Dodge in its infinite wisdom has the timing chain driving the water pump for this particular model. So the weep hole is located next to the thermostat housing since there is no way to inspect the water pump housing with out disassembling half the engine. How this weep hole is tied to the water pump I don’t know. All I do know is when I pour coolant in it leaks out this hole. The car will not hold coolant. Also when I blow into the upper radiator hose I can feel air coming out of this weep hole. According to the DIY manuals this weep hole is how you can see if your water pump is functioning properly. Well the water pump has been replaced with genuine MOPAR parts. Also I am getting coolant in the oil pan. The car seems to be running fine without any warning lights. Just need to figure out what is going on with the cooling system.
