here is a link to the tensioner pulley (pulley diagram #5 pulley)
. Looking from the passenger side, it is the middle pulley from the right side. It is a 13mm wrench or socket, and it is turned toward the rear of the motor to loosen. You will probably need a second person to align the belt from the top of the motor while you loosen it from beneath. There is not much room for a socket, so i found it easier to use a small breaker bar or long handled wrench. Good luck
You can change the serpentine belt by loosening the tensioner pulley. When the tensioner pulley is loose and the serpentine belt will become loose. Put the new serpentine belt on and tighten the tensioner pulley.
The Serpentine Belt needs to be tightend with the tensioner pulley (Idler Pulley)
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.
The serpentine belt tensioner is held in place by one bolt. The retaining bolt goes through the middle of the serpentine belt tensioner pulley.
The pulley bellow the alternator is the tensioner. Rotate it with a 15mm to loosen belt.
The correct belt tension will be maintained by the belt tensioner. The tension is not adjustable on this car.
Put the belt tensioner tool on the tensioner pulley, and push away from you. Then you can slide the belt off. You either need to cut it or unbolt the engine from its mount and slip it out.
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.
where can i get a diagram for a serpentine tensioner belt for a 1998 Oldsmobile bravada
short answer: just above the ac pulley long answer:http://www.rldassociates.com/zx2/howto/belt.htm
I have used a socket with a ratchet handle. The ratchet will allow you to get more travel to move the pulley and get the belt off.
As viewing the motor from the front of the car, the belt tensioner is located on the left side of the engine. On what is essentially the front of the motor, the belt tensioner is located just below the idler pulley.
