My 1996 Blazer started to leak antifreeze. I thought it was the waterpump so I changed that. When I put antifreeze in the radiator it poured out right behind the waterpump. I checked all the bolt to see if they were tight and they are. Someone then said it might be the freeze plug. I was wandering where the freeze plug is located at on the motor.

Make sure that the water pump is installed properly.
Check the bleed hole, the seal may not be sitting well when you installed the new pump.

Did you also coat each bolts with gasket sealer? Very important step or you will get this kind of leak.
Frost plugs are on the side of the engine.
If you did not coat your bolts, take them out 1 at time, coat, let them get a little tacky and then install.
Goodluck
let us know what happens

Freeze plugs are on the engine block. I believe there is one near the pump but not behind it.
