It is a spring-loaded mechanical component designed to maintain the precise amount of tension on the drive belt, ensuring that the alternator, water pump, and air conditioning compressor operate without slipping.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe N47 tensioner features an internal damping mechanism to absorb the vibrations inherent in a high-compression diesel engine. Over time, the internal spring can weaken, or the pulley bearing can begin to seize. Common symptoms of a failing tensioner include a constant \"squealing\" or \"chirping\" noise from the front of the engine, visible belt oscillation (fluttering) while the engine is idling, or \"glazing\" on the edges of the belt. If the tensioner fails completely, the belt can slip off or snap, leading to an immediate loss of power steering and engine cooling. Replacing the tensioner is a standard procedure when fitting a new drive belt to ensure the longevity of the entire accessory drive system.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eVehicle Compatibility:\u003c\/b\u003e This tensioner is designed for the \u003cb data-path-to-node=\"3\" data-index-in-node=\"58\"\u003eN47\u003c\/b\u003e engine family:\u003c\/p\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003e3 Series (F30 \/ F31):\u003c\/b\u003e 2007–2015 (316d, 318d, 320d, 325d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003e5 Series (F10 \/ F11):\u003c\/b\u003e 2007–2017 (520d, 525d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003e1 \u0026amp; 2 Series (F20 \/ F22):\u003c\/b\u003e 2007–2015 (116d, 118d, 120d, 123d, 125d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003eX3 (F25):\u003c\/b\u003e 2007–2014 (xDrive18d, xDrive20d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,5,0\"\u003e\u003cb data-path-to-node=\"4,5,0\" data-index-in-node=\"0\"\u003eX5 (F15):\u003c\/b\u003e 2013–2015 (sDrive25d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,6,0\"\u003e\u003cb data-path-to-node=\"4,6,0\" data-index-in-node=\"0\"\u003e4 Series (F32 \/ F36):\u003c\/b\u003e 2013–2015 (418d, 420d, 425d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eType:\u003c\/b\u003e Spring-Loaded Mechanical Tensioner\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eMaterial:\u003c\/b\u003e Die-Cast Aluminium Arm with Steel\/Composite Pulley\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MYTY Auto Parts","offers":[{"title":"Default Title","offer_id":48057587171567,"sku":"11287800333","price":1450.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/7183\/5631\/files\/2012-F30-320d-N47-Belt-Tensioner.png?v=1773875366","url":"https:\/\/myty.co.za\/products\/belt-tensioner-bmw-1-2-3-4-5-series-x1-x3-x5-n47-n47n-n47s","provider":"MYTY Auto Parts","version":"1.0","type":"link"}
