    New guy here. I hate to make my first post on a negative note, but I just had an interesting afternoon caused by a broken serpentine belt and thought I'd pass along a heads up. Anybody here ever had one break? Trust me - you don't want to. Steering? Only if your name is Schwarzenegger. Brakes? Forget it. Pedal right to the floor. I'd just gotten off a freeway and was only doing around 20 mph stopping for a light in rush hour traffic. How I managed to avoid hitting anything is anybody's guess. If I'd still been on the freeway doing 70, I'd have been in deep doo doo. I really miss the old V-belt designs where if you broke a belt, you lost ONE thing, not everything. '07 2500 w/5.9L and 51,000 miles. I check the belt carefully at each oil change - last one 2 weeks ago. Replacement interval is "as required" with inspection at 22,500 mile intervals. I think I'll just toss a new belt on every 30,000, because I sure don't want this nightmare again.

    My girlfriends dad has broken two or three serpentine belts on his 09 2500 with 100k miles as of today in the past 6 months
    He's had two different AC compressors went bad on him, bearings seized up and the belts snap shortly after
    Only thing he's really been mad about is having to have the truck towed...

    Yeah, the tow cost me $79, but I think insurance will reimburse me. I did have the AC going (it was 107 here today), but it was working fine. Tow truck backed my baby into my garage, so I can sort through the carnage tomorrow in an air conditioned building instead of laying in burning hot gravel. The belt is twisted up around the pulleys, and the fan blades have black marks all over them. I don't see any leaks or other physical damage. It could have been worse...

    Edit: The belt demolished the crank position sensor and rubbed insulation off 2 wires in the bundle that runs along side it. Gates belt - $48. Crank sensor $23. I got off cheap.

    So here's an update. I found what caused the belt failure. The bearing in the idler pulley disintegrated - completely. All I found was the inner and outer races, and both were full of rust. That let the pulley off the shaft, which took all the tension off the belt, then all hell broke loose. Gates sells a replacement with double bearings - Gates 36315 idler pulley for '03-'12 Turbo Diesel.-Geno's Garage. Dodge wants $140 for the OEM pulley with single row bearing.

    I hear that! I'm amazed I didn't hear that bearing failing before it completely let go.

    Towed a few for those pulley bearings seizing up. Most times not much damage thankfully.

    Wow, that coulda been much worse.

    I actually had that same exact thing happen with my old 05 Hemi. I was driving off base and all of a sudden the pulley literally blew up. Somehow, the belt stayed on and I was able to turn around and park it, even with the belt slipping.

    I wasn't as lucky. The belt was torn in half, slapped around and ate up the crank sensor. That caused the engine to stop, which made the power brakes inop. Another owner I met yesterday told me I was lucky the belt didn't rip into the radiator.

    I was very much confused as to how the serp belt took out your brakes, but if it killed your engine, that makes sense.

    Wow, sounds like quite a string of bad luck slammed into a short time frame!
