You may need to use an "easy out," Drill a small hole in the center of the bolt, tap the easy out into the hole and using a socket wrench, try to gently back it out. Then replace it with a new bolt.

 

So the bolt is broken I was hoping it was just some aftermarket part, so it’s called an easy out tool or is that a term?

 

I just replaced my entire tensioner, that is so tight of a space to work in. Getting a drill and then easy out would not be a fun task. You could only drill if you had a right angle drill or attachment.

See if you can remove the entire tensioner, a couple more bolts and then remove the broken bolt with vice grips. (Hopefully where the head of the bolt snapped off, there's not a lip that prevents the tensioner from sliding off the bolt body)

 

Don’t I have to remove the 14mm bolt before I can remove the tensioner?

 

The Easy Out looks like a tapered drill bit, but the threads are reversed.

 

It’s gonna be hard getting a drill in there, would replacing the whole tensioner be easier?

 

Pretty darn easy to put on a new belt. It's very easy to find the routing diagrams online to make sure you've got it on correct. The tensioner is not difficult either. It's just a bit of a pain to get to because of how tight the area is. I just replaced my tensioner and when I did that I put on a new belt and it was about a 30-45 minute process.

 

If I cut the belt, you think I can just get a new belt or should I just at that point replace the whole tensioner?

 

With the broken bolt, you have no way of relieving the spring force that tensions the belt so you would not be able to get the new belt on. And without that bolt you have no way to relieve the spring tension to get the old belt off either. You're going to have to remove the tensioner one way or the next, and since the upper bolt is broken, you really have to replace that tensioner so that you can even get the old belt on if you choose to reuse it.

 

Ok, so replacing the tensioner is necessary then.

 

It looks like this one

 

In 2006 Honda released a front wheel drive Pilot and it does appear it uses a belt tensioner uniquely different than the AWD version. If yours in FWD then you might not have a broken bolt at all.

 

Yes it’s FWD, are you familiar with. The FWD ones?

 

This:

 

is it a 19mm socket to loosen the belt, I’m trying to change my alternator so I need to loosen the belt.

 

I do not know what the size is, sorry.
Just take a socket and see what size it is.

 

I really don't understand why people try and tackle these jobs without first referring to the factory service manual which can be found on this forum.

 

Hey just a update guys, I finished the job ran into a BUNCH of problems it isn’t perfectly done but I believe I did it, I literally HAD to change my belt tensioner because it was broken and the belt seemed worn and loose, so I replaced that, can you guys let me know how it looks to yall.

 

I would have just cut the old belt and used an angle grinder to cut off the old pulley.
