Hi there! I have a 1994 celica ST. I put in a 3 core all alunimum radiator and my car started overheating. It was overheating from air being in the system. I blead it out (as far as i know) and my over heating went away. now i dont have any heat coming out of my heater. I only get warm air. my inlet hose going to the heater core is hot and my outlet hose coming from the heater core is warm but no where near hot much like the air coming out of my vents. I pulled off the in let hose and verified that the heater valve was working and it is. I took off the outlet hose and stuck my garden hose into the inlet side for the heater core and turned it on full blast, there was great water flow going through it. Then I checked the blender door by change the heat to cool very quickly and heard the blender door opening and closing. My coolant was topped off as well. The only thing i can think of is air being in the heater core. I jacked up the front of the car and let the air bleed out. I think this is the correct way to bleed out a system.

did you say you tested the thermostat and verified what temp it is opening at? Even if the radiator was oversized the temp of the water going through the motor, and the heater core should always be right around the temp the thermostat is set for.

Theoretically it's possible, heat waste energy stays constant while cooling capacity increases. A lighter can warm up a few ounces of water with no problem, but what about a gallon? Of course an engine puts out a lot more waste heat and has the benefit of having regulation, but being it's Winter if such an event were to occur this would be the time. Of course in a car with electric fans it's even less likely to be an issue. This post has been edited by Box: Jan 13, 2015 - 10:35 PM -------------------- 2001 Miata LS 5-speed
