1995 Buick LeSabre Custom 6 Cyl 3.80L
Changed bad water pump. Now it leaks on backside of motor near the top. Is their a core plug back there?
There could be a freeze plug it is leaking from up there or possible a hose running along the backside headed to the heater core. follow the heater core hoses from the firewall and see if one goes to the back side of the motor.
