2002 ML 320 Km 186 000.00
Water does not appear to be leaking from above the pulley, but dripping from bottom end of the water pulley.
Question please:
Does the ML 320 water pump have a wear hole in the above location?

If there is no wear hole, is this location [bearing] where water leaks out of the pump when it is on its way out?

Appears to be leaking when vehicle engine is turned off, "approximate" time until the pump goes completely? assuming the above is correct and it has a wear hole?

Please and thank you!
