What is the purpose and inspection process for a serpentine drive belt on GMC Sierra?

The serpentine belt is found in front of the engine and is essential for driving the engine and its components. In view of what it does and how it is made, this belt should be checked regularly. The serpentine belt drives the alternator, power steering pump, water pump and air conditioning compressor. With the engine not running, lift the hood and feel along the belt for any cracks or separations in the belts layers using your fingers (and a flashlight if needed). Also check for fraying and glazing that gives the belt a glossy appearance. You may have to twist the belt in order to inspect both sides of it. Inspect its lower side as well. They should all look similar, with none of them having an uneven surface. The tensioner system uses a spring-loaded tensioner assembly and cannot be adjusted manually. Replace this part when you can see that mark on moving part of the tensioner has moved out of range on stationary part of tensioner. To fit a new one turn the tensioner to allow release of a belt's pressure . This will entail removing it from such devices as a tension and auxiliary components, thereafter allowing slow release of a tensioner until it gets slack enough for removal of the belt. Route new belt over various pulleys again rotateingtensionerto permit installation thenreleasebelt's tensioners To replace faulty pulley/bearing, binding or lack of springiness on a tensioner remove mounting bolts. Follow reverse process during installation.

GMC Sierra Drive Belt

The GMC Sierra Drive Belt is the component that allows the engine to spin parts such as the alternator, power steering pump, and A/C compressor, which powers all of the Sierra systems without the use of electric motors. The Drive Belt wraps around various pulleys and loops from each component back to the crankshaft pulley. Thus, a single continuous strip transmits motion, allowing rotation to energize components with efficiencies of up to 98 percent. In contemporary trucks, the use of a serpentine type of Drive Belt is observed. This is a multi-groove belt having a tighter grip and lesser slip. It runs through a complex route that was earlier applied only by several V-belts. These V-belts were thicker in size, ran into separate grooves, and lost grip easily. Earlier versions of the pickup applied those V-belts for shorter paths, but the switch delivered smoother operation, lighter weight, and simpler tension adjustment that drivers appreciate in every GMC ride. Constructed of flexible synthetic rubber to tolerate temperatures from -5 to 85 degrees Celsius, the Drive Belt is designed to last approximately 100,000 miles. However, if you see any cracks or frays, replace the Drive Belt immediately. Otherwise, certain components on your GMC Sierra may be disabled and the engine may overheat.

Each OEM GMC Sierra Drive Belt we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: What is the purpose and inspection process for a serpentine drive belt on GMC Sierra?
A:
The serpentine belt is found in front of the engine and is essential for driving the engine and its components. In view of what it does and how it is made, this belt should be checked regularly. The serpentine belt drives the alternator, power steering pump, water pump and air conditioning compressor. With the engine not running, lift the hood and feel along the belt for any cracks or separations in the belts layers using your fingers (and a flashlight if needed). Also check for fraying and glazing that gives the belt a glossy appearance. You may have to twist the belt in order to inspect both sides of it. Inspect its lower side as well. They should all look similar, with none of them having an uneven surface. The tensioner system uses a spring-loaded tensioner assembly and cannot be adjusted manually. Replace this part when you can see that mark on moving part of the tensioner has moved out of range on stationary part of tensioner. To fit a new one turn the tensioner to allow release of a belt's pressure . This will entail removing it from such devices as a tension and auxiliary components, thereafter allowing slow release of a tensioner until it gets slack enough for removal of the belt. Route new belt over various pulleys again rotateingtensionerto permit installation thenreleasebelt's tensioners To replace faulty pulley/bearing, binding or lack of springiness on a tensioner remove mounting bolts. Follow reverse process during installation.
