Is the thermostat in backwards?

Replace the radiator cap, and MAKE SURE that its a cap of the type where the check valve (the little metal disk in the center of the rubber gasket) is retained by a SPRING.... NOT one of the kind where the little disk dangles freely- those are for conventional "recovery bottle" systems, not for the Intrepid type system where the coolant tank is pressurized just like the engine block and radiator are.
