GMC Yukon Catalytic Converters

A catalytic converter, also called a ‘cat’, is meant to convert harmful emissions such as Hydrocarbons and Carbon Monoxide into harmless ones: water and Carbon Dioxide. It is supposed to last the lifespan of a vehicle. But the sad truth is that it fails sooner or later due to natural wear and tear and gets clogged by contaminants from the coolant and various engine oil additives. Many problems with this exhaust part are caused by overheating due to engine issues such as misfires and rich air/fuel mixture due to bad spark plugs, a faulty oxygen sensor, etc.

Typically, a cat lasts approximately 10 years. When it is going bad, you will notice a number of signs that this part requires your attention. As an example, you may hear a rattling sound when idling or driving. If this component is clogged, it restricts the exhaust flow, and that may cause a decrease in fuel economy and acceleration. Obviously, it won’t perform its function properly resulting in excessive emissions, therefore a failed smog test. To keep your GMC Yukon legal to drive and operate at its fullest potential, you should replace its faulty cat.
