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 International Navistar A26 SCR Outlet Catalyst Module 2022-2026: OEM 2522078C1 is an important component of the engine’s Selective Catalytic Reduction (SCR) aftertreatment system. Its primary function is to help reduce harmful nitrogen oxide (NOx) emissions before treated exhaust gases leave the system.
The module works with Diesel Exhaust Fluid (DEF), emissions sensors, and other aftertreatment components to complete an important stage of exhaust treatment.
What Does the SCR Outlet Catalyst Module Do?
- Reduces NOx emissions
- The catalyst provides the surface where ammonia reacts with nitrogen oxides to convert them into less harmful substances.
- Works with the DEF system
- DEF injected upstream breaks down and produces ammonia needed for the SCR chemical reaction.
- Completes the SCR process
- The outlet catalyst provides an important later stage of treatment before exhaust gases exit the aftertreatment system.
- Supports NOx monitoring
- NOx sensors help the electronic control system determine whether the SCR system is reducing emissions as expected.
- Works with other aftertreatment components
- The module functions alongside the DOC, DPF, DEF dosing system, sensors, and electronic controls.
- Maintains proper exhaust treatment
- A healthy catalyst allows exhaust gases to pass through while providing the conditions required for NOx conversion.
- Supports emissions compliance
- Proper SCR operation helps compatible International Navistar A26 applications remain within their intended emissions requirements.
An Essential Part of NOx Reduction
The International Navistar A26 SCR Outlet Catalyst Module (OEM 2522078C1) plays a critical role in the final stages of diesel exhaust treatment. If the catalyst becomes contaminated, damaged, or inefficient, the vehicle may experience SCR efficiency fault codes, emissions warning lights, DEF-related problems, or operating restrictions.
Using specification-correct DEF and promptly addressing dosing, sensor, engine, or exhaust-system problems can help protect the SCR catalyst and maintain reliable aftertreatment operation.
A bad SCR Outlet Catalyst Module can prevent the aftertreatment system from reducing nitrogen oxide (NOx) emissions correctly. Since several components work together within the SCR system, catalyst problems can sometimes be mistaken for sensor, DEF, or exhaust-related faults.
Common signs include:
- Check engine or emissions warning light
- The vehicle may display a warning when the control system detects abnormal SCR operation.
- Recurring SCR efficiency codes
- Catalyst-related fault codes that repeatedly return can indicate that the module is no longer converting NOx effectively.
- High downstream NOx readings
- Elevated NOx levels after the exhaust passes through the catalyst may indicate reduced catalyst effectiveness.
- Engine derate
- Persistent SCR faults may cause the engine control system to restrict vehicle operation until the emissions problem is corrected.
- Abnormal DEF consumption
- Unusually high or low DEF usage may accompany an SCR system problem, although it does not confirm catalyst failure by itself.
- Failed emissions testing
- A deteriorated catalyst may allow NOx emissions to remain above acceptable limits.
- Physical damage to the catalyst
- Cracking, melting, loose internal material, or severe heat damage can prevent the module from functioning correctly.
- Oil, coolant, or soot contamination
- Contaminants entering the exhaust can coat the catalyst material and interfere with the chemical reactions required for NOx reduction.
- Persistent problems after other SCR repairs
- If SCR faults continue after related components have been tested or repaired, the catalyst module may require further evaluation.
A bad SCR Outlet Catalyst Module should be confirmed through proper diagnosis before replacement. Faulty NOx sensors, incorrect DEF dosing, poor DEF quality, exhaust leaks, wiring problems, or engine-related issues can produce many of the same symptoms.
Yes, internal catalyst deterioration, cracking, contamination, or restriction can occur without obvious damage to the outer housing.
Yes, incorrect DEF delivery can interfere with SCR operation and contribute to deposits or other conditions affecting the catalyst module.
Yes, significant deposits or damaged internal catalyst material can interfere with normal exhaust flow through the module.
The DEF system, sensors, exhaust connections, mounting points, adjoining aftertreatment components, and potential contamination sources should be inspected before installation.
