What is a tension pulley?

A tension pulley, also known as a belt tensioner, is a mechanical device used to maintain the tension of the serpentine belt in an engine. It is typically equipped with a pulley wheel and an adjustable arm that exerts force on the belt to keep it properly tensioned. The tension pulley ensures the belt remains in contact with various engine components, such as the alternator, power steering pump, and air conditioning compressor, to ensure their proper functioning.
