3. Key Features
- CARB Compliant: EO# D-182-62. For use on OBDII vehicles (1996 and newer) and non-OBD vehicles (1995 and older). Consult your state’s aftermarket converter regulations, especially for California, Colorado, New York, and other states requiring CARB-compliant replacement converters.
- Direct-Fit Design: Engineered for bolt-off, bolt-on installation. OE-style converter with integrated manifold assemblies that attach directly to the engine cylinder head and match all downstream connections.
- Superior Technology: Features an optimal high-technology washcoat formulated for enhanced performance in emissions reduction.
- Consistent Performance: Utilizes a precise OE-style coating process to apply catalyst material to the substrate, ensuring reliable emissions compliance.
- Durable Construction: Built with thick OE-style flanges, hangers, and brackets for strength. Features a stainless-steel body with aluminized pipe and heat shields for long-term durability.

4. Installation (Setup)
Installation of the Walker CalCat CARB 83185 catalytic converter is intended for experienced automotive technicians due to the specialized nature of exhaust system components.
- Preparation: Ensure the vehicle is safely lifted and secured. Allow the exhaust system to cool completely before beginning work.
- Removal of Old Unit: Disconnect oxygen sensors and unbolt the existing catalytic converter and manifold assembly from the engine cylinder head and downstream exhaust pipe.
- Inspection: Inspect all mounting surfaces and connections for damage or corrosion. Clean as necessary.
- Gasket Placement: Install new gaskets (if supplied) on the mounting surfaces. Ensure correct orientation.
- New Unit Installation: Carefully position the Walker CalCat 83185 assembly. Bolt it to the engine cylinder head and connect it to the downstream exhaust pipe. Tighten all bolts to manufacturer specifications.
- Oxygen Sensor Reconnection: Reconnect all oxygen sensors. Ensure wiring is routed correctly and not pinched or stressed.
- Final Check: Verify all connections are secure and there are no exhaust leaks.

5. Operation
The Walker CalCat CARB 83185 catalytic converter functions as a critical component of your vehicle's emissions control system. It converts harmful pollutants in the exhaust gas into less toxic substances through chemical reactions.
- Emissions Reduction: Designed to reduce carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) from the engine exhaust.
- OBDII Compliance: Engineered to work effectively with On-Board Diagnostics II (OBDII) systems, helping to prevent the illumination of the Check Engine Light for emissions-related codes.
- No Break-In Required: The converter is ready to operate immediately upon installation, thanks to its application-specific shell design and mat compression.

6. Maintenance
Catalytic converters are generally maintenance-free components. However, their longevity and performance are directly linked to the overall health of your vehicle's engine and exhaust system.
- Regular Engine Maintenance: Ensure your engine receives regular tune-ups, oil changes, and air filter replacements. A properly running engine prevents excessive unburnt fuel from reaching the converter, which can cause overheating and damage.
- Address Engine Malfunctions Promptly: Misfires, rich fuel mixtures, or faulty oxygen sensors can severely impact converter performance and lifespan. Address any Check Engine Light warnings immediately.
- Avoid Contaminants: Prevent leaded fuel, excessive oil consumption, or coolant leaks from entering the exhaust system, as these can poison the catalyst.
7. Troubleshooting
If you experience issues after installing the catalytic converter, consider the following:
- Check Engine Light (CEL) On:
- Verify all oxygen sensors are correctly installed and connected.
- Ensure there are no exhaust leaks before or after the converter.
- Diagnose the vehicle's OBDII system for specific trouble codes. A CEL related to converter efficiency (e.g., P0420, P0430) may indicate an underlying engine issue, incorrect installation, or, in rare cases, a faulty converter.
- Smog Test Failure (CARB States):
- While this product is listed as CARB compliant (EO# D-182-62), some users in California have reported issues passing smog tests.
- It is crucial to verify that the specific part number and EO number are accepted in your state or region before purchase and installation. Regulations can vary and may be subject to change.
- Ensure the vehicle's engine is in optimal operating condition, as other engine issues can cause emissions failures.
- Exhaust Leaks:
- Re-check all bolted connections for proper torque.
- Inspect gaskets for damage or improper seating.
