91 Aeristar coolant leak
Hi,
My van is leaking coolant from somewhere in rear of engine. It started as steam coming from vents on a road trip. I added about 1/2 ga the next morning and made it home, where the leak started gushing in the driveway. I figured it was the heater core, and since I live in AZ and I read up on the difficulty of replacing the core, I opted to bypass it. Once I got the lines cut and connected, I added coolant and it started leaking out again. The coolant is running down both sides now, behind the oil pan, even without running the water pump.
Details:
91 Aerostar
2WD
3.0 L
6 cyl
Any ideas?
Thanks,
Mike

I don't know that this is proof. I had a head gasket on an Escort go bad once. It broke between the coolant chamber and the outside. I could only fill the radiator up to a point and it would come out of the front of the engine.
On the other hand, the Aerostar my brother had did develop a leak in the rear freeze plug. He had to keep stopping and adding water until he got it to our Dad's house. We opened the doghouse and found a hole in the left freeze plug. It wasn't too hard to replace. I hope yours is and easy one. Post what you find.

coolant leak resolved
I brought the van to my mechanic and he found that a couple of freeze plugs were leaking, one behind the tranny and one next to a motor mount. They won't be easy to change. Fortunately, my mechanic is family and the labor will be greatly reduced from what it would normally be.
