Cylinder Heads & Parts

What Are Cylinder Heads and Why Are They Important?

Your vehicle’s engine is a perfectly tuned machine with thousands of components working in harmony to keep you heading down the road. One critical engine component is the cylinder head, which often includes various smaller components, such as valves, valve springs, pushrods, and more. These smaller components help regulate the mixture of air and fuel that create the internal combustion the engine needs to propel the vehicle.

Your engine requires a specific amount of compression during internal combustion to operate at peak efficiency. The cylinder head plays a critical role in this as it combines with the cylinder head gasket to create the seal at the top of each cylinder. If this gasket fails or the cylinder head becomes cracked or warped, your engine may lose compression, causing it to run poorly or not run at all.

Get Genuine Cylinder Heads and Parts at AutoNation Parts

If your vehicle’s cylinder head or related parts have failed or become damaged, you need to replace them to get it back into peak running condition. Fortunately, AutoNation Parts has you covered with a wide selection of genuine replacement cylinder heads and related parts that’ll get your engine back to running properly.
