  Q: How to Replace an Interior Front Door Handle on GMC Sonoma?

  A: A person must first uninstall the door trim panel when replacing the front door interior handle. First remove the handle retaining bolt while sliding the handle forward until the handle locator tab frees from its cutout. Start by unlocking the rod retainer locks and extracting the rods from the handle until you can take out the handle from the door. Position the handle on the door before installing the rods to the handle and finally tightening the rod retainer locks. After placing the handle locator tab into the locator cutout you should move the handle toward the rear until the fastener hole properly lines up with the door. Reinstall the door trim panel after inserting the handle retaining bolt which must be tightened to 10 N.m (88 lb in).
• Oxygen Sensor

  Q: How to replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 on GMC Sonoma?

  A: You need to lift the vehicle before proceeding with HO2S Bank 1 Sensor 2 replacement. Remove the connector that connects to the HO2S. The HO2S should be removed using the Oxygen Sensor Wrench (J 39194-B). The new oxygen sensor threads must receive a coating of anti-seize compound GM P/N 5613695 followed by its installation. GM P/N 5613695 contains both liquid graphite and glass beads to make removal easier. The HO2S requires installation using the Oxygen Sensor Wrench (J 39194-B) until it reaches a torque value of 42 N.m (31 lb ft). Lastly connect the HO2S harness connector while lowering the vehicle.
• Intake Manifold

  Q: How to replace the lower intake manifold on GMC Sonoma?

  A: First dis-connect the neg. Battery cable and the breather tube at air cleaner outlet duct.then remove the air cleaner outlet duct to replace the lower Intake Manifold. Defeat the accelerator cable from the Throttle Body and keep it away from accelerator control cable bracket and followed by defeating the cruise control cable from throttle shaft and accelerator cable as well, if there's one. Remove the vacuum hose at the Intake Manifold if a/c is equipped, the power Brake Booster Vacuum Hose, and drain the cooling system. Disconnect the radiator inlet hose, hose leading to heater, and water pump inlet hose from the Intake Manifold. Cease the electrical connectors for fuel meter body assembly , evap canister purge solenoid valve,mapview sensor (MAP), ignition coil, ignition control module (ICM),generator, idle air control ( IAC ) motor, throttle position ( TP ) sensor, a/c compressor cutoff switch, a/c clutch switch, and engine coolant temperature ( ECT ) sensor. Cease the engine wiring harness clips and move the harness away and remove the accelerator cable bracket from the Throttle Body and Intake Manifold whiles keeping the cables connected. The pcv hose assembly must be removed from the Intake Manifold and valve rocker-arm cover, the evap canister purge solenoid valve and the Distributor. Remove the fuel supply and return hoses at the back of the Intake Manifold while avoiding the release of the refrigerant. To get access for left front bolt to the Intake Manifold, remove the Drive Belt, loosen and remove the power steering pump rear bracket nuts, and slide the power steering pump bracket front. Unplug the ect sensor wire connector, if available, and then unbolt the lower Intake Manifold bolts and Intake Manifold assembly, and dispose of the lower Intake Manifold gaskets. Clean the lower Intake Manifold with the cleaning solvent and dry it by compressed air checking on gasket sealing surfaces for damage or restricted cooling passages, cracks or damage to threading bolt holes. If a replacement was needed, use gm 4.0 mm (0.157 inch) patch of adhesive gm p/n 12346141 (Canadian P/N 10953433) or equivalent to the side of the Cylinder Head of the lower Intake Manifold gasket on each side, must be installed while the adhesive is still wet. Mount the lower Intake Manifold gasket on Cylinder Head using the gasket locator pins; apply a 5mm (0.197 inch) bead of adhesive gm p/n 12346141 (Canadian P/N 10953433) to the front and rear top of the engine block with bead running onto each lower Intake Manifold gasket. Mount the lower Intake Manifold on to the engine block and if bolts are re-used use thread lock gm p/n 12345382 (Canadian P/N 10953433) on the bolt heads, then tighten the bolts according to a predetermined sequence in a three-step sequence up to the specified torque values. Mount and loosely install power steering pump mounting bracket and tighten bolts and nuts at 41 nm (30 ft.blbs) and reinstall Drive Belt. Install the supply and return pipes of fuel while ensuring that the engine is at number one cylinder top dead center for fixing the Distributor. Remove the Spark Plug from the number one cylinder, turn Crankshaft to stop on the compression stroke, align the marks of reference, and re-install the Spark Plug and the Distributor. Replace the evap canister purge solenoid valve, pcv hose assembly, accelerator and cruise control cable bracket, tightening the nuts to specified torque values. Mount the engine wiring harness, attach the clips, and attach necessary electrical connectors. Attach the vacuum hose to the power brake booster, vacuum hose to the Intake Manifold if you have an a/c, and reinstall the water pump inlet hose, heater hose, and radiator inlet hose. If the vehicle comes with a cruise control cable, reinstall this particular cable, and then reinstall a cable that controls the accelerator on the Throttle Body making sure it is seated well, and attach the accelerator cable to the control bracket. Lastly, replace the air cleaner outlet duct, reconnect the breather tube, refill the cooling system, and reconnect the negative Battery Cable.
• Throttle Body

  Q: How to replace the throttle body assembly on GMC Sonoma?

  A: In order to replace the Throttle Body assembly, the mechanic has to disconnect the negative Battery Cable, remove the air cleaner outlet duct, and the air cleaner adapter stud. Release the cruise control cable and the accelerator cable from the Throttle Body and remove the nuts to hold the accelerator cable routing bracket which will be set aside. Next, you remove the stud and nuts holding the accelerator control cable bracket in place and take it off as well. Remove the iac valve harness connector and the throttle position (TP) sensor harness connector and then the Throttle Body was removed from their retaining studs and the Throttle Body itself was discarded along with the Throttle Body seal. Clean the surface of the Intake Manifold's seal and fit the Throttle Body assembly with new seal, holding it in place tightly with the retaining studs at 9 n.m (80 lb in). Insert and tighten the mounting stud and nuts to 12 n.m (106 lb in) and accelerator cable routing bracket nuts to 9 n.m (80 lb in). Check the full range of accelerator pedal movement to ensure the throttle runs freely without binding. Fit the accelerator cable and cruise control cable to the Throttle Body, and fit the tp sensor and iac valve harness connectors. Replace the air cleaner adapter stud with an 8 n.m (71 lb in) torque and the outlet duct of the air cleaner. Lastly, test the accelerator pedal operation by turning on the key with the engine out enabling a scan tool to check the tp sensor parameter and checking the movement of the throttle position from 0-100 percent and back to 0 percent.
