Research on Catalytic Converter for Buick Century

Designed solely for emissions and pollution reduction, a catalytic converter will cause more than air pollution if it fails. There are many reasons it can fail, from backfires that release combustible fuel into the honeycomb monolith to an exhaust leak. A bad cat will affect how your car rides. It can lead to engine trouble as well. Although not cheap to replace, the catalytic converter is extremely important; driving with a faulty on can lead to other expensive repairs.

Signs It's Time for Catalytic Converter Replacement

It's not just a failed emissions test, or noise, that will signal a cat problem in your Buick Century. Restricted exhaust flow from clogs and leaks from cracks can cause a reduction in power and acceleration. A rattling noise is also a common sign you need 2002 Buick Century catalytic converter replacement. If there is extensive internal damage, the catalyst-coated honeycomb can collapse or fall apart. The noise will get worse over time. It's also common to see the Check Engine light if the catalytic converter is failing. Even if the symptoms aren't obvious at first, a mechanic will conduct an emissions test and inspect the car to determine the root cause.

Structure of a Catalytic Converter

Each cat has an outer metal shell. Inside is a ceramic monolith core with a precious metal catalyst. This structure is often the cause of, for example, 2003 Buick Century catalytic converter problems. There are also oxygen storage promoters and a washcoat. The unit is placed such that it is directly in line with the exhaust, and is often just behind the exhaust manifold. Exposure to high temperature exhaust gases enables the oxidation and reduction reaction to take place. Nitrous oxides and other gases are converted to inert ones, including water vapor and carbon dioxide.

History of the Catalytic Converter

Long before your 2002 Buick Century catalytic converter problems, the device was in use. Research began in the 1950s to make cats for gasoline engines. They were developed much earlier than that to address pollution from smoke stacks in the United States. A French mechanical engineer, Eugene Houdry, was an expert in catalytic oil refining and led the development process, starting with catalytic converters for smoke stacks and then for unleaded gasoline warehouse forklifts.

Cost of Catalytic Converter Replacement

Your 2001 Buick Century catalytic converter problems can be resolved for $563 to a whopping $1,166. The expensive part a cat often is, it can be over $1,000 for a new component. If the 2001 Buick Century catalytic converter cost has you putting off repairs, start shopping around. You don't want to wait too long. At PartsGeek.com, it won't take long to find the part for your make, model, and year, and one at a reasonable price.
