2000 Chevrolet Metro Parts Questions & Experts Answers

• Q: How to service and repair the intake manifold on 2000 Chevrolet Metro?

  A: The repair and servicing process for intake manifolds begins by removing fuel pressure followed by disconnecting the negative Battery Cable. Begin by draining engine coolant then removing the air cleaner assembly from the system. Service and repairs on the Intake Manifold start by disconnecting electrical wires from the engine coolant temperature (ECT) sensor and coolant temperature sending unit and throttle position (TP) sensor and exhaust gas recirculation solenoid vacuum valve and idle speed control (ISC) motor and ground wire bolts and throttle body fuel injection (TBI) unit and early fuel evaporation (EFE) heater if required as well as the release wiring harness from holding clamps. First disconnect the tbi unit's fuel return hose and fuel feed hose. Next disconnect the tbi unit coolant hoses (2, 3, and 4) and Intake Manifold hoses. The following components should be removed: egr modulator, egr valve and evaporative emissions (EVAP) canister vacuum hoses together with manifold absolute pressure sensor vacuum hoses and Brake Booster vacuum hoses. Preparation includes removing the positive crankcase ventilation (PCV) hose from the cylinder head cover and the accelerator cable from the tbi unit followed by five nuts and two bolts securing the Intake Manifold prior to completely removing the Intake Manifold , tbi unit , and wire clamps from the cylinder head while replacing the Intake Manifold Gasket . You must begin your installation process by placing a new Intake Manifold Gasket on the cylinder head before installing the Intake Manifold and tbi unit that needs wire clamps fastened using five nuts and two bolts tightened to 23 nm (17 ft. Lbs.). After securing the pcv hose ventilation hoses and coolant hoses (2,3,4) and fuel return and fuel feed conduits to their proper positioning on the tbi unit. Your installation requires connecting electrical wires between the ect sensor, coolant temperature sending unit, efe heater when necessary, ect switch, tp sensor, egr solenoid vacuum valve along with isc motor and Intake Manifold ground wires and the tbi unit electrical connector. Secure the wiring harness to retaining clamps before you install the accelerator cable onto the tbi unit and normalize its cable play according to specifications. After reinstalling the air cleaner assembly on the tbi unit along with reconnecting the negative Battery Cable you should refill the engine coolant before starting the engine to verify no fuel or engine coolant leaks occur at the Intake Manifold.
