I have drips of coolant on my passenger side floormat. When I got home today and stopped the engine I got a big cloud of steam from the engine compartment also passenger side. Looking under the hood at the top of the passenger side firewall I have two hoses that connect to stubs coming out of the firewall. Lower down in the same area there is a stub that has no hose on it, but was wet and looked very much like that was were the coolant was leaking....but I can't find an unconnected hose that looked like it popped off.
I was thinking that the top two were in and out for the heater core...but what would that bottom one be?
