Question about 2003 Honda Civic
I also have an 03 Honda Civic and it also overheats sporadically with no rhyme or reason. I have changed the thermostat and the problem still persists. The other major problem (I believe its related) is that the heat will not work unless unless the accelerator is pressed (once you get going on a highway). I have taken to a couple mechanics and called HOnda and they claim that there is no way to diagnose the problem unless it is happening when they look at it. Which is nearly impossible for me to get it to them when its happening. The heat issue is like that all the time though and with winter rolling in (in PA) I desperately need an answer. Have you found out anything? Any help is MUCH appreciated. Thank you!
You have air trapped in the heater core make sure the radiator is full put the cap on half way and let the engine idle until you hear the cooling fans cycle twice make sur the heater knob is all the way over on hot blower off if this doesnt do it do it again i work at honda and this is what the bulliten says
