  Q: How to Replace a Throttle Body Assembly on Chevrolet K3500?

  A: In order to replace the Throttle Body assembly, first remove the intake air resonator and the air inlet duct from the Throttle Body. Remove the iac valve and tp sensor electrical connectors in addition to the accelerator and cruise control cables. Then remove the Throttle Body retaining nuts and pull out the Throttle Body assembly disposing of the flange gasket. Clean the surface of the Intake Manifold gasket before you bolt a new flange gasket and Throttle Body assembly. Mount the Throttle Body fitting nuts and tighten them to 25 n.m (18 lb ft). At this stage, you can reconnect the accelerator and cruise control cables as well as the iac valve and tp sensor electrical connectors. Lastly, replace the air inlet duct to the Throttle Body and the intake air resonator.

  Q: How should you inspect and diagnose the distributor cap and rotor for potential issues on Chevrolet K3500?

  A: Look for Distributor Cap defects including cracks and holes or carbon track formation between terminals. Acceptable symptoms include normal discoloration and white buildup at terminals along with yellowed rotor caps and dark deposits at the rotor segment. Only replace parts if driveability issues exist. Professional intervention for a new cap and rotor installation should occur only when driveability problems emerge. To test for carbon tracks move an ohmmeter lead to a cap terminal while using the other lead to probe all secondary terminals and the center carbon ball; move the first lead between each terminal in sequence until all secondary terminals receive inspection; change the cap if non-infinite readings appear during testing. The process calls for cap replacement when non-infinite readings materialize during the testing procedure. Inspect the terminals of the cap for extreme corrosion while cleaning away the built-up material and plan for a new cap when corrosion threatens the component's structural integrity. If the rotor segment shows substantial wear it should be replaced because of its significant looseness. Detect shaft bushing looseness by placing the shaft into the housing to check for movement. The housing assembly requires replacement whenever the shaft shows any type of wobbling motion. Check the housing for any signs of damage or cracks as the last step of inspection. To diagnose ignition systems on vehicles running 5.0/5.7l engines utilize enhanced software found in computers and control systems- 5.0, 5.7l while the diagnosis software for 7.4l engines runs on computers and control systems - 7.4l.

  Q: How to replace the upper intake manifold on Chevrolet K3500?

  A: To remove the upper Intake Manifold, the negative cable from the battery first needs to be disconnected. Take off the intake air resonator and the air cleaner inlet tube from the Throttle Body along with a crankcase ventilator tube and the PCV Valve from the valve rocker arm cover. Remove the egr pipe from the upper Intake Manifold and if equipped, left and right side secondary air injection pipe. Then you remove the Ignition Coil, throttle body, evap canister solenoid valve, and the number 8 spark plug wire from the Distributor. Then remove the upper Intake Manifold bolts, and remove it along with the gaskets. Remove carbon deposits in excess on exhaust and EGR Valve passages. For an installation, you should install the upper Intake Manifold, then, install the upper Intake Manifold gaskets. Apply a minimum of eight threads of thread locking sealant on bolts then install and tighten the upper Intake Manifold bolts in sequence to 8 nm (71 in. Lbs.) and re-tighten to 18 nm (13 ft. Lbs.). Replace the number 8 spark plugin wire, the Ignition Coil, and the EGR Valve if needed, then replace it with the egr pipe while tightening the EGR Valve fittings up to 60 nm (46 ft lbs). Please install the left and right side secondary air injection pipes if fit and the evap canister solenoid valve, throttle body, the PCV Valve, crankcase vent tube, and the air cleaner intake duct before installing the intake air resonator. Finally, reattach the negative tip of the battery, which will finish the procedure.

  Q: How to service and repair the front interior door handle on Chevrolet K3500?

  A: Starting the repair and service of the front door interior handle requires first removing the entire inside door handle assembly. The removal of inside door handle bracket from the door depends on drilling out the rivets with a 1/4 in drill bit. The Rivet Gun (J 34940) will secure the inside door handle bracket to the door using rivets before you reinstall both parts.
