explorer is leaking from the front and rear of the engine. Any one else ever have this problem?

It seems like coincidence (or wind driving or gravity plus channeling) that would result in both the front and rear leak starting at once.

Ultimately you'll probably need to grab a strong flashlight to look around, and doing so under the vehicle might be easier to do at night or at least with the hood shut. If all else fails you can hose off the coolant, let it dry, put UV dye in it then use a UV light to see where it's coming out.

Which engine? A common spot for a coolant leak higher up would be the thermostat housing cracking. Otherwise the water pump may be near end of life, or really now that it's 18 y/o, any hose but most would tend to make a leak in the front or rear, not both except as above. wind from driving or running along the bottom before dripping off.

I don't suppose it's possible you had too lean a coolant mix and freezing weather caused a freeze plug to pop out?

I assume it is running okay otherwise? That would suggest it is not an intake passage or head gasket fault causing the leak. Last would be the radiator itself but usually that just leaks down the front, doesn't look like a leak in the rear of the engine.

After a lot of searching the problem ended up being the thermostat housing. Not an easy fix, but replaced the housing, hoses and sensors. Now fixed, no more leaks.
