I have a 93 toy p/u with a 22r. I changed the water pump due to overheating and a leeking weep hole. One day later the new waterpump starts leeking from weep hole so I take it back thinking it was a defective pump. One day later that one starts leeking through the weep hole.does anyone know what might be happening?

 

you have bad luck? could a clogged radiator do this?

 

Radiator flow seems OK
