Default 2001 Honda Civic EX is Overheating?

There is no leaks, it's not the heater core, it's not the thermostat, it's not the hoses and it's not the radiator cap.

All my anti freeze goes into my reserve tank and then never comes back out. Because it don't come back out of the reserve it overheats and then the fluid in the reserve blows out the top.

I quit putting fluid in the reserve and added to the radiator. And when I look 2 days later my reserve is filled to the brim and my radiator is empty and then it overheats and blows out the top of the reserve. I want to try and get ideas of what it could be here before I go and spend lot's of money. I have heard that it could be a warped reserve tank. Any ideas? I have already flushed the radiator out. All fans are working properly! I've posted this question before but for some reason people must not be reading the whole thing, because they try to give answers when I have already said that wasn't the problem.

Sounds like blowed head gasket. Start the motor, go look at the overflow tank; pull the cap and leave the end of the tube submerged, is there bubbles coming out?

Ok man just start up your car and remove ur rad cap give it some gas and if the colant splash all over and I mean all over your engine and hood will come out like a broken hydrant Defently bad headgasket... Also look for white smoke and white stuff on the oil stick but if you don't find this two u still may have a blown HG. So I removed my thermostat bcuz car was overh and I can give some gas to my car and ull see water runing fast In the rad but will not splash out of it.

Any ways if your car overheats as u said is bcuz low colant. Why does it goes to the recovery thank? It goes there when the car overheats and the system gets to much pressure and as it cool off it comes back to the rad. Since ur car does it before it overheats means that u getting to much pressure on the system and there is only one way left Headgasket! I'm sorry I had the same problem on my 99 ex

If you decide it's not the head gaskets as the previous posts suggest, one thing you didn't mention was your fans. Are, the fans coming on?
