Engine cold. Sat overnight with a drip pan underneath  ( a precaution I
routinely do) and this morning there was about a cup or so of orange
coolant in the pan. Climbeed underneath with a light and could see a drip,
drip, drip every minute or so off of the very bottom corner of the oil
cooler. The cooler is mounted to the engine with one corner down, so
naturally the coolant would drip from that corner. The cooler has been in
that position for eons. Inspected the hoses to the cooler and they appear
dry.

What else might be causing the coolant loss. What is above the cooler that
might be leaking. I can't really see above the cooler without taking things
apart, which I am lothe to do unless abolutely necessary.

Any suggestions will be appreciated.
