As part of my preventive maintenance project, I am changing over all the hoses this weekend including the "expensive" heater hoses and heater control valve. The valve in my car has a round metal vacuum housing, but the new one purchased from dealer is made of plastic. I heard the plastic one tends to erupt easily. Will the eruption cause massive coolant loss, or just vacuum failure? I am not sure if I should keep using the old one and hold on to the plastic valve as a backup. Any comment on the valve and suggention on dos and don'ts of my project is very much appreciated.

    The water goes through the plastic valve body, not the vacuum bellows, and all the valves (OEM or aftermarket) have plastic. You will be fine as long as you realize that after eight years or so of hot water flow, the plastic tends to embrittle and may crack. If you change it, no problems.
