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!

follow the upper radiator hose to the engine, drain about 1/2 gallon of coolant and then pull upper hose off at the engine, look inside the metal large nipple, that is the thermostat.

Below are the steps needed to remove the catalytic converters. You may be able to first remove the band clamp from between the converter and the exhaust manifold, then loosen the rest of the system and to get enough clearance to slide the converter towards the front of the vehicle but you will need to first remove the clamp that holds the converter to the rest of the exhaust. Hope this helps
Both Catalytic Convertors
First you need to raise the vehicle.
Next, you need to pry the insulators from the support brackets and support the muffler and tailpipe with jackstands.
Then, loosen the the catalytic converter down pipe-to-front resonator clamps and separate the front resonator from the converter down-pipes. Carefully lay the free laying exhaust on the ground.
Right Catalytic Converter
Then, remove the down-pipe-to-transaxle bracket nut, loosen the clamp and separate the extension pipe from the converter.
Next lower the vehicle and remove the air filter and intake ducts. Disconnect the wiring harness for the O2 sensor and the remove the sensor.
Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment. You may need to replace these clamps after removal because you need to pry it apart and they will leak when you reinstall.
Left Catalytic Converter
Now disconnect the wiring harness for the O2 sensor and the remove the sensor.
Next remove the down-pipe-to-transaxle bracket nut
Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment.
