Replace Catalytic Converter in Minneapolis

What Are Common Catalytic Converter Problems?

Catalytic converters are located in the exhaust system between the engine and the muffler, and they are one of the last lines of defense against air pollution from vehicles. They use ceramic-coded beads and various precious metals (the catalysts) to convert pollutants like unburned gas and nitrogen oxide into harmless gases.

What Are Potential Issues With a Catalytic Converter?

Catalytic converters often last for 10 years or more, but they can become contaminated, clogged, overheated or physically damaged — leading to sluggish engine performance and, eventually, engine shutdown.

One potential contaminant is leaded gas, which can destroy the catalysts, although it is rarely found in the U.S. Others contaminants include engine coolant, which can leak into the combustion system because of a faulty cylinder head gasket, and engine oil. Those fluids can clog a catalytic converter so that exhaust gases are restricted from passing through. Car engines are like athletes in that they require lots of oxygen. If the exhaust flow is restricted, it means less air can get into the engine and performance suffers. If the engine responds sluggishly or quits after running for a while, a clogged converter could be to blame.
