2006 GMC Sierra 3500 Exhaust Hanger Parts and Q&A

• Q: How to replace the exhaust hanger mounting bracket for 6.0L, 6.6L, and 8.1L engines on 2006 GMC Sierra 3500?

  A: You should start your work to replace the Exhaust Hanger mounting bracket for 6.0l, 6.6l, and 8.1l engines by first removing the exhaust manifold pipe and the Catalytic Converter. The Exhaust Pipe hanger bracket bolts should be removed when working on vehicles equipped with 4l60-e automatic transmission. The removal process for 6.0l engine owners with 4l80-e automatic transmission requires them to take out Exhaust Pipe hanger bracket bolts. Vehicle operators should start by separating the transmission bolts and Exhaust Pipe hanger bracket bolts when the vehicle contains a 6.0l engine along with a 5-speed manual transmission. When working on 6.6l or 8.1l engines with either an allison transmission or a 6-speed manual transmission it is necessary to remove the Exhaust Pipe hanger bracket bolts. Reinstall the exhaust manifold pipe bracket once all its removal work is complete. Vehicle owners should install the Exhaust Pipe hanger bracket bolts on vehicles that have 6.6l or 8.1l engines with a 6-speed manual transmission using a torque of 12 nm (106 inch lbs.). When installing the Exhaust Pipe hanger bracket bolts to same specifications on allison transmission vehicles use identical torque values as instructed. To fit and bolt down an Exhaust Pipe hanger bracket at 12 nm (106 inch lbs.) for a 6.0l engine with a 5-speed manual transmission it is necessary to complete the installation by tightening transmission bolts to 100 nm (74 ft. Lbs.). The process for bolt installation requires a torque of 12 nm (106 inch lbs.) for the Exhaust Pipe hanger bracket bolts when using a 6.0l or 8.1l engine with 4l80-e automatic transmission. When installing the Exhaust Pipe hanger bracket bolts to a 6.0l engine with a 4l80-e automatic transmission use a torque of 12 nm (106 inch lbs.). Install the Exhaust Pipe hanger bracket bolts on a 4l60-e automatic transmission while applying torque to 17 nm or 13 ft. Lbs. Attach the exhaust manifold pipe along with its Catalytic Converter.
