A pulley that turns all the belts fell off my car this am.?

Yes, they most definitely should repair this under warranty. If it's the dealer's fault that it broke because they didn't torque the bolt for the crankshaft pulley properly, then they should pay to fix it.

Most of the time the timing belt is seperate from the serpentine belt. The serpentine belt is what controls your power steering pump and alternator while the timing belt crontrols the waterpump and the timing of the engine if the timing belt breaks it can really mess up your engine with bent valves and other serious engine problems while the serpentine belt will just not let your battery recharge while driving and cut off your power steering so if they did work on the serpentine belt then yes its their fault make them fix it but if they only worked the the timing belt then I wouldn't be there fault although they should have checked everything while they were under the hood

It sounds like something that you should file a complaint with the BBB as that Dealer is at fault. It sounds like your Water Pump pulley or the timeing belt pulley. Both would cause you to have most of your problem as the belts control the Power Steering, Alternator which in turn would turn on your battery lite. In a lot of States if after 3 times of trying to fix a problem the dealer has to eat it,,,,,,,,,,,

If the bolt came loose and the complete pulley fell off, yes they should warranty it plus give you new belts because the old ones wore when the pulley came loose. There is another common problem with those pulleys, they separate and the outer ring walks off! That I would expect you to have to pay for.

It sounds to me like they've over torqued it! That's basically over tightened it. If they've done this then yes they should fix it but tbh from the way you described previous work I wouldn't trust them with my pushbike! I'd tell the garage what's happened and that you're far from happy. Also tell them you expect them to know the torque settings in future!

If you aren't happy with the work carried out tell them you are going to go somewhere else to get it fixed and that you will charge it to them. You won't be able to drive the vehicle, don't even try the key to start it as with no belts that could do untold damage.

michael is a moron. the crank pulley most certainly has to come off to change the timing belt.

Bolt was over torqued, good luck proving it though. either way...not too hard to fix.

Yes, it was the shops fault.

Take it back and get it fixed, I would refuse to pay the repair if they want money..

No, changing the timing belt, which doesn't have anything to do with the serpentine belt, wouldn't have caused this problem.

There are two belts.
