Check with Detroit Muscle Technologies, they were going to reproduce the rubber valves that are inside the unit.Is this salvageable. My OEM heater control valve has begun to leak coolant. The housing parts appear to be in excellent condition w/ no cracks. Response at the dash controls is spot on. The rub is where to get gaskets to repair it. Are there any underlining failures I need to look for. If it didn't work so well I would just replace it w/ a all steel unit. The steel units just don't perform well as they have less than desired sensitivity at the dash controls.
