    The tension pully locked up and broke the serpentine belt, i called my local autopart store and they had both the pulley by its self for $20.00 or a complete unit for $104.00, i chose the pully by its self. due to that the tensionor was good, and i had now coolant leaks, it took me all of 20 minutes to replace the pully and the new belt, was not hard to do, after all is done the car is back on the road.
