How do you release the belt tension on a 2003 dodge grand caravan?

Answer 1

If you're talking about the serpentine belt, there is a belt tensioner between the water pump pulley and the anti-vibration pulley, both of which are visible when you remove the right front tire and the plastic cover. There is also a diagram of the location of these items in front of the radiator under the hood. To remove the tension on the serpentine belt, take a pry bar and pry the pulley end of the belt tensioner down using the frame as the pry point. The spring on the tensioner is pretty stiff, so it will take some effort.
