How to Replace a Catalytic Converter Safely and Effectively on GMC Yukon?

To replace the Catalytic Converter, first, begin with raising and supporting the vehicle. First, if present, remove the oil pan skid plate with the next step being to remove the transmission crossmember. If replacing three ways Catalytic Converter, remove heated oxygen (HO2S) sensors; otherwise, disconnect their harness connectors. Then, detach the nuts that connect the Catalytic Converter pipe (to the Exhaust Manifold and the Catalytic Converter to the Muffler) then pull out the Catalytic Converter pipe assembly from the vehicle, dispose the exhaust seals (2 and 3). For the installation, install new Exhaust Manifold seals (2 and 3) and attach the Catalytic Converter pipe to the exhaust manifolds. Fix the Catalytic Converter pipe on to the Exhaust Manifold nuts and firm them fully to 50 nm (37 lb. Ft.), then the Muffler with the Catalytic Converter nuts and tightening the clamp bolt fully to 45 nm (33 lb. Ft.). Reinstall the transmission crossmember. If the sensor is re-installed, then a special anti-seize compound, that is composed of the liquid graphite and glass beads, should be applied on the ho2s threads. If changing the three-way Catalytic Converter put on the heated oxygen (HO2S) sensors. Otherwise, connect the harness connectors. Lastly, install the oil pan skid plate if so equipped, lower the vehicle and check for exhaust leaks.

The Catalytic Converter in GMC Yukon automobiles is a vital part of the emission control system which changes toxic gases that are CO, HC, NOx and deposition them into less toxic products which include H2O, CO2, and Nitrogen. These converters have a honeycomb core and function via the use of catalysts such as platinum, palladium, and rhodium to initiate chemical reactions thus eliminating the emissions. Several reasons may cause converter failure and include engine related difficulties, impacts, or clogging hence leading a faulty converter with poor efficiency and high pollutant rates. GMC has powertrain converters that allow for maximum engine performance for different vehicles with available direct fit and universal converters. In general, Catalytic Converters provide significant contribution to minimize the emission of Harmful gases and maintain a standard for emission control in GMC Yukon vehicles.
