I had the radiator replaced several times, recently new timing belt, new water pump and tune up. Headed out for Alaska and it over heated...Another new radiator and another overheating...Now I am told a new head gasket will take care of the problem. Could it be something more?
What causes the coolant in the tank to get foamy and bubble? on 1999 Subaru Legacy Outback
you could have a blown head gasket
Subaru has had a lot of problems with the head gaskets on the 2.5l. Make sure you have a shop that is experienced with Subaru's do the work.
very common for head gasket leaks on these , seek diag and est
