I have a coolant leak on a 2005 escape. It's leaking on the block thing that has the radiator hose, heater core hose along with a 3rd hose all combined. My question is where does the 3rd hose go? It goes under in intake runners but I don't see where it goes from there. I thought it it might go to the oil filter cooler block but not sure. It's hose #11 in the diagram. Thanks for any info.
