Pontiac Fiero Cylinder Head
The Pontiac Fiero Cylinder Head is the breathing gateway of the engine, sealing the combustion chambers while funneling the fresh air-fuel in and the hot exhaust out for smooth power. Mounted above the cylinders, the Cylinder Head is home to spark plugs, intake and exhaust passages, coolant routes, and the valvetrain. Any amount of warpage, cracked seats, or tired springs may cost you a cylinder in the form of burnt valves or lost compression. Over the years, engineers provided both sturdy cast iron and lighter aluminum Cylinder Head designs. The latter reduces mass for a better power-to-weight ratio and dissipates heat more quickly, which enables drivers to use a little more compression without fear of detonation. Both styles strengthen critical areas so that ports can be shaped to enhance airflow. As Fiero production progressed, these improvements became common. Reliable head gasket sealing requires torque to yield bolts that stretch once to provide even clamping and prevent the leaks that could mix oil and coolant, misfire, or trigger overheating. When symptoms such as coolant in oil or dead cylinders occur, inspection of the Cylinder Head and gasket is imperative. The second generation of Pontiac performance heads focused on smoother ports and stronger materials, but each Pontiac and each Fiero still relies on a sound Cylinder Head to ensure that combustion is sealed, the temperatures are controlled, and horsepower is flowing.

Easily un-bolt the exhaust manifold from the cylinder head and also take out the Intake Manifold. Remove the electrical connectors and the radiator hose at the left end of the cylinder head; and unbolt the ground strap at the right end. Remove the rocker arm cover assembly, then the rocker arms and push rods must be removed. With the new head gasket, reflect on the cylinders and also bolt pattern in cardboard to help in arrangement of the cylinder head bolts. Tighten the head bolts slightly and then unscrew them one by one and push them unto the cardboard you have arranged in a manner that corresponds with its installation order. Strike the cylinder head gently with a hammer and wooden block do not pry the head upward at all only push lightly at the overhang at the thermostat end, set the cylinder head on a wooden block to prevent it from being damaged.

Coat the threads of the retaining bolts and the undersides of the bolt heads with sealing compound, placing it in loosely so that no tightening is done at this stage. Engines with displacements of 1984cc and 1985cc should have the cylinder head bolt torqued in at least three steps in the sequence prescribed below. For 1986 and 1987 engines, gradually tighten the bolts in the sequence described to the initial torque number and then to the second number for all of the bolts except no 9 which should be tightened to the indicated torque number.
