View Here : What Year Did Subaru Fix Head Gasket
The head gasket forms a seal between the Subaru engine block and cylinder head. It is the most critical gasket in the engine and the most difficult to diagnose.
I have a 1997 Subaru Outback with about 280,000km on it. It began showing the head gasket failure symptoms so typical of the Subaru boxer 2.5L engine of this series of cars: foaming/bubbling in the coolant (the reservoir actually looked like a boiling kettle when the engine was running), brief random apparent spikes of the temperature gauge, and coolant loss.
The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.
A new purchase ’04 forester had the left side head gasket replaced at 44,000 miles in 03/2009 under warranty. The coolant reservoir started to foam at 70,294 miles 11/2010 Subaru dealer stated problem was a bad radiator cap.
