If the head gasket fails, it can cause major problems in your engine that could be costly to repair. Here’s what you need to know about head gasket failure in a 2008 Subaru 2.5:

What is a Head Gasket?

A head gasket is a thin, durable material that sits between the engine block and cylinder head to ensure a proper seal. Its main job is to keep the coolant and oil passages separate, and also to provide a barrier between the combustion chamber and coolant passages. When the engine is running, the head gasket creates a seal where the cylinder head and engine block meet, allowing the engine to operate without any leaks.
