Research on Catalytic Converter for Buick LeSabre

The Buick LeSabre is GM car that has been on the market since 1950's. It is considered as being a full-size car, and it is the cheapest in the Buick line. It is important to appreciate how eco-friendly this car is, thanks to its catalytic converter. Most car owners are not aware of much of what the catalytic converter means to the car.

What is a catalytic converter?

This is a device that converts harmful compounds which include hydrocarbons, nitrogen oxides and carbon monoxide in the car exhaust and turn them into harmless compounds. Looking at the pollutants, carbon monoxide is dangerous when it is inhaled, nitrogen dioxide, on the other hand, is the primary cause of acid rain of what is also commonly known as smog.; hydrocarbons produces smog too. When the compounds get into the catalytic converter, the catalyst is placed in ceramic beads that are packaged in a muffler package that is attached next to the exhaust. The catalyst then helps the conversion of the carbon monoxide to carbon dioxide. Hydrocarbons are converted into water and carbon dioxide. Finally, the nitrogen oxides are converted back to oxygen and nitrogen.

The catalytic converters need a high temperature around 800 degrees to convert the harmful gasses to the less harmful states. There are cases when there has been an unwanted reaction in the converters. There have been formations of ammonia and hydrogen sulfide. It is not easy to eliminate these byproducts.

How to install the catalytic converter.

In the Buick LeSabre, the catalytic converter is essentially placed like in other cars, right under the engine's exhaust manifold. Due to the high temperatures, the converter usually heats up very fast. Burning off excess hydrocarbons reduces emissions during the warm-up period of the engine. When it was introduced in the market, catalytic reactions did not occur efficiently due to the use of carburetors that provided relatively low air-fuel. A secondary air injection, to supply air to the exhaust stream, had to be included in most of the designs. A controlled air-fuel mixture is provided, which continually cycles between rich and lean combustion, this is due to the new electronic fuel injection systems most vehicles have. To monitor the exhaust's oxygen content before and after the catalytic converter, oxygen sensors are used. It is also important to note that lead is a contaminant to the catalytic converter. Therefore, vehicles that have the converters installed only rely on unleaded fuel.

Buick LeSabre Catalytic Converter Cost

A Buick LeSabre Catalytic Converter replacement averagely costs between $507 and $1167. The labor costs involved usually range between $96 and $123 while the parts are priced between $411 and $1044.

Seems to be what my mechanic wanted; arrived about a week after the order was placed, in good shape; the only installation issue was that he needed to order, separately, the rectangular gasket for that one end, which he got from the local parts store (if it was supposed to be included, it wasn't)--but that wasn't much of a snag. Now the question is whether the "CHECK ENGINE SOON" light will STAY out--and I won't know that for another two weeks or so. Supposedly, though, there is a reasonable warranty on the unit from the manufacturer. - So far, so good
