If your thermostat aint seized shut, its your heater core. You need a new one. Your heater core is another element that makes the antifreeze move in a circular motion. If it aint moving in a circular motion, your car is overheating, meaning that it could be your thermostat, heatercore, or waterpump, but I think that its your heater core. If it is your water pump, your check engine light would come on.

How do I bleed the cooling system?

Turn the heat control to max and remove radiator cap - add coolant as much as possible. Make sure overflow container is filled to correct level - then Start car and run - after the thermostat opens water level may go down some - keep adding coolant till it is totally full. Turn engine off and put radiator cap back on tight.

2004 impala overheating. How do I know if my water pump is bad?

Let the engine cool down then remove the radiator cap. With the cap off, start the engine and let it idle. Watch the water in the radiator. As the engine heats up, the water will rise as it expands during heating. When the thermostat opens, (and this may be your problem) the level will drop, and you will be able to see the water recirculating through the radiator. If this doesn't happen, the thermostat is not opening (stuck closed). If you can see the water recirculating when you start the cold engine, then the thermostat is stuck open. Either condition will cause overheating. Start with the easy fix first (thermostat) before going to the water pump.

the engine will heat up quickly, and the radiator will stay cool if its stuck closed, if its stuck open engine will warm up slowly and not reach operation temp

Air lock cooling system

Not sure I follow your wording on the different temps. If the system is full of coolant and working correctly, the thermostat should open at 195 degrees which would be several miles down the road. Once the thermostat opens both radiator hoses should be warm. If the water pump is not working the engine will get hot very quickly.
Have you tried running without the thermostat to see what happens ?

2002 chrysler 300m special overheating

Only thing I do not see in your list and the most overlooked is a new radiator cap. The radiator cap itself is extremely important to regulate the pressure in the system and just something as simple as this could be the problem. If this doesn't I would have to know more. Is the heat working? If not could indicate a clog in the heater core. When you stop does the coolant overflow into the overflow (common condition when the radiator cap) is bad. Since you have done everything it is my guess since you replaced the radiator you used the old cap.

Should my thermostat be removed?

No It is there for a purpose and the problem that makes you consider the removal of the thermostat should be fixed . It is there to bring the coolant to correct operating temperature as quickly as possible and then to regulate the flow through the radiator to maintain a constant temperature. The easiest check for a thermostat problem is to start the engine cold and let idle for around 10 minutes Place your hand on the top radiator hose and if the thermostat is ok you will feel the hot water start to flow through the hose. If you have the radiator cap off you will feel the water heat up and you may see the water start to flow as well.. Over heating problems can come from blocked or partially blocked radiator cores, leaking head gaskets or cracked head, thermostat, old soft hoses, timing , air/fuel mixture, blocked exhaust, overload /over speed , wrong gear resulting in excessive rpm's, coolant fan not working, viscous fan hub not driving fan, loose fan belt, blocked fins of the radiator( plastic-grass-mud)

Trying to burp cooling system, but when car heats up the coolant shoots out of the radiator like a fountain.. Thermostat is removed, still heats up

You are correct in your suspicions.
The thermostat blocks flow thru the radiator to help the engine warm up. The coolant still flows thru the block with the thermostat closed. If you remove the thermostat the cooling system should flow thru the radiator and stay below 160 degrees if the air temp is below 90.
If the thermostat is out and the engine is getting hot at idle speed, either the water pump has failed, or there is another blockage in the engine block.

I have a 1994 Jeep wrangler 6 cylinder. I replaced the cooland and therostat and it opens like it should at about 100 but the air is still cold. Is there something I overlooked?

Hello! Thermostat should be a 190 may have an air blockage...Remove radiator cap start engine and leave cap of until all air bubbles are out (even after thermostat opens)...Cap and test for heat...if there isn't any heat...When that thermostat opens and hot water flows through the upper hose of the radiator that hose will be hot and hard..If you feel the heater hose only one will be hot which means that nice hot water is not passing through the heater core...That could be due to blockage or the control in the car isn't opening the valve on the core...check to see if the heat control is opening the valve...If it is, I would suggest that you purchase a back flushing kit ($10) A plastic tee fits into the inlet heater hose and a garden hose is then connected to the tee...Drain the radiator, remove the thermostat, and turn on the this with heat control on high...The system will back flush out of the top of the radiator and hopefully clean the blockage...Reassemble ...Cap off the tee (cap is in kit)...Install thermostat (190) Is a better choice...Refill radiator...Start engine and leave the radiator cap off until all the air bubbles out............At that point you should have heat...Guru...Saailer

Over heating, thermostat replaced, radiator, engine, and heat core flushed, no water in working, water pump flushes water thru.

You may have air in the system. Let the engine run with the radiator cap off until the thermostat opens. Have someone then get in the truck and bring the rpm up to 1800 to 2000 rpm and hold it there for 15 to 20 seconds while you top off the system with coolant and put the radiator cap tightly back on. Then bring the rpm down to idle and road test the truck. DO NOT BRING THE RPM BACK DOWN TO IDLE UNTIL THE RADIATOR CAP HAS BEEN INSTALLED COMPLETELY. I suggest replacing the radiator cap at this time also.
