{"product_id":"70mm-serpentine-pulley-6-rib","title":"70mm Serpentine Pulley, 6 Rib","description":"The Dayco idler pulley (Part # 89015) is engineered for the majority of automotive vehicle applications, offering a direct fit replacement for worn serpentine and V-belt drive idler and tensioner pulleys. It features premium lubricated ball bearings with double high-temperature seals, ensuring peak bearing performance critical to the pulley's service life.\n\nWith a diameter of 70 mm and a width of 28.3 mm, this 6-groove pulley is compatible with a 06 Rib belt. The inner bearing diameter is 17 mm, and the total bearing width is 12 mm. While it meets or exceeds OE quality standards, some user feedback indicates that while the pulley may appear identical to other brands, there can be variations in perceived quality. One reviewer noted that the pulley's interior can rub on the tensioner due to its construction, and that OEM pulleys are typically metal while this model is polymer.\n\nSpecific fitment details indicate that this pulley is compatible with various GM Silverado\/Sierra 2500HD\/3500HD models with the 6.6L Duramax engine (LB7\/LLY\/LBZ\/LMM), and C5500 models, provided they have Air Conditioning. It also fits certain Dodge Nitro 4.0L V6 models from 2009-2010. However, it is explicitly stated that this pulley does not fit a 2007 Dodge Dakota with a V6 engine, as it is an alternator pulley application. Installation may be tight on some vehicles, such as the Ford Windstar, potentially requiring prying and shimming for easier removal and installation. The nut and bolt are not included with this pulley.","brand":"Dayco","offers":[{"title":"Default Title","offer_id":52687609528632,"sku":"89015","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687895660.jpg?v=1784885600","url":"https:\/\/store.motormia.co\/products\/70mm-serpentine-pulley-6-rib","provider":"MOTORMIA","version":"1.0","type":"link"}
