All the Chrysler minivans from 1996-2000 with V6 engines have a pulley alignment flaw that causes the belt to fall off, usually in the rain. The only way to fix it for good is to buy the repair kit they make specially for that problem. It includes a new tensioner, new idler, and a double sided grooved belt that prevents it from falling off. It can be purchased online through Gates or ordered from Advance Auto Parts for about $120.

Location of belt tensioner on dodge Dakota truck?

Facing the engine the tensioner will be on left side of engine. There is an idler pulley that looks like the tensioner. The idler will have a smooth surface but the tensioner will have grooves on the pulley & should below the idler. If the tensioner is making noise etc it is prob just the tensioner pulley (grooved one) & you can get just the pulley. Big savings.

How do you change the serpentine belt on a Dodge Caravan?

What you need is a ratchet 15mm socket. Losen the idler then slide off the serpentine belt off. There should be a diagram for routing the belt if not draw a diagram before removing it. Replace the serpentine belt crank it 2 or 3 times but don't start the engine. The 4th time start the engine this time the as the engine is idling eyeball the belt agaisnt the tensioner idler and crank pulley make sure the serpentine is algined. A Note: Make sure that you have identified the tensioner pulley as apposed to the idler pulley. With the 15mm socket on the tensioner pulley's bolt, rotate it clockwise and this will release the tension on the belt, or in the case of installing a new serpentine belt, allow you to get it where it belongs. This is the case on my 1997 Dodge Caravan, and probably other year makes. Best of luck- Bryan 1993 Dodge Grand Caravan: Rotating the tensioner pulley's bolt clockwise was the way to replace my belt. By the way, the tensioner pulley in my van was one of the smaller ones in the middle of the whole system, attached to a silver arm coming off the tensioner. Good luck...
