For states requiring stricter emissions standards, such as California, Colorado, and New York, Walker also offers CARB-compliant converters. Users should verify the specific compliance requirements for their region.
Manutenzjoni
Catalytic converters generally do not require specific routine maintenance. Their longevity is primarily dependent on the overall health of the vehicle's engine and exhaust system. To ensure optimal performance and lifespan of your catalytic converter, adhere to the following general vehicle maintenance practices:
- Perform regular engine tune-ups as recommended by your vehicle manufacturer.
- Address any engine misfires, excessive oil consumption, or coolant leaks promptly, as these can damage the converter.
- Ensure oxygen sensors are functioning correctly, as they play a vital role in monitoring and optimizing the air-fuel mixture, which impacts converter efficiency.
- Avoid using leaded fuels or fuel additives not approved for catalytic converter-equipped vehicles.
Issolvi l-problemi
If you experience issues after installing the catalytic converter, consider the following:
- Check Engine Light (CEL) Remains On: If the CEL illuminates after installation, it may indicate an issue with the installation, a faulty sensor, or another underlying engine problem. A diagnostic scan tool can retrieve trouble codes to identify the specific issue.
- Test tal-Emissjonijiet li Ma Għaddiex: If the vehicle fails an emissions test after converter replacement, it could be due to improper installation, a defective converter, or other vehicle components affecting emissions (e.g., oxygen sensors, engine performance issues). Professional diagnosis is required.
- Ħoss ta' tħaxwix: A rattling sound from the exhaust system could indicate a loose heat shield or internal damage to the converter's ceramic substrate.
- Prestazzjoni Mnaqqsa tal-Magna: A clogged or restricted catalytic converter can lead to reduced engine power, poor acceleration, and decreased fuel efficiency.
