Why does ford engine use serpentine belt?
I'm so impressed by the serpentine belt configuration of the
V6 vulcan 3.0 12V engine in my Sable GS. In this configuration,
the crankcase shaft outputs power from engine to drive all
the rotating components.
Since this belt has to route so many units. I just worry if
this is the culprit that this engine has a poor gas mileage
and power output compared to its Toyota, Honda counterparts.
Indeed I really have a negative opinion on the belt guide,
and belt tensioner location. These two things do nothing
but dissipate engine power. Although they were initially designed
to prevent slipperiness when friction force was generated between
pulleys and belt to drive units like water pump, generator, etc.,
I just feel they are not placed in the right locations to do this job.
I hope Ford can do something to correct this drawback in
their engine design of later models.
