when i changed my belt i noticed that i couldn't get it off with the auto-tensionar. i had to cut it. then me not thinking puts the new one on and relized that the belt is too small. so that day i took my dad;s truck went back to the dodge dealer and explained that you guys screwed up, we laughted. the computer said that they gave me the right belt for a intercooled with a/c. but the non intercooled belt with a/c was longer. so they rushed ordered it next day i got it. no extra cost to me (i get 20% off every thing i buy there) but i couldn't get it on! it was the right size but the auto tensionare wouldn't lossen up enough to let me get the belt on. we ended taking the altinator off. and using a large bar to get it back on.
