Engine Mechanical problem
2000 Pontiac Montana Two Wheel Drive Automatic 147000 miles
My serpitine belt came off.I put on new one and when I started it up the belt came off.I noticed when I went to put belt back on that the crankshaft pulley is not inline with the rest of the pullies alt, aipower steering. What would cause this to happen?
I have just experienced the same thing today. Any ideas anybody

You crankshaft pulley could be loose try torquing it to specs and inspect the other pulleys double check belt tracking/alignment

In another forum I found many Montana's where the Harmonic Balancer has come apart which is causing the pully to be 1/2" out of alignement so I will check this now. Thanks everybody.

What were the results? I have a similar issue with the same year/make/model.
Thanks for any info.

I had the same problem and the harmonic balancer (102K miles)had actually started to separate and caused the pulley to move forward. Oriellys to my surprise had it in stock so I suppose it is a common problem. At the same time I found everyone of the idlers/bearings(there are a few) were wore out so I replaced them
