The Intake Manifold replacement process necessitates initial pressure relief of the fuel system and subsequent removal of the air cleaner inlet duct , resonator assembly with bracket and
Fuel Rail cover. Begin by detaching the
Throttle Body vacuum lines followed by Throttle Body removal. After that you should disconnect the
MAP Sensor, remove the Fuel Rail then do the process in reverse. Use a hoist to elevate the vehicle then remove these components: evap purge solenoid, camshaft sensor, crankshaft sensor, vss,
Knock Sensor, back up lamp switch,
Oxygen Sensor and
Oil Pressure Switch. Follow these steps to remove the Intake Manifold from the engine: first lower the vehicle then unroute the wiring harness and finally remove the bolts and nuts securing the Intake Manifold. Before installing the Intake Manifold check the mating surfaces of the Cylinder Head and Intake Manifold for damage while also inspecting the manifold for surface damage and loose or broken flanges or cracks. For installation, place the Intake Manifold assembly onto the Cylinder Head, ensuring to tighten the nuts and bolts to 24 nm (17 ft. Lbs.) tighten the bolts to 12 nm while keeping the studs at 24 nm (107 inch lbs.). Sequnce the wiring harness before elevating the vehicle to reconnect the evap purge solenoid and its accompanying components including the camshaft sensor, crankshaft sensor, vss, knock sensor, back up lamp switch, oxygen sensor, and Oil Pressure Switch. The following steps must be taken: install the Fuel Rail, connect the MAP Sensor, install the Throttle Body, install the resonator bracket/fuel rail cover before placing the resonator and finishing with the air cleaner inlet duct.
