( Manufacturer Part Number: 8658225 ), ( Type: Timing Belt Tensioner )
The Volvo 8658225 engine timing belt tensioner is an essential component of the Volvo 850 engine series, specifically the 2.4-liter five-cylinder engines. This tensioner plays a crucial role in maintaining the proper position and tension of the timing belt, ensuring the synchronization of the engine's valves and camshafts.
The Volvo 8658225 engine timing belt tensioner is a hydraulic unit, meaning it uses engine oil pressure to apply the required tension to the timing belt. The tensioner housing is made of durable cast aluminum, providing excellent heat dissipation and resistance to engine bay conditions. The tensioner pulley is machined to precise specifications, ensuring a perfect fit and optimal belt tension.
The 8658225 timing belt tensioner features a tension roller with a self-adjusting mechanism, which automatically compensates for belt wear and stretching over time. This self-adjusting feature helps maintain consistent belt tension, ensuring reliable engine performance and prolonging the life of the timing belt and other related components.
The timing belt tensioner also includes a pulley with a built-in water pump, which is driven by the timing belt. The water pump is responsible for circulating coolant through the engine, keeping it at an optimal operating temperature. This integrated design simplifies installation and maintenance, as both the tensioner and water pump can be replaced as a single unit.
The Volvo 8658225 engine timing belt tensioner is designed to meet or exceed OEM specifications and is manufactured to ensure a perfect fit and reliable performance. It is recommended that the timing belt and related components, including the tensioner, be replaced at the manufacturer-recommended intervals to ensure the longevity and optimal performance of your Volvo 850 engine.
