Chances are, you didn't even know that your INFINITI Q50 sedan featured belt tensioners. If you did, you probably don't spend much time thinking about them. What they do is simple in nature. They're responsible for keeping your vehicle's belts tightened to the proper tension level, allowing them to operate without fear of becoming too slack or overly tight.

Types of Belt Tensioners

While there are three main types of belt tensioners, they all work in the same general way. They deliver the power that your alternator and auxiliary pumps need to keep parts moving. The most common type of belt tensioner is a spring-loaded version, while hydraulic tensioner assemblies are more often seen in models with larger engines. Lastly, a manual belt tensioner is the oldest type, and typically reserved for vehicles equipped with timing belts.

How to Spot A Faulty Belt Tensioner

  • Squealing noises coming from your belts
  • Too much play in the tensioner arm
