• Q: How to replace the intake manifold on 2005 GMC Savana 2500?

  A: First, you need to remove the Throttle Body, oil fill tube, and fuel injectors to replace your Intake Manifold. Remove the manifold absolute pressure (MAP) sensor and Knock Sensor electrical connectors and pull the Knock Sensor harness connector from the Intake Manifold and lay the electrical harness down. Then, take off the positive crankcase ventilation (PCV) hose together with the valve and MAP Sensor from the Intake Manifold. Remove accelerator control cable bracket bolts and the bracket and evaporative emission (EVAP) purge solenoid vent tube followed by detaching the evap pipe end from the solenoid, squeezing the evap pipe quick connect fitting retainer, and removal of evap pipe end from vapor pipe. Unbolt the evap purge solenoid bolt, solenoid , and isolator from the Intake Manifold and remove bolts from the intake and the manifold, uninstall the Intake Manifold Gasket, which should be thrown out. New Intake Manifold gaskets should directly be mounted to the Intake Manifold, after which the manifold is installed. Assemble a 5mm (0.20in) band of threadlock gm p/n# 12345382 (Canadian P/N# 10953489) or equivalent to the Intake Manifold bolts and install the nuts, and tighten them in sequence to 5mn (44 inch lbs) for the initial turn and final turn to 10mn (89inch lbs). Mount evap purge solenoid, isolator and bolt to Intake Manifold, tightening solenoid bolt down to 10 nm (89 inches lb.). Reinstall the evap purge solenoid vent tube onto the solenoid and vapor pipe and then install accelerator control cable bracket and its bolts tightened to 10 nm (89 inch lbs.). Apply a light coat of clean engine oil on the MAP Sensor seal and install a MAP Sensor onto the Intake Manifold followed by the pcv hose (with valve). You should connect the Knock Sensor harness electrical connector of the Intake Manifold and the electrical connectors of your MAP Sensor, knock sensor, and EGR Valve if available. Lastly, replace the fuel injectors as well as oil fill tube and the Throttle Body.
