What is the difference between a V Belt and a Serpentine Belt?
V Belt is thin and V in shape, and is normally used to power a single component in a system of pulleys. Serpentine Belt is wider, and is used to drive multiple components in automotive engine, it loops continuous over several pulleys. In addition, V Belts are normally found in older automotives.
there is no serpentine belt on an '86. there is a v-belt and a timing belt. the v-belt is tightened by moving the alternator. the timing belt is tightened by rotating the inner core of the tensioner. the inner core is eccentricly mounted, i.e. if you rotate it, the tensioner moves. there is a serpentine belt alond with two independent belts.
No, the serpentine belt is used to drive more than one thing and tension is automatically adjust by way of a spring loaded idler pulley. Normally it will drive the alternator, power steering pump, & A/C compressor. A drive belt normally drives only one thing and tension is manually adjusted. A serpentine belt is wider that a drive belt and is not a V-Belt like a drive belt.
There is no serpentine belt on the 2.7 it' s chain driven. Whoever says there is no serpentine belt on a 2007 Toyota tacoma and that it is chain driven is absolutely morbidly stupid. They must be thinking of the timing chain but every vehicle has either serpentine belt or v-belts to run the alternator or water pump or power steering pump. Don't answer the question if you don't know what the hell you are…
