The Pontiac Grand Prix Cylinder Head controls the in and out of air fuel mixture to the combustion chambers to breathe efficiently and maintain compression. This allows the engine to breathe out efficiently and provide reliable power. Sitting on top of the cylinders, the Cylinder Head creates the roof of each cylinder chamber and contains the spark plugs and other important valves. It is sealed to the block by a head gasket to prevent coolant, oil, or combustion leaks. When that gasket fails, drivers can experience misfires due to lost compression, overheating due to coolant escape, or contaminated oil due to passages mixing. These are just some of the ways the Cylinder Head needs to clamp down tightly. To accomplish this clamp, modern engines employ torque to yield head bolts, which are single-use fasteners that stretch to a precise amount, distributing force evenly throughout the Cylinder Head and helping to improve the life of the gaskets. Across decades of Pontiac production, iron castings offered durability, but later models made of aluminum reduced weight, released heat quicker, and permitted higher compression. Today, the Grand Prix owner gets sharper response and superior weight balance when the lighter Cylinder Head replaces the older iron style. The expensive consequences of warped surfaces are avoided by regularly inspecting a Pontiac head for guide wear, burnt valves, or cracks. A well-sealed Grand Prix engine also ensures proper coolant temperature and oil purity, which adds to a long drivetrain life.
