As is the case for the majority of the diesel products sold on Tamerx, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Cummins B6.7 SCR Outlet Catalyst Module 2022-2026: OEM 5516224 is an important component of the Selective Catalytic Reduction (SCR) system, designed to help reduce harmful nitrogen oxide (NOx) emissions produced by compatible Cummins B6.7 diesel engines. It supports chemical reactions that convert nitrogen oxides primarily into nitrogen and water vapor before exhaust gases leave the aftertreatment system.
The outlet catalyst works alongside the Diesel Exhaust Fluid (DEF) dosing system and other emissions-control components to support effective exhaust treatment and help maintain the intended emissions requirements of compatible Cummins B6.7 applications.
What Does the SCR Outlet Catalyst Module Do?
- Reduces harmful NOx emissions The catalyst promotes chemical reactions that convert nitrogen oxides into less harmful substances before exhaust gases are released into the atmosphere.
- Supports the SCR treatment process It provides the catalytic surface needed for effective NOx reduction as exhaust gases pass through the module.
- Works with Diesel Exhaust Fluid Ammonia produced from injected DEF reacts with nitrogen oxides inside the SCR catalyst to support proper emissions treatment.
- Completes an important stage of exhaust treatment The outlet catalyst helps reduce remaining nitrogen oxides before exhaust gases exit the aftertreatment system.
- Supports proper exhaust flow The module allows exhaust gases to pass through the catalyst along the intended exhaust pathway.
- Works with emissions monitoring components NOx and temperature sensors help the electronic control system monitor exhaust conditions and evaluate SCR treatment effectiveness.
- Helps maintain emissions compliance Effective NOx reduction supports the emissions-control requirements established for compatible Cummins B6.7 applications.
Essential for Effective NOx Reduction
The Cummins B6.7 SCR Outlet Catalyst Module (OEM 5516224) plays an essential role in maintaining proper exhaust treatment. If the catalyst becomes contaminated, damaged, restricted, or inefficient, it may contribute to SCR efficiency faults, abnormal NOx readings, emissions warning lights, or operating restrictions.
Using specification-correct DEF, maintaining the dosing system, and addressing exhaust or sensor-related problems promptly can help protect the catalyst and support reliable aftertreatment operation.
An SCR Outlet Catalyst Module plays an important role in reducing nitrogen oxide (NOx) emissions from a diesel engine. Its lifespan depends on DEF quality, exhaust temperatures, engine condition, and proper aftertreatment maintenance. Regular inspections and preventive maintenance can help reduce premature catalyst deterioration and extend its service life.
Here are several ways to prolong the lifespan of your SCR Outlet Catalyst Module:
- Use the correct Diesel Exhaust Fluid (DEF) Always use DEF that meets manufacturer specifications. Contaminated or incorrect DEF can cause deposits and interfere with proper SCR catalyst operation.
- Maintain the DEF Doser Injector Inspect the injector for leaks, crystallization, and blockages. Proper DEF distribution helps the SCR system reduce NOx emissions effectively.
- Prevent oil and coolant contamination Repair engine problems that allow oil or coolant to enter the exhaust system, as these substances can coat or damage the catalyst material.
- Monitor exhaust temperatures Excessive exhaust heat can damage the internal catalyst substrate. Address abnormal temperature conditions before they cause permanent deterioration.
- Keep the fuel system properly maintained Faulty fuel injectors, incorrect fuel delivery, and incomplete combustion can contribute to excessive soot and unfavorable exhaust conditions.
- Inspect NOx sensors and electrical connections Faulty sensors, damaged wiring, or corroded connectors can interfere with SCR monitoring and DEF dosing control.
- Address exhaust leaks promptly Inspect exhaust pipes, clamps, gaskets, and connections. Leaks can affect exhaust conditions and interfere with accurate emissions monitoring.
- Avoid unnecessary extended idling Prolonged low-temperature operation can contribute to deposits and prevent the aftertreatment system from operating under favorable conditions.
- Respond to SCR warning lights immediately Investigate recurring SCR efficiency codes, DEF warnings, and emissions-related faults before they develop into more serious problems.
- Follow manufacturer maintenance recommendations Regularly inspect the aftertreatment system and service related components according to the recommended maintenance schedule.
An SCR Outlet Catalyst Module does not typically require replacement at a fixed mileage. Using the correct DEF, maintaining the engine, and addressing aftertreatment problems early can help preserve catalyst effectiveness and prevent premature failure.
The 5516224 supports selective catalytic reduction by helping convert nitrogen oxides in diesel exhaust into nitrogen and water.
The 5516224 uses catalytic reactions involving ammonia derived from DEF to help reduce nitrogen oxide emissions in the exhaust stream.
The 5516224 contributes to the proper operation of the B6.7 emissions-control system by supporting the treatment of nitrogen oxides.
Possible warning signs include SCR-related fault codes, abnormal NOx readings, emissions warnings, and reduced catalyst conversion efficiency.
