From the manufacturer
WALKER CATALYTIC CONVERTERS
Walker offers catalytic converters manufactured with a stainless-steel body, aluminized pipe and heat shields, that provide you peace-of-mind with assured compliance by engineers who set the standard. Whether itâs universal or direct-fit, catalytic converters feature an optimal high-technology washcoat and OE-design precious metal load that deliver required reduction in tailpipe emissions to match vehicle application.
FIVE CHECKS BEFORE REPLACING A CATALYTIC CONVERTER
Converters donât fail on their own, complete these five checks before replacing a catalytic converter:
Retrieve / repair all PCM trouble codes, check for any available TSBs or PCM re-flash updates
Repair all exhaust leaks
Make sure vehicle is in proper fuel control
Always check for internal coolant leaks and excessive oil consumption
Make sure you have the right part for the application
WHY A CATALYTIC CONVERTER FAILS
Converters donât fail on their own; failure is usually a symptom of a larger problem. This is why it is important to identify the root cause of the failure and perform the repair prior to installing a new converter. Most catalytic converter failures fall under one of three categories:
Overheated, melted or broken converters
DIRECT-FIT VS. UNIVERSAL CONVERTERS
Walker universal fit catalytic converters have a customizable design with expandable bushings to adapt to connector pipes based on the repair. They may require specialized fabrication and welding for installation. Walker pre-bent routings hangers and flanges for OE-style direct-fit catalytic converters attach to the exhaust system for a direct-fit bolt-off, bolt-on solution. No matter what you select, all converters must meet the emission requirements of the vehicle and cannot be chosen by size alone.
WHAT TO DO IF CHECK ENGINE LIGHT COMES ON?
Troubleshoot an illuminated check engine light by making sure the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains lit, it could be triggered by a faulty oxygen sensor, failing catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor. If the light remains on, make sure to make an appointment with your service provider as soon as possible.
WHAT IS THE DIFFERENCE BETWEEN EPA AND CARB CONVERTERS
EPA-compliant catalytic converters are for use on EPA or Federal emissions certified-vehicles. EPA-compliant catalytic converters cannot be sold or installed in California and Colorado and in certain circumstances in Maine and New York. In those states, you must install a CARB-compliant catalytic converter on CARB emissions certified vehicles in the states of California and Colorado, on all vehicles. CARB-compliant converters contain more catalyst material in order to converter emissions more efficiently and comply with stricter emissions reduction requirements. Check the vehicleâs emissions control information label and consult your stateâs aftermarket converter regulations to select the right catalytic converter.
