I'm looking into this Forrester that overheats.The thermostate has been changed and ran fine for part of the day.Went to head out of town and only got a few miles out of town and it overheated.I suspect a head gasket has failed.I would like assistance to determine which side is the culprit.Would it be just wise to change both sides??I'm also looking to find info on the repair proceedure.I would appreciate any help.The vehicle has a 2.4 litre motor with standard tranny.
