How to replace the upper intake manifold on Chevrolet Impala?

Replacement of the upper Intake Manifold requires the battery ground cable and Throttle Body iat sensor wiring harness attachment to be detached first. Start by disconnecting the Throttle Body air inlet duct and proceed to drain engine coolant from your vehicle's cooling system. Disassemble the accelerator control cable with the cruise control bracket from the Throttle Body and proceed by removing the Throttle Body itself. First disconnect the wiring harness attachment clips that serve the Camshaft Position Sensor and left spark plug wire harness and then remove the thermostat bypass pipe coolant hoses that connect to the Throttle Body. Disassemble the rear generator brace while you eliminate these subsequent components: the maintenance process includes removing vacuum lines from three separate components: upper Intake Manifold, map sensor, egr valve, followed by disconnecting Spark Plug Wires and igniting control modules and removing the upper Intake Manifold before replacing its gaskets and vacuum lines. Prior to adding Throttle Body and upper Intake Manifold gaskets you should clean all manifold seal surfaces with degreaser. Use threadlock gm p/n 12345382 or equivalent on the Intake Manifold bolts followed by upper Intake Manifold installation and torque upper Intake Manifold bolts to 25 nm (18 lb ft). The installation sequence includes upper Intake Manifold gaskets followed by the upper Intake Manifold and Ignition Control Module and then Spark Plug Wires and EGR Valve and MAP Sensor and vacuum lines for the upper Intake Manifold. Installation should begin with the rear generator brace followed by connecting thermostat bypass pipe coolant hoses to the Throttle Body. Wire harness connectors need to connect to throttle position (TP) sensor and idle air control (IAC) valve locations on the Throttle Body. After filling the cooling system with engine coolant, install the Throttle Body air inlet duct and carefully connect wiring harness connectors to the intake air temperature sensor within the duct and the vacuum hose to it. Finally, reinstall the negative Battery Cable.

The Intake Manifold of Chevrolet Impala cars plays the very important function of delivering the air-fuel mixture in the engine cylinders uniformly for better efficiency and performance. Screwed to the cylinder head it smooths the air supply while harboring temperature, airflow, and pressure sensors which optimizes the functionality of engines. Throughout the years, there have been several types of Intake Manifold designs we have used on Chevrolet Impala that range from the basic aluminum or cast iron in the older models and advanced composites plastics in the newer models. Juxtaposing, recent innovations in the intake manifolds include the variable-length intake manifolds (VLIM), which enables the power, torque, and even the fuel economy to be advanced due to the variation in the intake tracts in relation to the load conditions in the engine. Problems like the failure of intake manifold gaskets could really affect the performance especially in the recent Chevrolet Impala models, therefore it is crucial to maintain this component for the good health of the engine.
