RSX No Heat?
I have changed the radiator, the heater core, the thermostat and the hoses on my 2003 RSX and the heat still doesn't stay hot when i stop my car. Can anyone tell me what the hell is the problem here? It takes a long time to get and stay hot. When i drive it gets hot fast but when i stop it gets cold just as fast. Help me please.

Have you bled the air of the cooling system?
Sound like you've got air in the system. |
Heater core?
|
^ what he said. Or bad thermostat.

Bleed the system, pressure test it and go from there, fans kicking on after it gets to operating temp?
|
Did you check the heater core coolant control valve?
Sometimes they stick or do not fully open. Also check the cable that controls the valve, is it sticking binding or broke. The valve is typically in the coolant hoses going to the heater core. |

Well i had a mechanice change all those parts in my car. I would like to think that he checked that valve already? I have no idea my friend.
http://www.acuraoemparts.com/delray/...All&vinsrch=no It's part #1 below and look at the cable and lever and move the heat from full hot to full cool. You should see the lever on top move ~1/4 turn. http://www.acuraoemparts.com/delray/...6m01_b1730.png |

BTW, that valve is mounted on the engine side of the firewall.

And is it easy to see from looking from under the hood? What exactly would i be looking for to see if it's not working the proper way?

When u say bleed the system, do you mean the ac system?
When the radiator fluid is changed out on most Hondas & Acuras, the system has to be bled, or "burped," to get rid of air in the system. On the RSX, remove the radiator and reservoir caps. Start the car and turn the heater all the way up. Let the engine run and bubble out any air (from the radiator neck) for 10-15min. until there are no air bubbles. Try that before adjusting the heater valve. G/L. |
how did it turn out

I am going to move this to the RSX section to keep everything organized, but wanted to bump it so the re-direct from Car Talk was seen...

My 04 rsx also has this problem.:whyme:
