Am I going crazy or is the a/c belt seperate from the serpentine belt? While doing my oil change today I found the lovely shreaded belt (could explain my new check engine light and lack of anoying thud when the defrost is on). How hard is this belt to change? anyone have a daigram for it? Doesnt look to hard but im gettin very worn out on this truck at the moment and just looking for confirmation that I'm not seeing things:doh: - thanks.
