Alright, my car is over heating The top radiater hose gets hot but the bottom one is ice cold. at an idle moving or whenever it still over heats, we thought it was the headgasket, but it holds cyl. pressure and coolant pressure. but we are gonna dye check it for exhaust gases tommarow, but intill then i need some input.Correct me if im wrong there is a bleed screw on the front of the motor and there a cap with a clamp on it for the heater core correct? should i try taking the thermastat out completly and seeing whath happens there? perhaps a blockage?


1. the thermastat is good and new
2. water pump is fine
3. air has been blead
4. vacume tank has a level in it and is not sucking air in from there

 

that sounds like a thermostat problem. Is your A/c cold or luke warm? Can your heater blow hot?

ninja edit: are you boosting?

 

take off the thermostate to see if it works,


also what you can also do, boil the thermostate in your kitchen and see if it opens and at what degress... if you have the tools

 

heat is ICE! cold and the thermastat did open when i boiled it but i did replace it anyway with a lower one, yes im also boosted, details on that in my sig, but im gonna go to think its a blockage

 

You ahve are in you system, why I dont know. It happend to me all of the time, bad head gasket. You can fix that in a day
