Any help is appreciated. This is the 6th time I'm doing this job. The bolts for the fan belt tensioner mount keep breaking. I'm out of ideas. I have replaced everything. I've tried different grade bolts and even studs. I think the problem is with the metal surface you can see breaking away at the 2 bolt holes. If that's the case it will require a new engine as it is part of the block and not a cover. Any ideas or advice? The fan hub turns freely and is working properly. That's all this belt runs. |

One last thing. Does this truck idle with no surging at all? I had a 7.3 PS that had a ever so lightly surge at idle. You could watch the bet tensioner move back and forth with the surge. Eventually it would break tensioner/bolt off.
