Have you checked the thermostat gauge on the dashboard. Is it operating at normal levels or staying on the "c" for cold. Look at how the gauge is registering next time you are out and have driven long enough for the motor to warm up.
no totally different engine, and engine bay lay out. Smaller engine (civic) cant cool a bigger engine (accord)
HI, I would suggest you check the ignitor .My 1993 Honda Accord LX had the same symptoms. Mary
it has a partially clogged heater core.replace the heater core
Purchase an AEM cool air intake
if this system uses dex-cool flush the system
To keep the transmission fluid cool. Without one it would overheat.
Your coolant level is low.
low on anti freeze or blockage in heater coil
It needs a rebuild.
The heater core could be burnt out. Make sure your antifreeze is full and your switches on the dash are working. When you move the switch from cool to warm you should be able to hear a difference. If you don't the door/flap may not be moving.
increase the air flow to your engine. the cheapest is probably a cool air intake
Yes. With no hot water circulating, the heater coil/exchanger will quickly cool down to ambient temperature and the fan will blow cold air into the cabin.
