Antifreeze leak

I have notice a antifreeze leaking through the weep hole on the{ water pump?}

could it be a bad water pump or somethijg else?? before I call American diesel thanks

Assuming Lehman 120? Then I would say the seal is leaking and you need a new coolant circulation pump.
I replaced mine once, not difficult to do, but you have to drain all the antifreeze out.
If it's been more than a few years since the coolant has been changed then it's due anyway. Also might as well put on a new belt.

Time for a pump. You may be able to have the takeoff rebuilt, call Depco and ask, they'll likely be able to tell you without having the pump in hand if it's rebuildable or cost effective. Then you'll have a ready spare.

That hole is put there to let you know the seal ( and possibly the bearing )is going bad.

This is the correct answer.
