FAQ:

Q: Where is the serpentine belt located on a 2003 Chevy Silverado?

A: The serpentine belt on a 2003 Chevrolet Silverado runs the entire pulley system on the front part of the engine. Older model Chevrolet Silverado trucks had three different belts to run each pulley.

Q: Where is the serpentine belt on a Toyota Camry?

A: Pop the hood and locate the serpentine belt routing diagram located on the top of the fan shroud. If the diagram is not there, tale a notepad and draw out the exact belt routing over the pulleys before you remove the old belt. Locate the belt tensioner, which is at the top left above the air conditioner compressor.

Q: How do you remove the serpentine belt from the pulleys?

A: The serpentine belt has tension applied to it by a spring-loaded tensioner that is attached to the engine itself. In order to remove the belt from the pulleys, you will need to release this tension, which will slacken the belt and allow you to remove it from the rest of the pulleys.

Q: How often should I replace the serpentine belt on my car?

A: It is recommended that the belt be checked every 6,000 miles or six months, and replaced when necessary. Figure 1. Shredded serpentine belt. Before beginning, take a good look at the routing of the serpentine belt.
