The replacement process for lh6, lmg, ly5 and l76 intake manifolds begins by removing the air cleaner outlet duct followed by removal of the generator. The engine harness retainer nut needs detachment followed by removal of the retainer from the stud and locator. First disconnect power cables from the evap canister purge solenoid followed by the
MAP Sensor and ignition coil harness and the left and right side
Fuel Injectors and throttle actuator and ect sensor. Secure all engine harness branches to the side and move them away from the work area. You should first move the Brake Booster Vacuum Hose aside and disconnect the evap canister purge tube and fuel feed line quick connect fittings when needed. After removing the Intake Manifold you should discard the old gaskets and use adhesive foil to protect the cylinder head openings from entry of debris. To replace the Intake Manifold pull off first the Brake Booster Vacuum Hose nipple followed by the upper Intake Manifold cover and MAP Sensor and
Throttle Body but discard the Throttle Body Gasket along with the Fuel Injector lower o-ring seals. Place new Intake Manifold gaskets while installing the Intake Manifold and apply sequence torque values to all bolts during installation. Reinstall all three components - the Brake Booster Vacuum Hose and fuel feed line and evap canister purge tube. Affix all engine harness connectors as well as retainer and clips while making sure each attachment point is secured. Reinstall the generator as well as the air cleaner outlet duct into position.
