  Q: How to service the drive belt tensioner on Dodge Ram 3500 Van?

  A:

  You must first remove the accessory drive belt to work on the tensioner. After unplugging the wiring and secondary cable from the ignition coil, remove the coil from the bracket with two bolts so that the mounting bracket remains in place on the cylinder head. Then, come apart the assembly by unfastening the nut holding the tensioner to the mounting bracket and then take off the pulley bolt. Begin with attaching the pulley, putting the pulley bolt through it and tightening the pulley to a torque of 61 Nm (45 ft. lbs). Put the tensioner assembly onto the bracket and place its indexing tab into the bracket's index slot; once aligned, tighten the nut securely to 67 Nm (50 ft. lbs.) torque. Attach all wiring back to the ignition coil, making sure the coil mounting bolts are torqued enough to not harm the coil case. Attach the coil by putting it into the bracket and using a torque wrench to tighten it to either 11 Nm (100 in. lbs.) or 5 Nm (50 in. lbs.) if the bracket is threaded for bolts. After the replacement, put the drive belt back and make sure to line up the belt indexing marks.
