How to replace the left catalytic converter on a 6.0L engine on GMC Savana 2500?

A properly fitted vehicle forms the starting point for left Catalytic Converter replacement on 6.0l engines. Disconnect the oxygen sensors before you remove the exhaust hanger bolts together with the hanger. Use pliers to unscrew the retaining nuts from the Exhaust Pipe connection to both the Catalytic Converter pipe and the Muffler before extracting the Exhaust Pipe and its flange gasket. To install the new Exhaust Pipe remove old oxygen sensors and insert them into the new pipe while tightening them to 42 nm (31 lb.ft.). When replacing exhaust components place new gaskets onto both Muffler flange and Catalytic Converter pipe flange before installing the Exhaust Pipe. Fix the Catalytic Converter pipe to the Exhaust Pipe through nut installation at 48 nm (35 lb ft) torque followed by Muffler fixation to Exhaust Pipe at the same torque. Complete the connection of Oxygen Sensor connectors and place the exhaust hanger and bolts through installation while tightening them to 17 nm (13 lb ft). Verify the exhaust system by checking for proper component alignment as well as clearance before completing the vehicle's lower-down process.

How to replace the catalytic converter on the right side for the 6.0L engine on GMC Savana 2500?

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.
