The engine in the Chrysler Town & Country minivan is sideways. This is the normal orientation for front-wheel driven minivans. This makes replacing the thermostat slightly more complicated than a vehicle with a traditional engine mounted with the crank towards the rear of the vehicle. Because of this, you must take extra steps to prevent losing all of your radiator fluid before you can remove and replace the broken thermostat.

Drain the radiator fluid into a three-gallon container. The radiator drain is located on the lower left of the radiator. To remove the drain, insert a ¼-drive ratchet into the plug and turn it counter clockwise. Close the drain once all of the fluid drains into the pan.
Trace the lower radiator hose to the engine. The hose mounts to the T-Stat intake tube. The thermostat rests inside that tube.
Remove the radiator hose from the T-Stat intake tube with a pair of pliers and then pull the hose off the intake tube.
Remove the two 7/16 nuts that secure the intake tube onto the engine. Be careful, when you remove the intake tube, the thermostat comes out with it.
Pull the old 0-ring out of the bottom of the T-Stat intake tube and place a new one into the groove vacated by the old one.
Discard the thermostat and place the new one into the intake tube. The end of the thermostat with the jiggle vale (long skinny pin) sticks into the T-Stat intake tube.
Place the intake tube against the engine and thread the nuts back onto the studs with your fingers. Tighten the nuts into place with the 7/16 socket.
Slide the hose onto the T-Stat intake tube and secure it with the radiator hose band clamp.
Remove the radiator cap from the top of the radiator and drain the fluid back into the radiator. Close the cap once finished.
