Coolant over flowing (could be force induction related???)
 

Has N E 1 had a small problem with not over heating but having there coolant overflow tank filling up and splashing antifreeze over the place?
I can drive the car for miles, longest ive went was 80 miles and this was in rush hour traffic also, and the tank never over filled and everything was fine…..BUT….when I get on it hard, it seems to do this, yesterday I was making a short video and it was doing it bad, eventually the temp needle started to rise but would fall when I step off the gas.
Seems like a thermostat problem but I just replaced that 4 months ago…..could it be that the one I have is not opening quick enough, I think its rated at 180-190 degrees….and when I get on the car hard, the engine is heating up quick, so I just ordered a jackson racing 160degree thermostat.
Just wanted to know if anyone else had a similar problem before, thanks.

Also I know….ill post the video soon as its finished ;)

take the thermostat out and see what happens. then its a straight flowing cooling system.

Do you have a d-series motor by chance? I am guessing head gasket.

Re:Coolant over flowing (could be force induction related???)
 

no its an f-series (accord)
headgasket....i dont have any of the headgasket symptoms.
like i said i can drive it normally and its fine. only when i get on the car hard does it do it, but it still doesnt over heat, the over flow tank will just fill up.
the oils fine and the antifreezea fine.

The overflow tank filling up is a headgasket symptom. Trust me I had the exact same problem a few months ago, car would drive fine and never overheat, but the overflow tank was filling up. It only did it when I was boosting and then eventually it started doing it every time I drove it.

To check this take your radiator cap off and idle your car, hold the revs up until it gets hot enough for the fan to come on, if you see lots of little bubbles coming out your radiator it's your headgasket.

its either a headgasket or...like me, cracked sleeve :-\

Re:Coolant over flowing (could be force induction related???)
