What is a Serpentine Belt?

A serpentine belt is a multi-ribbed belt that is essential for powering your car’s accessories, such as the alternator, power steering pump and air conditioning compressor. It was introduced in 1978 by the Ford Motor Company, and it has since become standard equipment on most engines. The serpentine belt is driven by a grooved pulley on the engine crankshaft that matches the grooves of the serpentine belt. The number of ribs on the belt makes it more resistant to slipping off or becoming stretched out of shape over time.

Typically, manufacturers use one or two serpentine belts in their engines, depending upon whether power–steering or air–conditioning pumps are included. The belts are made from synthetic rubber with reinforced fibers embedded into them and are measured in inches by width (1/2 inch, 5/8 inch). Selecting one with too small a width could cause your engine to be underpowered while using one with too large of a width can strain your engine components. To ensure you get the correct size, consult an automotive service professional when selecting a new belt for your vehicle.

Benefits of a Serpentine Belt

The serpentine belt, also known as the drive belt or poly V-belt, has become a mainstay of contemporary engine design. It is made up of several ribbons of different lengths bonded together to form a single belt. Although the use of serpentine belts has several advantages over traditional power transmission belts, its greatest benefit is that it reduces the complexity and cost associated with routing multiple accessory drive belts around pulleys and an engine’s accessories.

Moreover, because the single serpentine belt passes only around a series of pulleys mounted on each accessory, it generally operates within one foot in length. This significantly reduces underhood space requirements and installs quickly with minimal adjustments required on installation. Furthermore, it offers less tensioning alterations than are necessary with many existing drive belt designs. Finally, serpentine belts provide improved transmission efficiency by decreasing friction and bypassing worn-out grooves in pulleys or excessive slack existing in power transmission belts caused by ill-fitting components.

There are a few key factors to consider when you’re in the market for a serpentine belt for your Duramax engine. As you shop, pay attention to the size of your belt and make sure it’s compatible with your engine model. You’ll also want a durable belt that can withstand frequent use over time and one that’s crafted from quality materials for maximum performance. Below, we explain the main points to consider when choosing a serpentine belt for your Duramax engine.

Size: Make sure you purchase a Duramax serpentine belt with the exact dimensions needed for your make/model/year vehicle. The smaller tensioner pulley has a smaller circumference than the larger one, so note which size belts are required before buying what you think is going to be just the right fit.

Durability: Look for belts constructed from robust materials like Kevlar or Nylon 6,6 reinforced rubber cord that can withstand high temperatures while resisting cracking and deterioration caused by regular contact with moving metal parts and chemicals present in some coolants and oils. Additionally, look for belts rated as “High Mileage Belts,” which have been specially designed with extra reinforcement constructions perfect for vehicles running 75k-125k miles or more during its lifetime.

Quality: Low-grade materials can lead to broken belts or ones that slip off unexpectedly on sharp turns or speed changes — leading to bigger problems if left unchecked. Be sure to purchase your Duramax serpentine belt from a reputable manufacturer known for producing quality components built specifically for an engine like yours.
