Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Drive Belt Routing: Description
The single ("serpentine" or "V" ribbed) drive belt system has been adopted by manufacturer's as a replacement for multiple "V" belt systems previously offered. The serpentine belt requires a belt tensioner similar to those used to control timing belt tension.
Use of a tensioner allows engine accessories to be mounted rigidly on the engine. The single belt drive system has a predicted life of 100,000 miles before replacement is required.
The belt tensioner has a wide functional range and is capable of maintaining tension during the expected life of the belt. Tensioner cannot compensate for extreme belt lengths. Poor tension control and possible tensioner damage can result from excessive belt length.
