  Q: How to Maintain and Repair a Belt Tensioner on a 2.7L Engine on Dodge Magnum?

  A:

  First, make certain that the indexing tang of the tensioner is about 6-8mmisnide the indexing stop on the tensioner casing when you install a new belt that has only been used for up to 15 minutes. If the specification isn't correct, it may be because the belt was installed improperly, the bearings in the compressor, Power Steering Pump, Water Pump, idler pulley or generator are worn, the belt was set in the wrong place on a pulley, one or more accessories are loose, their alignment is off or the belt was improperly routed. You should replace your used belt if the tensioner arrow is showing the minimum tension, because the tensioner will not move beyond this point. First, unplug the accessory belt and do not open the automatic tensioner because compressing it can be dangerous and the tensioner comes apart as an assembly except the pulley on it. After that, separate the tensioner assembly bolt, then pull the tensioner assembly out of the mounting bracket.

  Q: How to Properly Install a Belt on a Belt Tensioner on Dodge Magnum?

  A:

  A tang is set on the housing of the belt tensioner and matches up with an indexing stop on its backside. Basically, the new belt tang should be positioned almost touching the indexing stop, approximately 6 8mm (0.24 - 0.32 inches) apart. When this measurement is not right, check whether there's a wrong belt in the car or worn bearings on the A/C compressor, Power Steering Pump, Water Pump, idler pulley or generator. A used belt must be changed when the tensioner indexing arrow is at its lowest tension position, as that's when the tensioner carriage cannot move any further. Remove the accessory Drive Belt first and don't dismantle the automatic tensioner because it has high spring pressure; it is repaired only by replacing the pulley. Following this, take out the tensioner assembly bolt and get rid of the assembly from the bracket. First, add the tensioner bolt to the tensioner and tighten it up to 34 Nm (40 ft. lbs); after that install the accessory drive belt and make sure the belt indexing marks are lined up properly.
