Re: What is the procedure for changing coolant in 2001...
Yes there are bleed screws on the thermostat housing. They look like brake bleeder screws. Open them one at a time while engine is running. open them untill they stream fluid. Leave coolant cap open top coolant as needed.

This vehicle has a double overhead cam engine. The water pump is driven off the timing chain. Unless you have had experience doing internal engine repairs, this is not a DIYer job. There is great risk of doing more damage than good if any step(s) of the repair procedure are not done correctly.
If the thermostat is working, and there is no visible coolant leak or water/coolant in engine oil dipstick, then it could be the electric fan, try running your car and when it starts to overheat check to see if the fan is working. Good Luck.
Before servicing the vehicle, refer to the Precautions section.
Drain the cooling system.
Do not use pliers to open the plastic drain.
Remove or disconnect the following:
It is good practice to turn the crankshaft until the No. 1
cylinder is at Top Dead Center (TDC) of its compression stroke (firing
Negative battery cable
Coolant recovery cap and open the thermostat bleed valve
Water pump mounting bolts, noting the position of the longer bolt
Water pump. Discard the O-ring seal.
Clean the gasket sealing surfaces, being careful not to scratch
the aluminum surfaces.
Fig. Water pump bolt locations, make sure to note the position of
the longer bolt
Install or connect the following:
Rotate the pump and check for freedom of movement.
New O-ring and wet with clean coolant prior to installation. Be
sure to keep the new O-ring free of any oil or grease.
Water pump with a new O-ring. Torque the water pump-to-engine
bolts to 105 inch lbs. (12 Nm).
Fill the cooling system by performing the following procedure:
Close the radiator drain.
Open the thermostat bleed valve. Install a
in. (6mm) clear hose about 48 in. (1.2m) long to the
end of the bleed valve and the other end into a clean container. The
intent is to keep coolant off of the drive belt(s).
Slowly, refill the coolant recovery bottle until a steady stream
of coolant flows out of the thermostat bleed valve. Gently squeeze the
upper radiator hose until all of the air is removed from the system.
Close the bleed valve and continue to fill the coolant recovery
bottle to the proper level. Install the cap on the bottle and remove the
hose from the bleed valve.
Reconnect the negative battery cable. Start the engine and allow
it to reach normal operating temperatures.
Check the cooling system for leaks and correct coolant level.
Be sure that the thermostat bleed valve is closed once the cooling
system has been bled of any trapped air.
You need to go through the proper coolant system bleeding procedure.. There is a bleeder valve in the front center of the intake manifold. You must fill the system, run the car with the heat on until the thermostat opens, top off the coolant and open the bleeder until coolant a steady stream comes out without any air bubbles. Close bleeder, top off coolant, and replace radiator cap. Run car until fan cycles twice on its own.
You probably need to change the thermostat in your vehicle; I found this answer in http://en.allexperts.com/q/Dodge-Repair-809/2000-Dodge-Intrepid-Thermostat.htm THERMOSTAT - 2.7L REMOVAL Disconnect negative cable from remote jumper terminal WARNING: DO NOT REMOVE PRESSURE CAP WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR.
Drain cooling system. Remove accessory drive belt for removal of the generator. Raise vehicle on hoist. Remove generator attaching bolts. Set generator aside for ease of access to thermostat. Remove lower radiator and heater hoses from thermostat housing. Remove thermostat housing bolts Thermostat and Housing - 2.7L Engine Remove thermostat and housing. INSTALLATION Clean gasket sealing surfaces NOTE: Install thermostat with the bleed valve located at the 12 o'clock position.
Install thermostat and gasket into the thermostat housing. Install thermostat and housing to cylinder block. Tighten attaching bolts to 12 N·m (105 in. lbs.) Thermostat and Housing - 2.7L Engine Connect heater and lower radiator hoses. Install hose clamps. Install generator and attaching bolts. Lower vehicle. Install accessory drive belt. Refer to procedure outlined in this section. Refill cooling system. Refer to Cooling System Refilling. Connect negative cable to remote jumper terminal. good luck
