I have an 03 civic ex model no upgrades all stock. when I floor my engine to high temp. the coolant starts to fill the reserval untill it starts over flowing and spraying out. at first I didn't know where it was coming from so I put a little bit of stop leak powder. same problem continued. so I bought a new radiator and new thermostat gave it a flush and put it all back together. now its still with the same situation, coolant still coming out of the reserval in high temp. the reserval is all good no holes or cracks. my fans are working. what can I do next? pls help!
