3 Serpentine Belts shredded in 5 days!
We are getting some trees cut at our house and I needed to move the ML. As I pulled into a spot, I noticed the battery light came on so i popped the hood and saw what was left of the serpentine belt. I yanked it out and could not believe it (NEVER saw anything like this before.) I drag ass out to Dealership and buy a new belt. I get the belt and pop it on, all is well. I decided to drive it to a meeting the next day and amazingly, ML feels like new.....until I get back and start to pull into the spot I left from, the wheel got heavy and the temp shot up FAST. I got into the spot and popped the hood, same thing shredded belt. Again to the Dealership, read some posts on here about similar problems check all pulleys and all seems well nothing seemed to hang when I spun them manually. I get the belt on and leave it for two days.
Yesterday I went to bring the ML back to my house and all seemed well I watched the belt spin for about 5 minutes with no apparent delays or freezing by any of the pulleys. I pull into the front of my house and battery, temp, and no power steering....I could not believe it third belt GONE worst than the past two.
How do I diagnose what is causing this without throwing parts at it. I have about 135k (11/1999 build date) on the clock and I hardly look at this truck these days let alone drive it. From my service records and the previous owners it looks like the only thing replaced in the pulley route was the Balancer. I saw there is a new tensioner part number to replace the old could that be it?
Thanks in advance for the help!
