any info on the problem of leaking coolant for 1997 f-150 4.2 l manual .... dripping from the bottom of oil pan......not really coming from the water pump or hoses....mainly from just ahead of the bottom of the oil pan way up in there. getting progressively worse, although sometimes a few drips yey other times enough to see from 15 feet away. engine coolant in resivoir not too affected.

 

Check the hose between the water pump and the radiator. Especially the fitting on the water pump itself. Also look around the underside of the water pump for wicking, or signs of leaks. Like mineral deposits, or white marks etc.

well now that youve edited your post, are you sure its coolant? and not just water? Also could be your heater core has gone, it the leak is more twords the back passenger side of the engine bay.
