Yeah I ground off the place where the old engine hook was. it's got clearance there. It takes so much pressure its going to strip that notch on top you use a 15 mm wrench on. I saw a picture on crate engines and the tensioner looked like it had a hex bolt in the middle that keeps the 2 pieces together can anyone confirm this, because I def have a normal 13 mm bolt in there.

well I'm convinced someone sold me a ghetto rigged tensioner. I'm stuck at home watching my daughter right now. Anyone know the size of that bolt that holds the 2 pieces of the tensioner together?

Yeah I look like I do it easy but the initial force is quite high. There's a good bit of body weight going into pushing that down.

I do not think it matters if you have a allen, or a torx or just a 13mm bolt in that hole.

regardless it is a known fact the LJS tensioner is a pain in the ass to do. Go on cobaltss.net and you can read plenty of pleople having issues with it.

We used some vise grips. Others use a prybar.

It is really a crappy design.

Its not a crappy design. With a pry bar its super easy to do, WAY easier than the stock l61 setup.

I'm positive its was due to the wrong bolt being used in the middle of the tensioner. It was going through the tensioner and it came out the other side and was stuck. I need to figure out what size bolt to get to replace it... I guess thats what I get for buying used parts.

Thing is it was not designed to use a prybar on it, but a wrench. When you use a wrench you end up rounding it off. So yes crappy design.

I like the idea behind it but crappy.

I will take a stock L61 anyday over this one.

So I bought a new tensioner off of crateengines.com It was $150 shipped and will be here tomorrow just in case I can't find the right bolt. I'm going to think 2x about buying used crap again!

I'm thinking whoever had it had the zzp adjustable tensioner on it and lost the original bolt.
