I need to know the part number for the recirculating pump to the heater monovalve (the piece connected by three hoses just under the plastic resorvior) for my '87 W124. Can someone help me? I found out that is where my coolant leak comes from, and not the hose I originally thought. It nearly stranded me on the side of I-95 this afternoon. Lucky I had a bottled water with me in the car.
