    My inital thought is sticking thermostat, but I think you'll need a hands on diagnosis to help with this one.

    hey dude i'm afraid that you have a blown gasket. The thermostat is definately bad, but if you keep driving when the gauge goes hot then you will need a new engine(will warp the block)
