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.

yes I would use air to blow through the heater core first. The blend door is just the mixing valve on the inlet hose at the firewall. The cable runs from your heater control to mixing valve, so when you turn the heater control the cable pulls the valve open so there is hot water running through the heater core. When you have the control set for cool air the cable pulls that valve closed.
You should be able to remove the inlet hose and see if the valve is opening and closing like it should. Or maybe you just need to check that the cable is hooked up right. -------------------- Bust a Deal; Face the Wheel.

And then I will add radiator flush to the heater core and let it sit for a few hours and then blow all of that out and rise it out then put coolant back in. |
