Engine Cooling problem
1988 Mercedes Benz 300ce 6 cyl Two Wheel Drive Automatic

How can I Know for sure my coolant leak is my water pump (the pump holds some water at lower hose) and not the head gasket or freeze plug. I can see the water coming from under the A/C bracket and looks to be seeping from bottom right corner of pump; even though pump has new seal.
