My first thought is that you may have a bad hose at the bottom of the radiator, or may just be a clamp problem.
With light in the morning you may better be able to see the problem. It may help to go ahead and heat up the 
engine, as long as you have access to enough coolant/water to keep things safe, so that you can get the
leak to happen while you can see it.

> Drove over Stevens Pass to Seattle for a Drs. appointment and my '84 was running like a champ.  Between Monroe and Bothel my heater started blowing cold.  I got into Bothel and bought antifreeze and water from a grocery.  Added them and drove a little further but still no heat. Bought 3 more gallons of water and started adding them as the engine ran. Finally I saw fluid running out of the front.  Passenger side under the radiator. It's too dark and I'm too tired to look at it tonight but I need to get it resolved early tomorrow to get to my appointment by 11:30.  I'm using WIFI at Denny's around the corner from where I'm going to stealth camp in the QFC parking lot on hiway 527 and the 405. Can anyone guess what I'm going to find and how hard it will be to fix. I've never explored that part of my van much before. Anyone nearby that I could hire to help?
