How to replace the exhaust pipe on 6.01 and 8.1 engines on Chevrolet Avalanche 2500?

The replacement of exhaust manifold pipes on engines 6.01 and 8.1 begins with proper support of the vehicle during the work. After you remove the skid plate bolts of the oil pan and the plate itself, you should use a transmission jack to support the transmission. After removing the transmission mount to transmission support nuts, we should raise the transmission off its support component. Disassemble the bolts that hold the transmission support crossmember as well as the complete crossmember removal. First, remove any necessity of exhaust Muffler, then detach the engine harness clip with the Oxygen Sensor pigtail followed by disconnecting the connector position assurance (CPA) retainer and Oxygen Sensor electrical connector. The maintenance process requires Oxygen Sensor removal together with exhaust manifold pipe nuts and the pipe itself until the hanger slides from its bracket and disposal of the exhaust manifold pipe seal. Installation requires users to first position a fresh exhaust manifold pipe seal onto the exhaust manifold pipe followed by fitting the pipe while adding lubricant to the Exhaust Pipe hanger bracket for aid in installation. After placing the exhaust manifold pipe hanger within the bracket, you should install the exhaust manifold pipe nuts before torquing them to 50 nm (39 ft. lbs.). The replacement exhaust manifold pipe requires anti-seize compound GM P/N 12377953 or equivalent, which should be applied to threads of the old Oxygen Sensor before installing with a torque of 42 nm (31 ft. lbs.). The procedure for uninstalled pipes involves connecting the Oxygen Sensor electrical connector while also installing the CPA retainer and applying the clip over the engine harness and Oxygen Sensor pigtail. After installing the exhaust Muffler, you should reinstall the transmission support crossmember and bolts while torquing them to 70 nm (52 ft. lbs.). After lowering the transmission onto its support, you should mount the transmission mount at the transmission support nuts while applying 40 nm (30 ft. lbs.) torque. Replace the transmission jack while reinstalling the oil pan skid plate with its bolts to a torque of 20 nm (15 ft. lbs.). After that, lower the vehicle into position.
