{"product_id":"accessory-drive-idler-pulley","title":"Accessory Drive Idler Pulley","description":"The Mercedes-Benz drive belt idler pulley, part number 0002021619, is a direct-fit component designed to guide your vehicle's serpentine belt and maintain proper tension.\n\nThis grooved idler pulley plays a crucial role in the accessory drive system, working in conjunction with the tensioner pulley to keep the belt properly aligned and taut. It assists in routing the belt around essential engine accessories such as the power steering pump, water pump, alternator, and A\/C compressor. It is often recommended to replace the idler pulley concurrently with the belt tensioner to ensure optimal system function and prevent premature wear.\n\nSymptoms of a failing idler pulley can include visible wear or grooves on the pulley surface, belt squealing or chirping noises, grinding sounds from the bearing, uneven belt wear, or pulley misalignment. This pulley is specifically designed for use with the 1.8L L4 M271 engine, fitting models such as the C250 (2012-2015) and SLK250 (2012-2015). Always use the vehicle selector to confirm fitment for your specific application.\n\nThis product is backed by FCP Euro's Lifetime Replacement Program, offering coverage for as long as you own the vehicle. Please note that oversized and direct-ship products may be excluded from free shipping offers.","brand":"Mercedes-Benz","offers":[{"title":"Default Title","offer_id":52689031823672,"sku":"0002021619","price":17.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687380168.jpg?v=1784900805","url":"https:\/\/store.motormia.co\/products\/accessory-drive-idler-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
