Has anyone had a coolant leak on the passenger side firewall? I pulled the fender liner and it doesn't seem to be coming from the heater core lines them self but rather it's just dumping out of the drain below. Also there is a coolant smell in the cab, I haven't lost heat and there is not any fluid in the cab. Is this the heater core itself?

 

It's the drain for the heater core if anyone else runs into this. Time to pull the dash.
