2006 coolant leak?

06 4.0L ~70k miles. My coolant level keeps dropping but I can't seem to find a leak anywhere. The thermostat housing looks new although I haven't changed it. Got the car at 50k. Hooked up the pressure tester and it held strong. There does appear to be a little bit of corrosion inside the fan shroud at the bottom but I really can't see in there well. Any ideas?

If you can't find a visible leak , It may being burned . How does it run when you first start it in the AM ?

check the plugs, if one is always cleaner than the others it is burning it in that cylinder.

mines does the same, i took a sample down to ford and firestone and they checked my vehicle and everything was fine. they told me that if you use the a/c it drips water even when the vehicle not being used like a/c hanging out from your window house window drips water on the ground same thing, but my coolant level were normal so mines might be the same situation as your or not

this copper stuff works great for fixing small leaks in the head gasket or cracked head. Add it straight to the antifreeze. I did it a year ago-- no more antifreeze usage..

Thanks guys. I'll look a little harder for a leak but I bet yall have hit it on the head. I guess I just need to keep a better eye on it.

I think it must be burning then. I'm going to check the plugs. It runs pretty great all the time cold or normal EOT.
