Okay, I've had this problem for a while. Whenever I drive normally everything in my car is fine. But when I race I leak out coolant from my resovour. Why? I've replaced the cap b4. Nothing changed. HELP!!!!!??? :dunno:
Hmmmmm, sounds like combustion bubbles... might want to check it out, you may have lifted a head gasket causing cylinder pressures thru the coolant system.
I had the same problem and removed my thermostat because the motor starts to evaperate the water causing to much pressure. or it could be the head gasket under high boost.
