Please help me identify what this is
I found a slow coolant leak coming from a hose connected to the side of the rad near the bottom on the passenger side. At first I thought this was a heater hose but it does not show up on any ford pa...

That is the OEM transmission cooler and the other is an axillary cooler added on by either the factory or the RV builder. At the other end of the tank there should be another fitting and hose that connects to that other cooler and then a hose from it goes back to the tranny. The coolant leak you see is because that fitting, which is part of the cooling coil setup inside the tank has a gasket that seals it to prevent coolant leakage. In this case it is starting to fail or the plastic tank has developed a small crack. If the tank is cracked, replacement is probably the only option and I doubt if the gasket is serviceable, either. Note that you may have another auxillary cooler also mounted in front of the radiator to cool the power steering and definitely an AC condenser radiator.
