Dayco® Top Cog® Belt is the workhorse of the heavy-duty industry. The cogs in the top of the belt deliver increased flexibility around small pulleys, and the increased surface area results in a cooler running belt. Polyester cord provides maximum power transfer and tension holding capability for the life of the belt. The laminated construction helps absorb greater shock loads associated with diesel engines. These Dayco® Top Cog® advantages translate into less downtime, lower maintenance costs, and increased dependability. The Dayco® Top Cog® Belt meets or exceeds SAE J636 and J637 specifications.

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.
