Thanks to everyone that replied to my last two problems with the bleeding of the coolent system and my idle problem. I cleaned the TB, IACV, and then at the very end had to end up adjusting my idle adjustment screw by one turn. Now my idle is perfect!! My other problem with bleeding the system was fixed due to me coming to terms with being an ignorant first time honda owner. I was looking on the upper cooling hose, not the bottom hose. I have one last problem that I cant seem to figure out. I have no heat!! If I open my heater and squeeze behind and infront of the heater valve the level of the coolent moves up and down. So I cant figure out why I do not have cooling flowing when my valve is all the way open, car is hot, and fan is on full blast. Any ideas on how to get fluid moving back to the heater core? Perferably a fix where removing the actual valve is the last option....

 

Did you replace your thermostat? If not and that is the problem you'll end up having to bleed your coolant again

 

Is your blend door working properly?

 

I do not think it is a thermostat problem because my coolent flows nicely acrost the radiator. I do not know what the blend door is...... Again my car is a 93 honda accord with an automatic trans.

 

When you select a heat setting, a door is moved to a position that varies the amount of hot air that will be supplied to you through the vents. These doors can become stuck(warpage or debris) or the controls break.

If you look at #10 in the bottom middle that appears to be the control rod for the blend doors. But someone more familiar with the CB chassis will know better.

 

I am not going by the air coming out the vents as much as I am going by the feel of the heater core tubes them selfs. I am actually reaching my hand down and squeezing them when the engine is hot and running, and there is not hot fluid flowing. Is there such a thing as the heater core to become vaporlocked?

 

Thermostat for sure.

 

What is the temp of the hose on the front side of the valve vs the back? Slip the clip off the cable, remove cable from the valve and move the lever by hand. Does the hose on the back/firewall side get warm....now what is the temp of the "other" hose from the heater core. Once you know you are getting warm/hot coolant flowing through the heater core then the blend door adjustment can be checked. If you download a service manual, 15-30 thru 15-34 (?) are the sections you need.

Edit: did you bleed the cooland with the heat on? or at least with the **** to heat.

 

stuck open thermostat probably? air bubble still trapped in system? car overheating? faulty heater core valve?

 

The heater core has a valve on one side only. If you squeeze the hose on either side of the valve coolant will be pushed from the radiator. Also, this tells you that the heater core has coolant in it. If you open the heater valve ( set the **** to HOT ) and you can watch the linkage on the valve move but the other side of the valve doesn't warm up, the valve could be broken internally and not actually moving with the linkage.

 

Anyone have any other thoughts?

 

Ok, are you saying that both hoses to the heater core (in and out) are not getting hot/warm even though the temp gauge/rad fans tell you the enigne is at temp? The hose before the heater cont valve is also cool. Then yes I would make sure the valve is open and open the bleeder. If the hose before the valve is hot but the others are not then I would pull and inspect the valve.
