Why won't the serpentine belt stay on my 2001 dodge stratus
Old belt came completely off...or was gone...got a new
serpentine belt and got it on...but as soon as I start my car...it
slips right back off..even after tightening everything back up..
Possible oil dripping on belt.
It might be an idler wheel that is worn or loose and no longer properly aligned.
Idler tentioner bad.
Possible oil dripping on me.... you are too hot to keep it on....
Bad tensioner, idler or harmonic balancer. Most likely the tensioner spring is bad or the bearing is bad.
