Another broken idler pulley bolt!!!

Okay here it is... My 2007 ford focus 2.0 has broken the drive belt idler pulley bolt again.. First / original bolt broke at 50k. Sheared off at the block... I replaced the pulley and tensioner as well just incase that is what caused the bolt to break... 2-4k miles later it broke again..talked to another tech at our ford dealership and he had the same thing happen to his focus... His is still breaking them too.. Then I decided to replace it again and upgraded bolt to grade 8 in the metric system... Also used lock tight and nut from the back side incase it was backing out an causing it to break off.. Well it broke again today 3-4k miles later...it always happens on start up.. I hear a squeal pop the hood and see the broken bolt.. Ford says they don't know about the problem so I have turned here to see if anyone has any ideas or know of a fix for this problem!!!
I hate to say it but if this next time it's not fixed for good I will be trading in on a new fusion!!

Adam, I have 07 Fusion and have am having same issues. Mine has broken 5 times! Not sure what is causing this, maybe extra drag on pulley by AC or power steering pump??? I tried putting nut on back of bolt with no luck. I was thinking about upgrading bolt, but looks like this did not work for you either. Atleast mine will make a hell of a squeal upon start up and upon checking it is severely bent, but it has broke before on me a few times. I believe the bolt is way too weak. Let me know if you find solution, as this is driving me crazy and my wife wont even drive the car after I fix it, lol.

The ford engineers said that wear to the front cover where the idler bolts down will cause repeated failures... Mine has the slightest marks so I will be replacing the front cover.... If this doesn't fix it I am done!!! The real question is why did the first one break?? I will let people know in a few thousand miles!!

Hope this works out for you.

I know this would just be a bandaid and not address the real problem, but you could always upgrade to a grade 12.9 bolt. I am pretty sure the sheer strength is about 30,000PSI stronger than a grade 8 bolt.

Anyone know where to find this grade 12.9 bolt?

Since you're in Washington. Try Tacoma screw. They have several locations around the sound. Fastenal is also a good source, but tends to be pricey. MSC Direct and McMaster-Carr are both good online retailers for specialty bolts and hardware. Finally there is ARP. I'm sure they've got something that's stronger than grade 8 in your thread.
