  Q: How to replace the Exhaust Hanger Mounting Bracket on 6.0L, 6.6L, and 8.1L engines on Chevrolet Silverado 3500 Classic?

  A:

  Engineers should start the Exhaust Hanger mounting bracket replacement process for 6.0l, 6.6l, and 8.1l engines by taking off the exhaust manifold pipe and Catalytic Converter first. The hanger bracket bolts which support the Exhaust Pipe need to be removed from vehicles that operate with a 4l60-e transmission system. Car owners should delete the Exhaust Pipe hanger bracket bolts if their vehicle operates using either a 6.0l engine with a 4l80-e automatic transmission or it possesses both a 6.0l or 8.1l engine coupled with a 4l80-e automatic transmission. The installation process for vehicles with a 6.0l engine using 5-speed manual transmission requires you to start by removing first the transmission bolts before proceeding with Exhaust Pipe hanger bracket bolts. Vehicle owners with 6.6l or 8.1l engines alongside an allison transmission or 6-speed manual transmission need to remove Exhaust Pipe hanger bracket bolts. Install the exhaust manifold pipe bracket following its removal process. When the vehicle combines a 6.6l or 8.1l engine with a 6-speed manual transmission, you should attach Exhaust Pipe hanger bracket bolts which must be tightened to 12 nm (106 inch lbs.). The Exhaust Pipe hanger bracket bolts must be installed on 6.6l or 8.1l engines with allison transmission and 6.0l engines with 5-speed manual transmission and tightened to 12 nm (106 inch lbs.). The transmission bolts on 5-speed manual 6.0l engines need to be installed while ensuring a torque of 100 nm (74 ft. Lbs.). You need to install hanger bracket bolts on exhaust pipes between 6.0l or 8.1l engines coupled with 4l80-e automatic transmission systems while bolting them to 12 nm (106 inch lbs.). At each location on the Exhaust Pipe hanger bracket of 6.0l engines with a 4l80-e automatic transmission install the retaining bolts with a torque setting of 12 nm (106 inch lbs.). Install the Exhaust Pipe hanger bracket bolts into vehicles which use 4l60-e automatic transmission then follow up with a torque of 17 nm (13 ft. Lbs.). Reinstall the Catalytic Converter and the exhaust manifold pipe before completion.
