If you plug the weep hole on a water pump the water pump will stop leaking and can get you down the road in an emergency.

However the weep hole leaking on the water pump is a sign that the water pump seals are going out or have gone out and the water pump needs replaced.

I have had to plug the weep hole on the water pump before on my truck to get down the road when it started slightly leaking.

However I got a new water pump as soon as I got to a shop the same day and then replaced the water pump before I drove any further except to get home.

Water pumps start leaking out of the weep hole for a good purpose and they should never be plugged and you continue driving.

The weep hole leaking coolant on a vehicles water pump means the water pump is failing or has failed.
