How to Service a Belt Tensioner on a 5.9L Diesel Engine on 2003 Dodge Ram 2500?

Before servicing the belt tensioner on a 5.9L diesel, first get rid of the accessory drive belt. Coming next, pull out the bolt that holds the tensioner into the mounting surface and remove the tensioner as a whole, since the automatic tensioner must not be separated as the spring has a high pressure. Building the tensioner system, place it onto the mounting bracket so the dowel at the back matches the hole and tighten the bolt down to 43 Nm (32 ft. lbs.). At the last step, bring the drive belt back into place.
