Evening all! I have a bx23mlb so basically a bx23d that in the last two weeks has begun leaking oil or coolant. In the attached photo you can see it is wet around the pulley that is seated behind the radiator. I took the radiator out last week and changed the fluid for what to my knowledge was the first time. I could not see anything that looked notably damaged. With it being the original coolant that is why I’m unsure if it’s oil or coolant since the coolant was very dark prior to draining. There is a slow drip when the tractor is off right behind the oil pan where there is a 45 degree ramp on the bottom of the frame. Think it is the water pump but not a hundred percent sure. Any ideas would be greatly appreciated
