Catalytic Converter Do’s & Don’ts:

Catalytic Converter Do’s & Don’ts:

Things to consider once your Catalytic Converter has been replaced with a new Zetti Emissions component.

• It is highly recommended that you use high octane fuel, for example 95 or 98 Octane and avoid Ethanol blended fuels. Ethanol blended fuels severely decrease Catalytic Converter efficiency & life span.

• If your vehicles Catalytic Converter was replaced due to an Check Engine Light issue, (usually the P0420 fault code) it is highly recommended that you also have further checks completed by your chosen mechanical workshop to ensure your vehicle does not have additional non-Catalytic Converter related faults.

• If you experience any further issues with the Check Engine Light illumination after replacement of a Catalytic Converter, please make your exhaust specialist aware immediately as continued driving of the vehicle may lead to further Catalytic Converter or other mechanical issues.

• Continuing to keep your vehicle properly maintained, for example replacing air and fuel filters and choosing the correct oil for your vehicle is also critical to Catalytic Converter efficiency and in turn life span.

 

Thank you for choosing a Zetti Emissions replacement part on your vehicle. If you have any further questions, please contact your exhaust specialist today.

Zetti means quality and that’s what we sell

Our Catalytic Converters are made to the highest quality standards and fit the first time, every time. Our range of European direct fit Catalytic Converters meet strict EURO emissions standards. This will ensure correct fitment and legal requirements are met all with minimal cost compared to factory items.

Made from the right stuff

palladium-rhodium-platinum

The use of precious metals is crucial to producing superior results and by combining Palladium, Rhodium and Platinum to form the composition of the substrate. These precious metals are fixed to the monolith via a Ceria based wash coat. All of the materials used are of high quality and have been tested to ensure product enhancement and ongoing range development.

How they compare

• 1.5mm stainless steel outer shell (opposed to 1.2mm found on others)

What is a Catalytic Converter and What to know when replacing.

What is a Catalytic Converter & How does it work?

Introduced to Australian motor vehicles in 1986, Catalytic Converters were fitted to unleaded petrol vehicles to clean up the noxious exhaust gases produced during operation. The role of the Catalytic Converter is to control the harmful emissions from the combustion process by converting the Hydrocarbons (HC), Nitrogen Oxides (NOx) and Carbon Monoxide (CO) into Carbon Dioxide (CO2), Nitrogen (N2) and Water Vapour (H2O).

The Catalytic Converter is designed to last the lifetime of the vehicle, but this is not always the case.** The premature failure of the Catalytic Converter could be attributed to poor tuning of the vehicles ignition, not servicing the vehicle at regular intervals, road impact damage, driving through deep water or using non-compatible fuels and additives. These conditions need to be avoided by the owner of the vehicle.

* Not all cats are designed with heat shields.
** Different materials used in the manufacturers construction process may attribute to shorter life span of the cat.

Replacing the Catalytic Converter… What you need to know.

1 – Ensure any engine or emission faults are rectified before replacing the catalytic converter. Failure to correct a pre-existing emissions problem could result in a damaged catalytic converter.

2 – It is recommended to replace the Oxygen Sensor when the Catalytic Converter is replaced. For correct operation of the engine and Catalytic Converter, the vehicle must be fitted with an Oxygen Sensor. When combustion gases are flowing through the exhaust, they are picked up by the Oxygen Sensor and a signal is sent back to the ECU. This signal then helps to control the air/fuel mixture entering the combustion chambers for a better ‘burn’.

3 – Always use new mountings, gaskets and bolts to avoid leakage or fitment issues. This will ensure the correct fitment first time around. Always recommend new studs, bolts and nuts when replacing any part of the exhaust system.

4 – When replacing a Catalytic Converter it is essential to examine the complete exhaust system from the manifold to the tail pipe for damage, corrosion or leaking/blowing. Repair or replace as required. A simple test is to have the vehicle running at idle whilst on the hoist. Use a shop rag to block the tailpipe (without burning your hand) and listen for any exhaust leaks in the system. Two people will be required for a closer inspection of any joins/pipes. The use of a vapour or smoke machine will accuarately locate any exhaust leaks.

5 – After replacing the cat converter be sure to run the vehicle at 2500rpm until the electric fans kick in. Then run the vehicle for a further 1 minute until the new catalytic converter temperature reaches 350˚C to ensure it is lighting off and functioning properly .

6 – Do not use exhaust sealant upstream of the Catalytic Converter. This can be a fatal move when working on the exhaust system. Sealants can contain ingredients that will harm the operation of the Catalytic Converter and also damage the Oxygen Sensor.
