GMC Sonoma Cylinder Head
The GMC Sonoma Cylinder Head helps control the flow of air, the sealing and heat so that the compact truck's workhorse engine can fire off perfectly and make rock-solid power. Sitting above the pistons, the Cylinder Head routes the fresh air-fuel mix in, channels exhaust out and holds spark plugs and valves in perfect alignment while coolant passages whisk away heat. Worn Cylinder Head guides, valves, seats or warped castings can allow combustion or coolant to leak out, resulting in misfires, leaks or overheating. Torque-to-yield head bolts are applied once then discarded to provide even clamping and keep the head gasket sealed tight. Two main constructions exist, a rugged cast-iron Cylinder Head with durability and an aluminum version with weight reduction, faster cooling and the ability to have higher compression without detonation. Performance versions of both have reinforced walls and reshaped ports to better the airflow. In every GMC, the right bolt stretch and gasket integrity is a defense against coolant in oil or lost compression. Sonoma owners know a good Cylinder Head is a reliability for daily driving or extra horsepower if modified to make the Sonoma a confident member of the GMC lineup.
Each OEM GMC Sonoma Cylinder Head we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
