94 ranger leaking

[sunnibear]

Alright we got this truck only a year ago.. it is a 94 ranger it is the vehicle used only for work (5 miles one way). It just all of a sudden started leaking coolant fluid, not just leaking running out. It starts to run about 2 min after truck is started, vehicle at this time is not over heating. If you turn on the heaters it blows steam in through the vents. It is happening on the passenger side in back of the tire. I have checked the overflow container there are no leaks (coolant is coming from area under it.) I have checked water pump, water pump hoses, radiator hoses, and overflow hose. There is no coolant in the oil. Other then that it runs fine. Any suggestions on what to check what it could be? thank you

Heater core. The coolant you see hitting the ground is probably coming out of the A/C drain.

The water that is coming out is green. the overflow resevoir does get dry, the radiator hasn't. The A/C hasn't been running (A/C is the only thing that hasn't or doesn't work since we got it a year ago).

Definitely heater core - my B3000 did the exact same thing. Don't know about the earlier series but I had to remove the entire dashboard to get to it.
