Dorman 419648 Drive Belt Tensioner Pulley

Dorman's Belt Tensioner Pulley is engineered to maintain tension on the serpentine belt for the life of the belt--thereby keeping the alternator charging, the water pump running, and the power steering pump and A/C compressor operating properly. They feature a high-quality double-sealed bearing to resist damage from contaminants. Replacement prevents belt slip and eliminates squeak, squeal or groaning noise associated with a worn belt tensioner pulley.
