So my car has been overheating, and when it first started overheating the coolant would bubble up and the temperature gauge in the car was not even close to the red zone when it would boil. The head gasket has been replaced, along with the cooling fan which got rid of the bubbling and it no longer boils when the heat gauge is at about halfway. The water pump has been checked. My repair manual says that you can check the thermostat by feeling how hot the upper hose on the radiator is. If its hot when the engine is hot then your thermostat is stuck closed. I let the engine get up to about the red line and checked the hose, It wasn't cold, but it wasn't extremely hot either (you could leave your hand on it and you wouldn't get burned). I'm not sure how "hot" the hose is supposed to get, so if you know that would be a big help.
