when you replaced all of that stuff on the vehicle did you make sure that you don't have a vapor lock in the highest anti-freeze line? to fix run vehicle with line disconnected so air can escape then reconnect. if that dont work you will need to put a T splice in the top anti-freeze line so when the vehicle is running you can open the valve and let air out.

the cooling system has to be bled. Did you bleed the cooling system ? first you fill the radiator with coolant and water. Then turn on the engine and and run to operating temperature. Most cars have a bleeding screw located at the thermostat housing. Turn of the engine and with a fairl long screwdriver turn the screw counter clockwise and remove the air until coolant is the only thing coming out. Refill and repeat procedure.Refill with coolant until full. Be careful not to burn yourself with the steam coming out with the air.

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

You most likely have air in the system. These things can be a royal pain to get the air bleed out of the system.
Look back next to the brake booster and you will see a rubber tube with a screw cap in the end of it(this is the heater bleed), also on the front of the intake area you will see a black tube with an allen sloted cap.
Remove the slotted cap and screw the screw cc on the rubber tube. Add coolant to the coolant jug allowing the system to equalize until no more coolant can be added. Add as much coolant as possible to the engine fill( the sloted cap near intake). The heater air bleed will remain open.Replace the engine fill cap.Start the engine and turn the heater to MAX position.Close the heater air bleed when a steady stream of coolant comes from it, during engine idle. Allow the engine to idle for five minutes, add coolant to the degas bottle as needed to maintain the cold fill MAX mark.Reopen the heater air bleed to release any entrapped air and close again. Maintain engine speed of 2,000 rpm for 3-5 minutes or until hot air comes from the heater.Return to idle and verify hot air is still coming from the heater. Set the heater temperature setting to 75° F and allow the vehicle to idle for two minutes.Shut the engine off and allow to cool.After the engine has cooled, add coolant to the degas bottle to bring the level to the cold fill MAX mark. This should have the air out of the system.
