Coolant leak

I have noticed coolant spots on the floor of the garage under the passenger side of the engine. I replaced the water tube near the radiator last fall and did not see any spotting under recently. There is not any indication of leaks near the tube or hoses near the radiator. The only thing directly above the spots is the AC compressor. The overflow jug is farther back and to the left of the area, so where could it be coming from?

If the leak is too small to find with a pressure test, consider adding a small bottle of dark purple dye to the reservoir. After driving a few days you search with a black light. The dye will show up as a bright yellow stain that you can follow back to the source of the leak.
