Answer 1: 4 cylinder The A/C belt and the Alternator belt are the same on a 97 Caravan. Just losen the alternator bolt and it should be able to come of easy Answer 2: My 2000 Dodge Caravan 3.0 has two belts; one serpentine for the alternator and steering pump and a typical v-belt for the a/c. The serpentine is the wider belt of course and it snakes around the alternator pulley, a spring loaded tension idler, a fixed idler, a crankshaft pulley and a Power Steering pump. The tension idler is located nearest to the alternator and should appear as a tension idler on the serpentine belt path decal in the engine compartment or other belt diagrams that can be had on line or in a repair manual . The second idler is fixed and cannot be adjusted. The tension idler can be pulled down in an arc toward the front of the car with a 15mm wrench on the idler shaft bolt by applying pressure as if you were tightening the idler's shaft bolt until the idler's spring tension is overcome and idler will move in a forward arc thereby reducing the pressure on the serpentine belt so that the belt can be removed and/or installed. The tension idler does not require the loosening of any locking bolt as is the case with the a/c idler in the following paragraph. It might be easier to use an extension handle on the wrench in order to move the tension idler. It might also be easier to have a second person to move the tension idler,but in any case, make sure the socket or box wrench that you will be using is securely attached to the bolt. DO NOT USE A PRY BAR AS IT CAN EASILY SLIP! Turning the idler shaft bolt counterclockwise will simply be removing the idler. When the idler shaft bolt is released and is applying tension to the serpentine belt, ascertain that the belt has fit properly on each of the grooved pulleys.

The a/c belt is a V-belt that connects the crankshaft and a/c compressor pulleys and the V-belt's tension is maintained by a manually adjustable idler pulley. Unlike the serpentine belt the V-belt doesn't have a spring loaded tension idler. The idler pulley creates belt tension by the turning of an adjustment screw which moves an idler pulley shaft bracket away from the tangential line of the a/c V-belt . Before the bracket will move in response of the turning of the adjustment screw however, you must loosen the idler pulley shaft screw to allow the bracket to slide. Screw the adjustment bolt counterclockwise to allow the idler pulley to free all tension and then some to facilitate the V-belt removal and/or installation.

Once tension is removed from the belts, they can be removed. To get the serpentine belt off, the V-belt has to be removed, unless you are Houdini. The greatest physical exertion should be the movement of the tension idler and with an extension, a child could make the movement. To install the serpentine belt simply place it properly on the pulleys and idlers and release the tension idler.

To install the V-belt, reverse the above V-belt removal steps and tighten the idler pulley bracket adjustment bolt until the belt is tight but do not over tighten the belt and DON'T FORGET TO TIGHTEN THE IDLER PULLEY SHAFT SCREW when you are satisfied with the tension! Check the belt area for tools and for improper conditions before starting the engine.

Viel Glück Good luck. Answer 3: If you have a 3.3 or 3.8 liter you need to rotate the belt tensioner, which is below the alternator, with a 15mm wrench. You can now slide belt off.
