Q: How to replace the intake manifold on 2000 Chevrolet Tahoe?
A: The first step involved in the replacement of the Intake Manifold would be disconnecting the battery negative cable as well as draining the engine coolant. Take off the engine sight shield and restore the accelerator control cable down with a hereditary one whenever the magnitude of the engine is removed, and locate the cruise control cable out of reach to avoid the damage due to physical activity. Now disconnect the accelerator control cable and the cruise control cable from the throttle shaft, then put them aside. Silently remove the engine sight shield mounting bracket and screws, the air cleaner duct, the inlet coolant hose, the vapor vent tube hose, and the exhaust gas recirculation (EGR) pipe bracket. Pull off large electrical harness retainer and withdraw one turn of m6 nut to remove the engine harness from the Intake Manifold. Pull off the eight fuel injector connectors, idle air control (IAC) motor, throttle position (TP) sensor, evaporative emission (EVAP) canister purge solenoid, and manifold absolute pressure (MAP) sensor, placing the electrical harness aside. Remove the purge solenoid vent tube from the solenoid, fuel pipes to the Fuel Rail, vacuum absorber brake booster hose if available, and the positive crankcase ventilation (PCV) valve and hose. Undertake the removal of Intake Manifold together with thorough cleaning and inspection of the same and the sealing surfaces. For installation, apply the Intake Manifold to the engine, reinstall the vacuum brake booster hose if needed, and also the PCV Valve and hose. Mount the fuel pipes to the Fuel Rail and the purge solenoid vent tube to the purge solenoid. Mount the engine electrical harness and nut and tighten the nut to 10 nm (89 inch lbs.) and run the harness over the engine and you will install the evap, tp, map, fuel pipes iac, and 8 fuel injector connectors. Reattach the engine sight shield mounting bracket and bolts and attach the accelerator control cable as well as the cruise control cable to the throttle shaft. Mount the engine sight shield, egr pipe bracket, vapor vent tube hose, coolant hose, and air cleaner duct. Finally, add coolant into the engine and connect the battery negative cable.
