Leaking anti freeze near water pump. on 2001 Chevrolet Express 3500

Appear to be leaking anti freeze near water pump. Most noticeable when i fill the overflow to the proper level. The next day a puddle appears on the ground. It stops for awhile then shows up again out of the blue. Any help will be appreciated.

Have a pressure test performed on the cooling system. It will expose any leaks pretty clearly. If needed, dye can be added to the coolant to pin point a leak's source.

Good luck!
