Pontiac Firebird Exhaust Manifold
The exhaust manifold of Pontiac Firebird vehicles focuses its hot exhaust gases from its cylinders into the rest of the exhaust system thus dictating high efficiency in the vehicles engine's performance. Suspended at different positions on one or many engine blocks, the manifold serves to eliminate intake reversion and to minimize back pressure which slows down the flow of air into the engine. The types found on Pontiac Firebird exhaust manifolds changed as time went on and it was normally made out of cast iron or sometimes stainless steel. There are other replacements referred to as headers meant for improvement of performance through minimizing of the resistance offered by the flow as well as rate of velocity provided for exhaust gases. These headers can enhance the efficiency of the engine through force induction scavenging of exhaust with pressures helping in evacuation of cylinders. In general, the design and material differences on the exhaust manifold of the Pontiac Firebird model bring about a change in the performance and emission quality the automobile possesses.

Pontiac Firebird Exhaust Manifold Parts Questions & Experts Answers
- Q: How do you properly remove and install an exhaust manifold in four cylinder engine on Pontiac Firebird?A: If the vehicle has air-conditioning, carefully examine the routing of the hoses and the mounting of the compressor, as it may be possible to remove the exhaust manifold without disconnecting the system; if uncertain, consult a GM dealer or automotive repair shop to have the system depressurized. Begin by removing the cable from the negative battery terminal, followed by the air cleaner assembly, tagging each disconnected hose with numbered tape for easier reinstallation. Next, remove the preheat tube, engine oil dipstick and dipstick tube, and the oxygen sensor. Label and disconnect the four spark plug wires, securing them to the side. Disconnect the exhaust pipe from the exhaust manifold, applying penetrating oil to corroded fastener threads if necessary, and hang the exhaust pipe from the frame with wire. Remove the exhaust manifold end bolts first, then the center bolts, and separate the manifold from the engine, followed by removing the exhaust manifold gasket. Before installing the new manifold, clean the gasket mating surfaces on the cylinder head and manifold, ensuring all leftover gasket material and carbon deposits are removed. Place a new exhaust manifold gasket on the cylinder head, position the manifold, and install the mounting bolts finger tight. Tighten the bolts gradually in the specified sequence until all are at the correct torque. Finally, reinstall the remaining components in reverse order, using new gaskets where applicable, and start the engine to check for exhaust leaks between the manifold and cylinder head as well as between the manifold and exhaust pipe.
