I pulled the two hoses going to the heater core off because I suspected the leak would be around there. No leak there.
However, when I looked, the hose running sort of perpendicular underneath had completely come off from wherever it’s supposed to be attached. For the life of me I can’t figure out where that hose goes. It goes from the front, along the driver’s side of the engine, then turns left towards the passenger side and into the engine or something.
What hose is this? Can I reach it without taking the intake manifold off?
[edit]
Found the connector, hopefully I can reach it w/o taking off the intake manifold:
