Is it leaking externally? If so double check it's not coming from one of the head bolts. If someone had done prior maintenance and didn't use thread sealer on the heads bolts they will leak since they go into the water jacket.
Is leaking externally. Middle of head. So what you are saying Is I can just remove that bolt and put sealant on it and retorque the bolt? . Or is it a blown out head gasket.
