Dayco Replacement Auto Parts Tensioner sku-3476963519

Dayco drive belt tensioner assembly, sku-3476963519, UPC 463476963512, is a Replacement Auto Parts item measuring 8.07" x 4.47" x 4.22". It is listed as an exact OE replacement compatible with the Ford F-150 4.9L L6 from 1987-1996. The assembly routes and tensions the belt for accessories such as the air conditioning compressor, alternator, power steering pump and water pump. It is designed to reduce belt wear, friction, vibration and harshness. Smoother surfaces and tighter dimensional tolerances are intended to extend belt life; the bearings are lubricated, the seals resist high temperatures, and the assembly is made to tolerate dirt, salt, chemicals and under-hood grime. Dayco also makes timing, serpentine and drive belts and dates its belt business to 1905. The company describes its drive-system products as intended to support engine efficiency while reducing noise, vibration and harshness, and says it aims to anticipate customer needs with reliable parts and services.
