Do you see an external leak? If not, it is possible you have a leak internal to the engine. A head gasket leak can be causing your problem.

Time to test for a leaking head gasket.

How do you know it’s running hot? Is that only based on the temp. gauge?

If you are unable to find a leak, I would look into a head gasket issue. Many shops can do a quick sniff test (using a special tool) to find exhaust gases in the coolant.
