On the 3.3L V6 motor the belt tensioner bolt needs to be loosened by turning it counter clockwise, you don't need to take it all the way out just loosen it up a bit. You will need two people to get the belt on. One person can get under the car and using a large 19mm box wrench push up on the front of the tensioner. You will notice that the belt goes slack when you do this. I have found it best to put the belt on everything except for the alternator. Then by putting slack on the belt have your helper move the belt onto the alternator. Just watch your fingers cause once you get that belt on it is tight.
its on the left side. its the easyest pully to see.
Since There is no tensioner pulley you have to loosen your alternator.
The pulley bellow the alternator is the tensioner. Rotate it with a 15mm to loosen belt.
Yes, on a 3.3 or 3.8 the serpentine belt pulley does come off the tensioner arm but the bolt is left thread not right handed.
The 1998 Dodge Dakota tensioner pulley will be the top pulley on the left-hand side of the engine. The tensioner pulley will be able to slide back and forth.
The tension spring is broken, and the entire assembly must be replaced.
You have to unscrew the tensioner bolt and remove the serpentine belt first, then change the pulley and replace the belt.You have to unscrew the tensioner bolt and remove the serpentine belt first, then change the pulley and replace the belt.
It should be a 16mm on the front, to release and put tension on. To remove the tensioner pulley completely, I believe the nut that holds it on from behind is a 15mm.
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. That's It. Bill 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.
the idler pulley.
You unbolt the old one (one bolt) then fit new. Now refit the belt.
You cannot adjust the belt tension on a 2000 dodge grand caravan. This vehicle is equipped with an automatic tensioner. If tensioner is frozen or will not hold the belt tight, it must be replaced.
