Begin the new Intake Manifold installation by securing the evap solenoid isolator , solenoid , and bolt onto the manifold then torque the evap solenoid bolt to 10 nm (89 inch lbs.). Then install the accelerator control cable bracket and its corresponding bolts before tightening them to 10 nm (89 inch lbs.). Place
MAP Sensors before installing the
Throttle Body,
Fuel Rail, and injectors onto the new Intake Manifold. Apply new Intake Manifold gaskets onto the manifold before you set it into position. Apply a 5 mm (0.20 inch) band of threadlock gm p/n 12345382 or equivalent to the threads of the Intake Manifold bolts, then install and tighten the bolts in sequence to 5 nm (44 inch lbs.) for the first pass and 10 nm (89 inch lbs.) for the final pass. If available route the pcv hose with valve and the vacuum brake booster hose through the rear opening of the Intake Manifold. Set a new egr pipe gasket onto the exhaust manifold while you attach the egr pipe (with valve) using bolts securing it to the Intake Manifold , cylinder head , and exhaust manifold . Torque bolts to a firm state. Tighten the
EGR Valve pipe-to-Intake Manifold bolts to 10 nm (89 inch lbs.), the EGR Valve pipe-to-cylinder head bolts to 50 nm (37 ft. Lbs.)secure the egr pipe to exhaust manifold with bolts tightened to 30 nm (22 ft. Lbs.). Secure the electrical harness by directing it above the engine and attach the
Knock Sensor harness electrical connector to the Intake Manifold. Install the MAP Sensor and Knock Sensor electrical connectors into position. Connect the main ignition coil harness and the
Fuel Injectors alongside the EGR Valve connectors and finish with harness clips to the Fuel Rail. Repeat the connection for the main ignition coil harness and fuel injectors , then attach the wiring harness clips to the Fuel Rail. Install the accelerator control cable onto the bracket and throttle blade before connecting the cruise control cable bracket to the throttle blade stud. Finish by installing the engine sight shield and retainer.
