No heat through heater, Solved! Options

[rapid36]

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.

It's the second best tool I've seen to bleed a cooking system. I use mine all the time it hold enough and raises the coolant high enough on every car I've worked on. The best I've seen was a vacuum bleeder. It used shop air to suck out the air in the system then sucked in the coolant making sure there was no air.
