The auxiliary drive tensioner is a high-precision element<\/strong> designed, as its name suggests, to optimize the tension<\/strong> of the accessory belt<\/a> and also prevent future failures<\/strong> in the other components such as the alternator<\/a> or the pump<\/a>.<\/span><\/p>\n

In today’s article, we will learn how it works, the different types that we find on the market and the importance of this key element for <\/span>the accessory drive system<\/span><\/a>.<\/span><\/p>\n

How does a belt tensioner work?<\/strong><\/h2>\n

 <\/p>\n

As we have seen in previous articles, the auxiliary drive belt transmits rotational energy<\/strong> from the engine crankshaft to all engine accessories.<\/span><\/p>\n

What happens is that, during the operation of the auxiliary drive system and as our vehicle’s engine speeds up and slows down, <\/span>the belt can stretch or even lose some tension<\/b>, hence the importance of the tensioner pulley<\/a> within this system.<\/span><\/p>\n

The aux drive tensioner or serpentine belt tensioner is, therefore, an element responsible for exerting a regulated amount of pressure\/tension on the belt and thanks to this the belt can rotate all those pulleys as needed.<\/span><\/p>\n

Potentially, its main function is to guarantee that the auxiliary belt has the optimum tension, although among its basic functions we also find:<\/span><\/p>\n
