Serpentine Belt - Variations

Variations

On some engine designs, the "back" (smooth side) of the belt may drive some accessories. This is typically limited to components requiring less torque or where a large angle of lap is present. Such accessories will counter-rotate vs. the "normal" pulleys. Some vehicles use two serpentine belts for their system, such as the manual transaxle equipped Ford Taurus SHO, 1995–1999 DOHC Nissan Maxima, vehicles using the supercharged GM 3800 engine, and many BMWs.

Famous quotes containing the word variations:

    I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.
    Edward T. Hall (b. 1914)
