The Automatic Serpentine Belt Tensioner, No. 910074A, from Litens is a replacement part that meets all the characteristics of the original equipment part. Featuring a chrome-silicon steel spring, internal damping, a “lift-lug” feature, Tandem 6303 ball bearings, a molded locator pin, and a forged steel pulley, the belt tensioner fits many makes, models, and engines. The tensioner includes a heavy-duty, electro-deposited coated steel pulley for corrosion resistance and can be changed in roughly 30 minutes.
