i was overheating in my 95 civic ex. i bought the car supposively with the timing belt and waterpump changed. so after about a year with the car the overfill tank was getting full and overflowing and i was overheating. so i did some maintence, i changed the hoses, coolant flush, thermostat, radiator, cap. i let the car run with the cap off for about 30 minutes and i still get some foam or airbubbles. i just cant seem to get the air out. i still overheat sometimes after heaving driving also. what else could be causing this never ending air? headgasket? warped head? my spark plugs look good, i dont have any coolant leaks, i dont have smoke coming from tailpipe, anyone got any ideas?

 

Get the front end as high as you can.Jack up the front end or park it on a steep hill and bleed the system.

Have you done a leakdown test? The headgasket may have a small leak.
