2004 Chevrolet Silverado 3500 Exhaust Hanger Parts Questions & Experts Answers

• Q: How to replace the Exhaust Hanger Mounting Bracket on 6.0L, 6.6L, and 8.1L engines on 2004 Chevrolet Silverado 3500?

  A: The process of Exhaust Hanger mounting bracket replacement for 6.0l, 6.6l, and 8.1l engines requires initial removal of the exhaust manifold pipe along with the Catalytic Converter. The Exhaust Pipe hanger bracket bolts need removal on vehicles using a 4l60-e automatic transmission while vehicles using a combination of 6.0l engine and 4l80-e automatic transmission will require additional removal of these bolts. Vehicle owners must detach the transmission bolts along with Exhaust Pipe hanger bracket bolts in cases where their vehicle features a 6.0l engine paired with a 5-speed manual transmission. The Exhaust Pipe hanger bracket bolts need to be removed from 6.6l or 8.1l engines equipped with allison transmissions or 6-speed manual transmissions. The next operation involves reinstalling the exhaust manifold pipe bracket after removal. To install the Exhaust Pipe hanger bracket bolts on 6.6l or 8.1l engines with a 6-speed manual transmission fasten them to a torque of 12 nm (106 inch lbs.). Tighten all 6.6l or 8.1l allison transmission and 6.0l 5-speed manual transmission Exhaust Pipe hanger bracket bolts to 12 nm (106 inch lbs.). The Exhaust Pipe hanger bracket bolts of 6.0l engines with 4l80-e automatic transmissions should be installed and tightened to 12 nm (106 inch lbs.) and the procedure must be repeated for 6.0l engines with 4l80-e automatic transmissions. The Exhaust Pipe hanger bracket bolts must be installed onto vehicles with a 4l60-e automatic transmission before tightening them to 17 nm (13 ft. Lbs.). Reinstall both the Catalytic Converter and the exhaust manifold pipe as the last step.
