I had a problem with mine where I would drive the car and occasionally I would get a whiff of antifreeze open the hood and to find nothing a couple of hours later I would go out to use the car and noticed a puddle of antifreeze under my car and it was between the radiator and the block. After two months of searching I notice antifreeze around the thermostat housing doing all the minor repairs (new hose, Tstat housing & gasket) all to no prevail. It was frustrating and with help from members they guided me to the problem which was a hair line crack in the thermostat housing on the intake manifold and when the tstat was out could not see the crack but when you crushed the gasket it would spread and leak so do not rule out your intake.

Did you check the hose running to the reserve/overflow tank? It would not show on a pessure test and would leave a puddle after running and cooling down.

I had a similar problem with my 91 cougar. What was happening is the plastic side tanks and the aluminum radiator core expand at different rates when they heat up/cool down. Mine would only leak while the engine was warming up or cooling down and only when it was below freezing outside. I could drive it as long as I wanted and once it was warmed up, it wouldn't leak a drop. Then I would shut the car off and it wouldn't leak right away, but about an hour later I would have a puddle under the rad. I ended up just throwing an egg in the coolant and it never leaked again until I lost oil pressure on it and took the car off the road. You could try the same thing, or replace your rad, but I'll bet yours is doing the same thing mine did.

Ditto on the radiator. Had same deal on 2 different birds. The O ring that goes around the end tanks on the radiator is probably ate up. Mine only leaked when it got really cold overnight, after the car heated up or temps were warm it wouldn't leak. The rubber shrank up enough to cause a leak when it was cold. New radiator isn't that much and it is easier than having a shop try to put the tanks on the ends (dissimilar metals). Then you can change the hoses and new anti freeze.
