head gasket seaping anti freeze fluid. Is this a problem with a history ? Is it a alum head and should it be repaced or refaced before replacing gasket ? 58 K miles. Well cared for car.Under extended warrenty. 2th owner of car bought at 56K miles from dealer.

My recommendation is to follow the due process with your extended warranty. The repairs should be performed to the terms of this warranty with no issue.

you should resurface the head before replaceing the head gasket. alum tends to warped if over heated
