New to me X5 has a lot of fluid dropping from the driver's side front. It is watery with a very slight slick feel. I see what appears to me a drain hole in the under body plastic, so it must be normal?

Most cars I have had that drip from the A/C have dripped less moisture.
Puddle leaves about a 5" round water mark on the ground.
Thinking maybe coolant?

Also how do I check the coolant temp. in this car? No temp gauge,only a warning light?

Thanks.
