Coolant level geting lower
 

Ok so for awile ive noticed at the very front of my 05 f250 there has been a small leak i asked about it b4 but never figured it out honestly ive looked at the liquid and its clear and has no smell but ive noticed my coolant level is a little bit lower than normal i usually keep it at the minimum line and now its about half inch below that. I just dont even know where to begin ive tried finding where the leak is but i cant find the exact spot, it kinda looks like the bottom of the radiator but what else is in that area that would leak a water like liquid? The coolant level is what has me concerned and its cold as gell in ohio right now and getn colder so workn on it usally only lasts about half hour then gotta come in and warm up again.

Did you feel the stuff leaking on the ground?
Does it feel slick, and does it smell sweet, like coolant?
Or, is it very clear, no smell and feel like water?

Is it possible it's simply water collecting on the a/c unit and then dropping on the ground?
This happens a lot to me in the summer....don't know if it's even possible in the cold of winter.

If it's coolant, could it merely be your clamps need tightening on one of the hoses?

I know those leaks are sometimes very hard to pinpoint.

It's clear no smell it's like water, every since I've owned it I've thought I heard the ac unit running weather I'm using heat or ac what would cause this or how can I test it because I know I've had a lot more liquid on the ground than the amount of coolant that I'm low on.
