into loosening the bolt by accident on the pulley.

Excuse me if I'm mistaken, but it sounds like you were turning the Torx bolt to loosen the tension on the belt? If so, that's a huge no no. As the post above me says, you need a 1/2 inch ratcher/breaker bar inserted in the little offshoot hole and then pull it left, or more precisely towards the passenger side. Once the belt is off, the tensioner should have no tension and then and only then should the torx bolt be removed to remove the tensioner.

yeah, not rubbing it in or anything, but thatta bees what the square is for. You get a hole lot more and reliable leverage against the spring, and your hands, and rest of your body that may come in contact with a flying tool will be much happier using this the right way.
Don't feel bad, at least you didn't give your self a black eye in the process. I had hours of fun with friend that did the same thing but wasn't furtunate enough to dodge the rapidly airborne wrench after doing the same thing

To clarify:
The bolt he broke is the bolt in the center of the pulley. Most of them are left hand thread. He was twisting it to the left (tightening) to release the tension on the belt when it broke.
The star bolt that holds the tensioner onto the bracket is right hand thread.

Read the first post:
He didn't have a 1/2" ratchet handy and just put a wrench on the bolt in the middle of the pulley.

What i understood was when he was loosening the pulley bolt the star bolt broke that holds the tensioner so it was just weak but he still was not doing it the correct way.

Nope didnt brake the star bolt spdfrk, u miss understood its cool. WHat i did was the bolt on the pulley itself broke when i tried to use that and go left with it to relieve the tension and that broke. So the pulley slid off on its own. Problem solved, I went to the junkyard and got a whole nother tensioner, just got on the star bolt and it came right off, wa hoo.

T-50 Torx bolt standard right hand thread. Take the belt off and it backs right off.

Re: Tensioner bolt broke at the pulley! help!
Sorry to jump on this thread didn't know where else to go I was trying to replace the tensioner star bit Bolt for a cleaner appearance with the rest of my ARP bolts but none will fit in the hole and be able to get a socket on it can you run just a longer bolt with a washer on the under side of the bolt head against the tensioner and it still be okay that way instead of having to use the star head bolt that just looks ugly black and rusty lol. just got through putting in a 427 and cleaning everything up in their wanted something nice ...thanks
