  Q: How to replace the catalytic converter on the right side for the 6.0L engine on GMC Savana 3500?

  A: In order to replace the Catalytic Converter on the right side of the 6.0l engine, start by raising the vehicle. Remove threads for the Oxygen Sensor connectors and unwrap the exhaust hanger locking left bolts and hanger from the car. Pull off the nuts that hold the Exhaust Pipe flange to the Catalytic Converter pipe, and loosen off the nut that holds the Exhaust Pipe clamp to the Muffler. Then, take out the Exhaust Pipe and flange gasket. For installation, the oxygen sensors additionally need to be pulled out and then insert the old ones into the new Exhaust Pipe. Screw them up tightly to 42 nm (31 lb ft). Next, install a new gasket to the Catalytic Converter pipe flange and then attach the Exhaust Pipe to the vehicle. Tighten the nuts on the Catalytic Converter pipe to the Exhaust Pipe unto 48 nm (35 lb ft) and tighten the Exhaust Pipe clamp nut unto 54 nm (40 lb ft). Check the exhaust system clearance and alignment of all parts, then fix the exhaust hanger and bolts, followed by pulling 17 nm (13 lb ft) before lifting the vehicles.

  Q: How to replace the front side door emblem/nameplate on GMC Savana 3500?

  A: To begin the process of changing the Savana Pro front side door emblem/nameplate start by applying tape across the area so you can protect and align it correctly. Set a heat gun (J 25070) with a distance of 152 mm (6.0 in) from the surface to warm the emblem/nameplate during a circular movement for 30 seconds. Melt the emblem/nameplate while being careful to minimize paint damage by using a plastic tool with a flat edge. Use 3M(TM) Scotch Brite Molding Adhesive Remover Disk (equivalent to 3M(TM) P/N 07501) to clean the door panel surface and the back of the emblem/nameplate. Clean the door surface through varnish makers and painters (VMP) naptha application. Use tape to mark the emblem/nameplate location when positioning the emblem/nameplate. Use the heat gun J 25070 to warm the door surface to 21°C (70°F) or higher but avoid letting it touch the adhesive strip of the emblem/nameplate. Position the front end of the emblem/nameplate over the door panel after removing the backing then press gently until you finish removing the backing. Follow hand rolling of the emblem/nameplate to ensure tight bonding and verify its connection and then eliminate the tape bordering the door emblem.

  Q: How to replace the camshaft on GMC Savana 3500?

  A: The radiator support must be removed first and then the valve lifters before starting the Camshaft replacement process. The next sequence includes eliminating the Timing Chain along with the Camshaft position actuator and the solenoid valve. First remove the Camshaft retainer bolts (204) and retainer (203) while paying attention to the Camshaft bearings because all Camshaft journals share the same diameter. Fix a bolt to the Camshaft for handling purposes before removing it from the engine block by rotating it gently. Thoroughly inspect the Camshaft together with its bearings while performing cleaning operations. A new Camshaft will require valve lifter replacement at the same time. Insert clean engine oil on all Camshaft journal bearings before beginning to reinstall the Camshaft through the engine block with the bolt as a guide. At the front of the Camshaft bolt must be removed while ensuring that the retainer has the sealing gasket facing the engine block along with a clean gasket surface. Use the Camshaft retainer part number 203 along with bolts 204 while securing the hardware using 25 nm (18 lb ft) of torque on first design hex head bolts and 15 nm (11 lb ft) on the second design torx(R) head bolts. The process should begin with reinstalling the Timing Chain then the Camshaft position actuator alongside solenoid valve followed by valve lifters and ending with the radiator support.
