A car engine is an intricately built mechanism. To aid the moving parts within the compartment, a tensioner on a belt provides assurance that a main driving pulley does not become loose.
A tensioner works along with the serpentine belt, which is the pulley that drives the engine's accessory components, such as the air conditioning compressor or water pump. To prevent damage or failure, a tensioner makes sure that the serpentine belt is tightly placed along its normal pulley route.
The tensioner employs a spring that places pressure along the serpentine belt for an intricate hold. Additionally, the tensioner allows some movement based on the typical vibrations associated with the accessories so that the serpentine belt is not stretched over time.
When a new serpentine belt is needed, make sure to inspect the tensioner at the same time. If it is worn, it should be replaced so that the new serpentine belt has proper traction along its path.
