I have a 2004 Chrysler Pacifica. Recently the radiator hose came loose. My husband was able to get it back on, but not well. So, it came off again. Then I helped him put it back on the second time , which seems to be on very good. He put in more antifreeze and then drove it about 5 miles and it overheated!! The hose was and is still on tight and there doesnt seem to be an apparhent leak.
What could be wrong?? Someone told me to take it in for a pressure check. Someone else said it may be my waterpump. Do water pumps go out that easily?
 
Fill the reseviour tank. Start the car. Check to see if the antifreeze is exiting the reseviour. If it is, your pump is fine. Check to see that the thermostat is opening and closing properly.
 
Also you most likely have what is called air lock. Its when air is trapped in the cooling system. Air doesn't cool Therefor it over heats. If you look on the intake where the upper radiator hose goes in There is a bleeder screw. Its a brass screw size 3/8 loosen it then fill the coolant when coolant starts coming out then it is full. if you don't do that you ll NEVER get the air out. Also squeeze the upper radiator hose then open the bleeder to pump air to it.
 
beyond a doubt you have a trapped air pocket in the cooling system there should be a bleeder open it until coolant comes out and repeat the process and the best tell tell sign is when it blows hot air out at idle then its a given the air air is out
