On the 1999 Dakota with the 3.9liter, the fan shroud absolutely DOES NOT have to be removed. Very simple job. Simply use a breaker bar with a 15mm socket on the belt tesioner pulley nut. Using the breaker bar push (as though tightening) the pulley nut...the reaction will be that the tensioner removes tension from the pulley and the entire belt can be removed by easily slipping it toward the front of the vehicle...comes right off. The new belt can go back on in exactly the same manner. By the way the belt routing diagram IS CONVIENENTLY LOCATED between the hood latch and the radiator mounting for simple and quick refernce...one person job, I did removal and installation four times in less than 10 minutes. (why four times? The auto parts store was selling replacement belts that were too long and did not allow the belt tensioner to provide suffiecient tension...I had to try four different manufacturers before the tensioner was adequately tight with room to grow as the belt naturally stretches from use.). I found no stringing around the fan is required because of the way the belt is routed (it doglegs around the main engine pulley which is centered below the fanhousing and then the belt runs from there to the left side of the fan housing...avoiding the fan/fanhousing all-together (sure you can try to go past the fan/fan housing if you so desire...but you dont have to...and besides the space between the pulleys and the fan is ample to allow the belt to pass between with minimal interference or a simple rotation of the fan as you attempt this method. One hint that made my installs easy as pie...the last pulley you put it over should not be a bezeled and ridged pulley or you will needlessly make life difficult for yourself...the last pulley should be the water pump pulley which is a smooth bore and non-ridged pulley (makes you wonder how the belt even stays on it!)...making it easy as pie to slip it right over...as your last act of defiance to that mean old serpentine belt!

You didn't specify what size engine you had so I've attached 3 diagrams.
1st is for 4.9L
2nd is 5.0 & 5.8L
3rd is 5.0 & 5.8L late model
If you require the 7.3 or 7.5 please post back.

Here's a link to a series of videos that will explain how to change the serpentine belt.
Here is a diagram of the belt routing which will help you put the belt back on correctly...

There is a distinct possibilty there is engine damage caused when the belt broke. It is best not to turn the engine at all once this happens. Sometimes you can be lucky and there be no damage. Let's hope that's so in your case. These belts are supposed to be replaced every 100,000km.
