  Q: How to replace the intake manifold on Chevrolet Classic?

  A: To replace the Intake Manifold start by removing the air inlet duct as well as resonator, disconnect the iac (Idle Air Control) electrical connector, tps (Throttle Position Sensor) electrical connector, map (Manifold Absolute Pressure) sensor electrical connector, evap hose; pcv (Positive Crankcase Ventilation) hose purge solenoid, and the brake booster hose. Next, it is necessary to remove the oil indicator tube bolt, disengage the accelerator and cruise control cables from each other, as well as the Throttle Body and Fuel Rail. Remove the Knock Sensor connector from the Intake Manifold, disengage the nuts and bolts from the Intake Manifold, remove the Intake Manifold and you are left with the Intake Manifold. If needed, then remove the Intake Manifold Gasket which can be used if not damaged. For installation, if gasket was removed, install it first and slide the Intake Manifold back, then use nuts and bolts to fixed it with the torque of 10 nm (89 inch-lbs). Connect the Knock Sensor wire, fuel rail, and Throttle Body before the iac, tps, and MAP Sensor electric hookup and the former evap hose, pcv hose, purge solenoid tube, and brake booster hose. At long last, replace the oil level indicator tube bolt and bring the accelerator and cruise control cables into connection before fitting back the air inlet duct and resonator.
