As I discovered with my Mountune radiator there are lots of coolant hoses on the front of the engine in close proximity to the fan shroud. With mine the thicker 3 pass radiator had some ribs on the shroud rubbing against the coolant hose from the bottom of the resevior. It took some finagling to get the hose clamp off at the junction over the thermostat and a 108 dollar assembly to get the require molded hose but it's now leak free. BTW, replacing the entire hose assembly would have required removing the entire fan shroud so I chose to just replace the damaged hose. Note a friend who still has full use of his hands was able to position a wire tie so that the fan shroud is well clear of any hoses on the engine.
Anyhow I expect that if you closely examine the coolant hoses in the find of your engine you will find that leak. As for replacing the damaged hose I'm willing to bet that you'll wish these cars were built like cars back in the 70's and 80's with good service access. Had a 1976 Honda Civic and when the timing belt broke it was a 1/2 hour job to install the new one. The inner fender liner had plugs covering access holes for every single bolt on the timing cover.
