My Honda Civic overheats after driving for about 30 minutes. I have replaced the radiator thermostat and temp sensor. I have also taken out and checked the water pump and it is fine. I even ran the car without the thermostat and the problem is exactly the same. My fans are turning on correctly they turn on every time I turn my air conditioner on and turn on when I come to a stop I have good compression in the car runs good I don't have any water in my oil and I don't have any oil in my water and my tranny fluid is full. I am stumped.

Where is the temp sensor you replaced located?Also what is the actual temp your fan turns on if you sit and let it idle till the fan comes on?

Temp sensor is right above thermostat housing and fans are turning on right about 175 degrees. Plus or minus a couple. I'm sure it's not the fans because it will get hot when I'm driving at high speeds as well as stop and go. But it does take at least 20 minutes or more before it gets hot

The only time I lose coolant is after it gets hot and starts to bubble/foam out of the top of the overflow

So what temp does it start boiling over the cap?I had a honda that they went thru everything and turned out the radiator cap was bad causing it to loose coolant and overheat.
