Hey Yall,
I have just passed the first start on my Mk II Roadster build, and I am trying to bleed the coolant. However, I am having an issue i am unfamiliar with.. I topped off the radiator, put in my fill funnel, and start the roadster. The coolant level stays pretty even until the temp gauge hits 200, and then the funnel starts filling and filling until it overflows while the temp continues to climb. My first thought was a faulty thermostat, but i've replaced it with a new thermo and the issue persists. Could it be an issue with the water pump? Something else i havent thought of? Any tip or advice would be helpful.
