    Soo I replaced the thermostat in the GXP today and I need to bleed the air bubbles out. Is that something that can be done or do I have to wait for the bubbles to work themselves out through the overflow tank?

    I just run with the cap off the tank for a while then shut it off and let it sit for a bit. That lets it bubble up into the tank, top it off, cap it and that's pretty much it.
