So my hubby's 200 limited, got new idler pulleys and a tensioner pulley, with the second new belt in under a month. Got it back on Sunday, Tuesday afternoon we were checking fluids and noticed the belt is starting to rip again. Any ideas what else might be wrong?

 

The pulleys are probably not aligned properly. Take it back and have them check the pulley alignment. Make sure the belt isn't being touched by some stray part that is out of place.
