The head gasket is a crucial component of your GMC Sierra's engine. It ensures that motor oil and coolant stay separated and creates enough pressure to keep your pistons firing properly. A blown head gasket results in decreased performance and fuel efficiency, and more serious engine damage. AutoZone offers Sierra head gasket sets to keep your truck performing.
