My F-150 '04 has a 5.4L Triton. I believe this is a pretty accurate diagram of the serpentine belt. I want to have a better understanding of what's under then hood. I'm pretty familiar with the basics of an internal combustion engine, but not as much with some of the more automotive parts.
Can someone give a brief explanation of the "Idler Pulleys", and why do I have 3 of them? Also, what is the "A/C Clutch"? Lastly, why does it say "Generator", when I know I have an alternator?
