Before installation, verify compatibility using your vehicle's year, make, model, engine, and trim information. Consult your vehicle's service manual for specific exhaust system configurations.

3. Nga waahanga matua

• EPA Compliant: Designed for use on pre-OBDII vehicles (1995 and older) to meet federal emissions standards. Consult local regulations for specific state requirements.
• Direct-Fit Design: Engineered for a bolt-on replacement, featuring OE-style hangers, brackets, routings, and heat shields. This design simplifies installation, eliminating the need for specialized fabrication or welding.
• Assured Performance: Utilizes OE-style high-technology washcoat and optimal precious metal loading to achieve the necessary reduction in tailpipe emissions for the specified vehicle applications.
• Hanga Roa: Features thick OE-style flanges, hangers, and brackets for enhanced strength and longevity. Aluminized heat shields, where originally equipped, protect the vehicle's undercarriage from heat generated by the converter.
• No Break-In Required: Ready for immediate operation upon installation due to application-specific converter shell design and mat compression.

4. Tohutohu Tāuta

Installation of a catalytic converter requires specialized tools and automotive knowledge. It is highly recommended that this component be installed by a qualified automotive technician.

4.1 Nga Tirohanga i mua i te whakaurunga

• Ensure the vehicle's exhaust system is cool before beginning work.
• Inspect the new catalytic converter for any shipping damage.
• Confirm all necessary gaskets, bolts, and spring kits are available. These are typically not included with the converter and must be purchased separately.

4.2 Removal of Old Converter

5. Operation and Emissions Compliance

The catalytic converter is a critical component of your vehicle's exhaust system, responsible for reducing harmful pollutants from engine emissions. It converts toxic gases and pollutants in exhaust gas into less toxic pollutants by catalyzing redox reactions.

This Walker Ultra EPA 15828 converter is designed to maintain optimal exhaust efficiency and ensure your vehicle meets EPA emissions standards for its applicable model years. Proper installation and a well-maintained engine are crucial for the converter's effective operation.

6. Tiaki

Catalytic converters generally require no routine maintenance. However, the longevity and efficiency of the converter are directly linked to the overall health of your engine and exhaust system. Regular vehicle maintenance, including timely oil changes, spark plug replacement, and addressing engine misfires, will help prevent premature converter failure.

• Ensure your engine is running efficiently to prevent unburnt fuel from damaging the converter.
• Periodically inspect the exhaust system for leaks, corrosion, or damage.
• Address any engine warning lights promptly to prevent issues that could affect the catalytic converter.

7. Te Raru

If you experience issues after installing the catalytic converter, consider the following:

7.1 Check Engine Light (CEL)

If the Check Engine Light illuminates after installation, it may indicate an issue with the exhaust system or engine. Common causes related to catalytic converters include:

• Oxygen Sensor Issues: Faulty or improperly installed oxygen sensors can trigger a CEL. Ensure sensors are correctly connected and functioning.
• Nga Rirenga Rerehu: Leaks in the exhaust system, especially near oxygen sensors, can affect readings and trigger a CEL. Inspect all connections for tightness.
• Ngā Take Mahi a te Mīhini: Underlying engine problems (e.g., misfires, rich/lean fuel mixture) can cause the converter to operate inefficiently or become damaged, leading to a CEL. Address engine issues first.

It is recommended to have the vehicle diagnosed by a professional technician using an OBD-II scanner to retrieve diagnostic trouble codes (DTCs) for accurate troubleshooting.
