Hi, Follow the top rad hose and at the end of that is the thermostat. Undo the two bolts and there it is.
But first you will have to drain some fluid out to make it easier to access. Good luck.

Find the location where the upper radiator hose connects to the intake manifold of the engine by tracing it from the radiator to thermostat intake housing bolted to the intake.

2 Remove the radiator hose from the thermostat intake housing by loosening the band clamp that secures it into place. With the clamp loosened, pull the hose off the housing.

3 Remove the two bolts that secure the housing to the intake manifold and then lift the housing off the intake.

4 Lift the thermostat out of the intake manifold and place the new thermostat into the hole. The end of the thermostat with the pin protruding from it sticks out of the intake manifold.

5 Lift the thermostat intake housing gasket off the intake manifold and place the new one onto the intake manifold.

6 Place the thermostat intake housing onto the intake manifold and bolt it into place. Reconnect the hose using the band clamp.

Six-Cylinder Engines

1 Drive the Dodge onto a set of front-end ramps and secure the parking break. Allow adequate time for the radiator fluid to cool down. Thirty minutes is usually adequate.

2 Loosen the petcock on the lower right hand side of the radiator and drain all of the radiator fluid into a drain pan. Close the petcock once drained.

3 Trace the lower radiator hose to the location where the hose connects to the engine block. The metal housing the hose connects to is the lower thermostat outlet. Remove the hose from the outlet by loosening the band clamp and then by pulling the hose off the outlet. Be careful--some fluid will drain from the hose.

4 Remove the two bolts that secure the thermostat outlet to the engine block and pull the thermostat outlet off the block.

5 Discard the O-ring inside the bottom edge of the thermostat outlet and place a new one into the outlet.

6 Pull the thermostat out of the engine block and replace it with a new one. The end with the pin protruding from it sticks out of the engine block.

7 Place the thermostat outlet onto the engine block and secure it into place. Reattach the lower radiator hose with the band clamp.

8 Open the radiator filler cap located on top of the radiator and fill the radiator with the fluid previously drained from the system.

please dont forget to give good rateing thank you

Check this procedure to REMOVAL & INSTALLATION
(1.8L and 1.9L Engines)

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

1. Disconnect the negative battery cable.
2. Place fender covers on the aprons.
3. Raise and safely support the vehicle. Drain the cooling system.
4. Remove the right and left-hand front splash shields.

10. Start the car and check for coolant leaks.

Hope helps (remember to rate this asnwer).

Start by removing the shroud over the radiator area. There should be little plastic screws in it holding it on. Then drain the coolant from the old radiator. there should be a drain on the lower passenger side of the radiator facing the rear. looks like a white nut, turn that until fluid runs out. Make sure you have something available to catch the coolant. I used a small rubber hose attached to the end of drain to direct it to container. After all fluid has drained, disconnect the overflow hose running to the plastic bottle on right of radiator. Remove the 3 bolts holding the bottle in place, and remove. You will not have to remove fan and shroud from vehicle if you just remove the four bolts holding the blade itself to the pulley you can then slide them back far enough away from radiator to get it out. That will make things much easier. there are two other hoses that attach to the radiator 1 on upper passanger side and 1 on lower driver side, remove those. Then remove the two transmission cooling lines from the radiator and plug the ends to prevent dirt getting in. Once all hoses and lines are detached from radiator remove the two mounting bolts at top of the radiator where it attaches. Those are the only bolts holding it in. it rest inside grooves at bottom so you just pull up the radiator and you have it removed. Installation is the opposite of removal. Try to get your plastic (degas) bottle as clean as you can if your reusing . If radiator will not drain through plug for whatever reason, removing the lower driver side hose will drain very quickly but be ready for a rush of coolant. I hope this helps you out.
