Pulling the ecm fuse 2004 Chevy venture - 2004 Chevrolet Venture Passanger ???????????

Bad water pump, stuck thermostat or radiator fan motor not working.

If it has one it would be on the bottom of the radiator. Most cars and trucks today don't have a plug or valve.
You are expected to use a recycling machine to flush the coolant.

While engine cold, open your radiator cap, start the engine then engage your throttle to ramp up/down your rpm from idle to 2000 or higher for about 15 seconds then top up then coolant. Repeat the above steps 2-3 X. Or after replace the coolant, just do short trip/travel with your car, after engine get cold, top up your coolant to normal level. Now your radiator is free of air. It is easy.

sounds like you may have a blown head gasket or cracked cylinder head.

Thermostat Removal & Installation To Remove:

1. Before servicing the vehicle refer to the precautions at the beginning of this section.
2. Partially drain the coolant, (until the level is below the thermostat).
3. Remove or disconnect the following:
   • The air cleaner and duct assembly
   • The crossover exhaust pipe
   • The radiator hose from the thermostat housing
   • The thermostat housing bolts
   • Any remaining sealer from the bolt threads
     
     
   • The thermostat housing
   • The gasket
   • The thermostat

To Install:

1. Install or connect the following:
   • The thermostat
   • The thermostat housing
   • The gasket NOTE: Apply RTV sealer, GM P/N 1052366 or the equivalent, to the thermostat housing bolt threads.

     1. Torque to: 18 ft. lbs. (25 Nm)
   • The radiator hose to the thermostat housing
   • The crossover exhaust pipe

2. Thoroughly inspect the cooling system for leaks.

Check your coolant level in the overflow as well as the radiator. Be sure to only check the level with the engine cold. The system is under pressure and removing the cap when hot could cause sever burns and injuries. If you have to fill it be sure to use a 50/50 mix of dexcool and water.
