finding the source of a coolant leak

For the last few months I've been slowly loosing coolant out of the reservoir bottle and haven't been able to pinpoint the leak. I've eliminated the head gasket as a problem. I recently noticed a small stain that would appear under my WJ after a drive.

Got down and it smells like antifreeze... I'm guessing water pump but can't really see where it drips from. I don't think it's the radiator either, the drip is behind where the radiator is located. Anyone have any ideas?

Check real good around the thermostat housing. I had a small leak there that would drain my overflow bottle in about a month.

If you don't have time to do it right the first time, how do you have time to do it over.

Borrow or rent a pressure tester and you should be able to find the leak pretty easy. Under pressure the leak will usually start to push enough fluid out you will see and or hear it.

check the water pump, hoses, and thermostat. try and follow the fluid up and see where it is leaking from
