Is a pulley and tensioner the same thing?
Is a pulley and tensioner the same thing?
The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt. However, if bearings fail, tensioner and idler pulleys both require replacement.
What happens when tensioner goes bad?
Driving with a bad belt tensioner is unsafe since the tensioner is meant to guarantee ample tension that powers accessories. Wear on the belt tensioner will eventually cause the belt to slip, generate loud noise, and also create an unsafe level of heat along the accessory pulleys.
What sound does a bad tensioner pulley make?
When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise.
How long does it take to replace a belt tensioner?
It should only take about an hour of work for the replacement, but sometimes it can be more, which can drive up the labor costs, and that varies from one car to the next.

What noise does a bad pulley make?
