This is the Genuine Mercedes-Benz OEM serpentine belt for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores full accessory drive function with factory-spec dimensions and construction.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat This Part Does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe serpentine belt is a single continuous poly-V belt that wraps around the crankshaft pulley and drives every engine accessory in one loop — the alternator, water pump, A\/C compressor, and power steering pump. On the OM654, the belt runs at 17.8mm wide by 1960mm long and is kept in constant tension by the belt tensioner. As the belt ages, its EPDM compound hardens and cracks, its ribs wear down, and its internal cords stretch — reducing grip on the pulleys and causing slippage under load. A belt that slips on the alternator reduces charging; one that slips on the water pump causes overheating. A belt that breaks ends the drive immediately.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCommon Symptoms of a Failing Serpentine Belt\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSquealing or chirping from the engine bay, especially on startup or when the A\/C is engaged\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eVisible cracking, fraying, glazing, or rib wear on the belt surface\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBattery warning light or low voltage indication from reduced alternator output\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEngine temperature rising due to water pump slippage\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eA\/C performance dropping under load or at idle\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBelt dust or debris collecting near the accessory drive area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhen to Replace\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eReplace at the interval specified in your maintenance schedule or when the belt shows any visible cracking, glazing, or rib wear. Also replace whenever the tensioner or idler pulley is replaced — installing a new belt on worn pulleys will accelerate wear and cause noise to return quickly.
