One question on serpentine belt that just shredded Sign In

I do not possess the skills to repair much on my 2001 Honda Accord EX.

On Tuesday my auto repair shop put on new bushing(s) and link(s) on the left front control arm (driver’s side) because of a squeaking noise in that area. On Friday afternoon I heard a strange new noise coming from the motor area of the car. I opened the hood and saw the alternator was not aligned correctly. I drove the car about 20 more miles on Friday and did not hear any more strange noises.

This morning (Saturday) my serpentine belt on the passenger side shredded when I started the car in the morning. I looked at the alternator and saw a loose bolt which caused the alternator to twist off center and the serpentine belt to shred.

I can come up with two possible causes for this situation.

First possibility: The shredded belt is a late result of the work of my brother (a very accomplished do-it-yourself mechanic who has a separate 2 stall garage for auto work) when he and I put on a new alternator over 6 months ago. Perhaps it took 6 months for the bolt to loosen enough to cause a problem.

Second possibility and my question: Is it possible the mechanic who put on the new bushing(s) and link(s) on the left front control arm needed to loosen the alternator located behind the radiator on the right front (passenger side) of my car to accomplish his work?

Your opinions and thoughts are greatly appreciated.

No reason to stop driving the car, right?

And people wonder why repairs are so much....................unbelievable

I honestly don't think that installing a control arm requires loosening the alternator. Instead of wasting your time trying to place blame, you really need to fix that problem.


The reason I say this is because you have a great chance of frying the PCM. Your probably thinking, "what is this guy talking about? How can a loose alternator cause this?" The alterator is grounded through its frame. If the bolts are loose, it is possible for that alternator to lose its ground. When the ground goes in and out while the alternator is operating, this sends large voltage surges into the electrical system. Those surges can fry solid state electronics. It is essentially the same as disconnecting the battery while the engine is running.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
