Research on Catalytic Converter for Mercury Grand Marquis

A catalytic converter in a Mercury Grand Marquis is a device located inside the exhaust system. Its responsibility is to convert pollutant gasses being produced by your car into less harmful gasses. The bad gasses produced by our cars are hydrocarbons, carbon monoxide, and nitrogen oxides. The carbon monoxide is converted into carbon dioxide. The hydrocarbons are turned into carbon dioxide and water and the nitrogen oxides are turned back into nitrogen and oxygen. This is all done through your 1999 Mercury Grand Marquis catalytic converter by using the catalyst of platinum and palladium coated on a ceramic honeycomb inside a package in the exhaust.

Is The Cat Converter Necessary?

Is it necessary to have a catalytic converter and the o2 sensors or is it an option to have a pipe that runs straight with the muffler connected with just the sensors? One of the main purposes of a 95 Grand Marquis catalytic converter is to reduce emissions of these harmful gasses into the air we breathe. Every year or every other year, in most states, cars are required to pass an emissions test. One of the specific failing signs is that your 2004 Mercury Grand Marquis catalytic converter is not working properly and reducing the harmful gasses to a state-approved level. By law, in these states that require emission testing, you will need to replace your cat converter if you have Grand Marquis catalytic converter failure.

The Problem that Caused the Problem

A very common mistake made is to realize that you're having Mercury Grand Marquis catalytic converter problems and begin to investigate the price and the process for replacing it with a new one. The challenge here is that when catalytic converters go bad there is an underlying cause. Something else in your vehicle is not working properly and if you put a new catalytic converter for 2002 Mercury Grand Marquis on your car, it will fail too. The logical first step is to find out what caused the original cat converter to go bad and fix that problem. An overheating situation inside your 1998 Mercury Grand Marquis catalytic converter is often what damages it. The overheating problems can have a few origins but they all result in an improper air and fuel mixture that causes extreme temperatures and warp or melt the ceramic honeycomb device that converts the gasses. The main point is to fix the contributing problem initially.

The Cost of Clean Air

If you bring your car to a local repair shop to replace your 2001 Mercury Grand Marquis catalytic converter be ready for a shock. The price will range between $1000-$2350 and this doesn't include fixing any contributing problem that caused your catalytic converter to fail in the first place. If you can do the work yourself you will save some money. Another way to save money is to shop an online parts supplier like We can sell parts at a better price because we don't have a large overhead like the brick and mortar auto parts stores.
