Default Mid coolant leak

Hi got a 97 wrx . Just did a radiator swap as the the old one burst. I did a koyo rad install everything went great but on a drive I noticed I had started to leak towards the middle of my car a bit of coolant. It's somewhat near the oil pan . Have no clue where the leak could possibly be from as all the lines including the turbo one are tight and dry. Even did a thermostat replacement with gasket . Someone help!

You may just have coolant that you drained off and is on the metal work spraying off or it could be the oil cooler.
Between the engine and the oil filter is a oil cooler that has rubber pipes connecting it to the cooling system. These could be leaking and as it is in front of the sump the airflow could be pushing it around the sump.

As the aircon works cooling the air coming into the car any moisture condenses and then drains off under the car.

As above, plus the aircon has a drain line (item 12 below) that passes through the bulkhead to the left of the gearbox.
