Pontiac Fiero Intake Manifold
Intake Manifold is one of the vital components of Pontiac Fiero vehicle which is responsible for delivering the air or air/fuel mixture to the individual cylinder affecting the power and performance of the engines. Different models of Pontiac Fiero have employed several types of intake manifold mostly for carbureted engines, Throttle Body Injection (TBI) and multi port fuel injection systems. Over the years these manifolds have gradually been developed with current manifolds commonly being made of lighter weight composite plastics instead of the cast iron or aluminum manifolds in the past that offer improved fuel efficiency, cooling. Also, some of the intake manifolds that are standard in Pontiac Fiero vehicles have been found to be variable length, it can change according to the load condition of the engine to give a perfect airflow thus increasing torque and fuel efficiency. Purge of the manifold leakage as well as the proper control of airflow over the runners' length are critical issues because any leakage and turbulence decrease efficiency.
Each OEM Pontiac Fiero Intake Manifold 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.
Pontiac Fiero Intake Manifold Parts Questions & Experts Answers
- Q: How to remove and reinstall the components of the intake manifold in four cylinder engine on Pontiac Fiero?A: To remove the components, first disconnect the cable from the negative battery terminal and remove the air cleaner assembly, tagging each hose with numbered or colored tape for easier installation. Relieve the fuel pressure and drain the cooling system. Remove the PCV valve and hose at the throttle body housing, then label and disconnect the fuel line fittings at the throttle body, removing the fuel filter bracket bolt underneath. Label and disconnect the vacuum lines and electrical leads from the fuel injection assembly. Disconnect the throttle cable from the throttle linkage by prying off the C-clip and popping off the linkage rod, noting its installation. If equipped with an automatic transmission, disconnect and remove the transaxle downshift linkage, and if cruise control is present, disconnect the linkage. Disconnect the heater hose fitting located on the underside of the intake manifold. Remove the forward strut rod through-bolt adjacent to the Cylinder Head, then remove the access plate in the top of the right fender well to access and remove the rear through-bolt, followed by the strut rod. Disconnect the alternator by removing the belt tensioning nut and bolt, then remove the alternator bracket. Disconnect the coil mounting nuts, coil lead, and coil wire, then remove the coil. Remove the intake manifold mounting bolts and separate the manifold from the cylinder head without prying to avoid damaging the gasket sealing surfaces. Remove the intake manifold gasket with a gasket scraper, ensuring no material remains on the mating surface. For installation, if replacing the intake manifold, transfer all components from the old manifold to the new one. Clean the cylinder head and manifold gasket surfaces, ensuring all gasket material and sealing compound are removed. Place a new intake manifold gasket on the manifold, hold it against the cylinder head, and install the mounting bolts finger tight. Tighten the mounting bolts gradually in the proper sequence to the specified torque, then push the electrical connectors back through the intake manifold. Install the alternator bracket, adjust the alternator belt tension, and install the strut rod with both through-bolts, tightening them to the specified torque before replacing the fender well through-bolt access plate. Place the TBI linkage rod into position and reattach the throttle cable, then reattach the heater hose fitting to the underside of the intake manifold. Reconnect the fuel feed and return lines, installing the fuel filter bracket mounting bolt, and reattach the PCV valve, elbow, and hose between the rocker arm cover and the TBI housing. Reattach the remaining vacuum lines and electrical connectors, install the coil assembly, and reconnect the coil lead and coil wire. Finally, install the air cleaner, fill the radiator with coolant, start the engine, and check for leaks.
