For the left cylinder head, remove alternator with its bracket and detach ground strap from back of cylinder head. For right cylinder head take off dipstick tube and disconnect ground cables from front of cylinder head. Loosen the head bolts gradually in reverse order of tightening sequence until they can be removed by hand. Carefully remove the head(s) from the engine so as to prevent damage to mating surfaces.

If necessary chase thread holes in block with a tap or brake cleaner followed by compressed air then replace all head bolts with new ones. Place new gaskets onto dowels in block before placing heads on top without interfering with position of gaskets then tighten head bolts to specified torque in recommended sequence using specified tools. Finally install coolant pipe using new gaskets; proceed to reverse removal steps thereafter; add coolant; change oil and filter; start engine & check for proper operation/leaks.

GMC Yukon Cylinder Head

The GMC Yukon Cylinder Head seals the top of the combustion chambers, allowing the fresh air fuel mixture in and hot exhaust gases out to keep the power strong and the operation smooth. Over the years, GMC has fitted the Yukon with two kinds of Cylinder Head designs. This has been a traditional cast iron design and a lighter aluminum design to cut weight. The newer aluminum design sheds heat quicker due to the lower mass. Also, the reduction of weight allows a higher compression without detonation risk. All Cylinder Head, regardless of material, rely on evenly clamped multi-layer gaskets held by torque to yield bolts that stretch to their limit to prevent any form of coolant, oil, or combustion leaks that might trigger misfires, overheating, or messy cross-contamination of fluids. Common wear such as burnt valves, warped Cylinder Head surfaces, or tired valve springs can rob a cylinder of compression. Thus, the precisely machined guides, seats, and ports of the head are heavily reinforced in critical areas to ensure high airflow and dependable horsepower for use in day-to-day driving or towing. In earlier times, side valve layouts employed a basic flat plate. Presently, overhead valve and overhead cam layouts incorporate passages, injectors, and valvetrain hardware into one compact Cylinder Head. This updated setup provides for a quieter, more efficient performance that loyal Yukon drivers and GMC fans will appreciate.

Each OEM GMC Yukon 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.
