Already replaced pressure cap and looked for drips. Any ideas?
TIA,

What color is the engine oil?

If you have recently flushed the coolant system, drained the coolant
system, or otherwise refilled it, it takes a while (on the order of
days or weeks) to work all the air pockets out. This will appear as
lost coolant but it is just bubbles burping out.

Maybe a pinhole leak somewhere. Maybe leaks only under pressure. Have a
look see with engine running. No white smoke or balky starting in the
morning?

Starts and runs great; no smoke. Will look again for pinhole.
Thanks

You can purchase a dye liquid to mix in with the coolant. It's
extremely fluorescent under black light. Drive around for a while. Then
borrow someone's disco lamp (black light), wait for night time, and
poke around in the engine compartment and under the car to see if you
notice any glowing dye.
Failing that, have you ever tried mixing in a couple of tablespoons of
ground black pepper to your coolant? The flakes of pepper are pushed
into pinholes by pressure in the system and they often block the hole
effectively (and very cheaply).
Good luck!

When you first noticed the low coolant, did you notice it because the
low coolant light came on or while you were checking fluids under the
hood? Depending on that, if it was the blinking light, you might have
other issues by now. Driving on low coolant too long will effect other
parts. Do the glow dye trick. Your water flange on the side of the head
could be warped. Weep hole on the water pump. Overheating the plastic
parts on the radiator would split a seam and boil off before it hits
the ground. I have seen dozens of leak conditions. You could have a
leaky head gasket that is allowing coolant to go into the cylinder just
enough to burn off without effecting the oil or smoke exhaust.
I would look a the driver side water flange on the head first. They usually
crap out around 6 to 7 years.
