Catalytic Converter Important Information All Car Owners Should Know!

Catalytic Converters

Your catalytic converter may have failed or is starting to fail if you…

  • Have a minor or major loss of power
  • See a check engine light
  • Are starting to experience poor gas mileage
  • Smell any funny smells like "sulphur" (rotten eggs)
  • Hear any rattling or clunking sounds from under the car
  • See a white powder like substance in the end of the tail pipe
  • Have failed smog due to high HC or CO
  • Have hit something on the road causing internal damage to the catalytic converter

Note: Just because your vehicle passes a smog test does not mean that the catalytic converter is good! It just means that it was running good enough at the time to pass the test. If you notice any of these things you should have it checked immediately! Waiting may cause catastrophic engine failure meaning you will need a new engine and a new catalytic converter.

Federal Law says that your dealer must replace the catalytic converter if it has failed in less than eight years or 80,000miles
(for vehicles beginning with the 1996 model year)

If you're catalytic converter has failed then your car most likely has other problems that lead to the failure!

Protect the investment you are about to make by fixing the whole problem. Finding out what damaged your old catalytic converter will save you time and money. We can give your car a quick check-up to find certain components that may have failed causing your old catalytic converter to be ruined.

In this day and age vehicle manufactures are making cars very complex and difficult to work on especially if you do not have the proper tools, equipment, documentation, training and experience! There is an upside to some of this technology and that is vehicles made after 10/95 are so smart that they have the ability to monitor things such as air-fuel ratio and record this in the on board computer so a technician can see this information and make a determination on what is not functioning correctly. This is part of what is called the OBD II system, every car in the United States after 10/95 is OBD II certified. To see if your car is look under the hood on the emission label it will say somewhere on the label depending on the make.

Even if your car is not OBDII there are many things that can fail or slowly diminish like O2 sensors causing your catalytic converter to fail. It is important to have your car checked once a year or to do your recommended maintenance as the manufacture states in your owner's manual. Some times very small things like manifold leaks can be caught well before damage is done and it only takes a couple of minuets for us to check this.

The days of changing spark plugs, cap, rotor and tweaking the carburetor as a tune up are gone!

Nothing these days has a carburetor and many engines do not even have a distributor anymore. Keep in mind the basic principles of an internal combustion engine are the same (i.e. fuel, compression, spark) it is just the way that each of these is achieved is different and much more efficient than it use to be. Everything that controls air, fuel and spark are some how connected to on board computer through an-array of sensors, switches and solenoids etc.

Good automotive repair facilities spend a great deal of money per year to stay up-dated on equipment and training technicians. This is important for today and the future so we can find and fix the actual problem in the vehicle and not waste your money and time just throwing un-needed parts in to see what happens.

Trying to diagnoses the problem yourself or having a buddy or neighbor that "use to be a mechanic" help you out to save a few bucks will in most cases only cost you more money and down time in the long run. Things change so fast in this industry leave it up to the people that deal with these kinds of problems on a daily basis.

Installing a new catalytic converter is simple as long as you obey the law.

Choosing the correct replacement converter should be left to the professionals. That is where we come in.

There are several things that must be taken into consideration when selecting a replacement. The replacement catalytic converter must be properly selected by the specific engine family and cubic inch displacement of your vehicle. The replacement must have the required certification not just Federal law but must be certified in California as well!

The California Air Resource Board, Bureau of automotive repair and the Environmental Protection Agency strictly enforce rules and regulations on catalytic converter manufactures and installers to ensure that the correct part is installed on your vehicle. This is important, as your vehicle must have the proper catalytic converter that is sized and rated appropriately to last as long or longer than the original as well as protect our environment - something we all need.

Any failure to comply with laws regarding the installation of catalytic converters falls under a federal offense. The potential fines and penalties for removing or altering this vital piece of equipment are not worth the risk.
