95' 525i. Kind of concerning haha. I have tested the head and it passed. I changed the water pump and thermostat about a month ago. Ive had to bleed it 1-2 times since then, due to overheating. Every time, just air. No more overheating (hopefully) but now these spots under the front passenger side of the car. Oil cap and dipstick are clean. Also it is very cold here this time of year, if that adds any value. Any ideas? Thanks

Ok George. We are going to need a few more details in order to help.
1. Model and year of car
2. What work has been done? New head gasket?
3. Is your coolant level dropping? I.E. leaking onto your driveway? If so from where.
4. How was the head tested?
5. Anything else relevant?

I did answer a majority of those questions in the OP. 95' 525i. No new head gasket to my knowledge. I tested with one of the combustion testers with the dye. Didn't change color. No coolant level drops. front passenger side.

Maybe a crack in your radiator or a hose? You could use a coolant UV dye to trace the leak, if you haven't done so.

Why speculate? Lift it and look.

Also those spots look to me like oil that has been dropped on a wet surface or seen condensation form on it, not coolant.
