This Dayco® No Slack® Heavy Duty Idler/Tensioner Pulley is designed to replace idler and tensioner pulleys for serpentine drives in heavy duty diesel engine applications. This pulley is manufactured from a high strength powdered metal material to afford wear resistance under harsh environments; and, it features double pressed-in bearings to provide long bearing life despite the shock loads experienced in diesel engine applications. The performance demands of original equipment manufacturers of over-the-road trucking and off-road equipment require a "built for punishment" heavy duty construction, that is why they specify Dayco® No Slack® Heavy Duty pulleys.

Customer Questions
Can a serpentine belt cause smoke?
Yes, a serpentine belt can cause smoke. A serpentine belt is an essential component of a vehicle's engine system. It drives various accessories such as the alternator, power steering pump, water pump, and air conditioning compressor. If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.
Why is my serpentine belt squealing?
The serpentine belt can squeal due to various reasons, including tension issues, worn-out belt, or a problem with the belt's pulleys.
Is my serpentine belt too tight?
If your serpentine belt is causing issues like excessive noise or accelerated wear on the pulleys, it may indicate that the belt is too tight.
Why did my serpentine belt come off?
Serpentine belts can come off due to factors such as belt wear, improper tension, misaligned pulleys, or a faulty tensioner.
