Low Tech test

With the system cold, make sure full of coolant (or plain ol' H2O), leave radiator/expansion cap off. Start engine, let warm a bit and gently rev it. Often a blown head gasket will build enough pressure in the cooling system to force coolant out the expansion tank.

If a fair amount of coolant comes spewing out the tank, chances are good the gasket is blown.
