As is the case for the majority of the diesel products sold on Tamerx Diesel Products, 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 Diesel Products 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.
Operating as a key element in the exhaust aftertreatment system, the Cummins ISX15 SCR Outlet Catalyst Module (2011–2015) OEM 2511210C91 helps manage emissions before treated exhaust leaves the system. Manufactured according to original equipment specifications, it provides accurate fitment for compatible Cummins ISX15 engines within the specified model years. This catalyst module supports the selective catalytic reduction process, helping convert nitrogen oxide (NOx) emissions into less harmful compounds. Its heavy-duty construction is designed to tolerate elevated exhaust temperatures, vibration, and rigorous diesel operating conditions. Suitable for fleet maintenance and professional diesel service, this OEM SCR outlet catalyst module helps maintain proper emissions system function and dependable long-term operation.

The SCR Outlet Catalyst Module associated with OEM 2511210C91 operates in a demanding part of the exhaust aftertreatment system, where it is exposed to high temperatures, vibration, and exhaust contaminants. Proper care of the entire SCR and DEF system is therefore one of the best ways to protect the catalyst and extend its useful life.
One fitment detail is worth noting: 2511210C91 is listed in available parts catalogs as a Navistar/International component rather than a Cummins-numbered part, so compatibility with a specific ISX15 application should be verified by VIN or engine serial number before replacement.
Ways to Help Your SCR Catalyst Last Longer
- Use clean, specification-correct DEF
- Poor-quality, diluted, or contaminated Diesel Exhaust Fluid can interfere with SCR operation and contribute to deposits within the aftertreatment system.
- Keep the DEF dosing system healthy
- A malfunctioning doser can supply too much or too little DEF. Incorrect dosing may cause crystallization, deposits, or reduced catalyst efficiency.
- Address engine problems quickly
- Excessive oil consumption, coolant entering the exhaust, or abnormal combustion can contaminate the catalyst and shorten its lifespan.
- Watch for exhaust leaks
- Leaks upstream of the SCR system can change exhaust temperatures and sensor readings, interfering with proper emissions-system operation.
- Maintain the DOC and DPF
- Problems with upstream aftertreatment components can affect the temperature and condition of exhaust entering the SCR section.
- Avoid excessive low-temperature operation when possible
- Long periods of idling and repeated short operating cycles can prevent the aftertreatment system from consistently reaching effective operating temperatures.
- Pay attention to warning lights and fault codes
- SCR efficiency, NOx sensor, DEF dosing, or temperature-related faults should be diagnosed promptly instead of allowing the problem to continue.
- Inspect mounting points and connections
- Check clamps, brackets, joints, and surrounding exhaust components for looseness, corrosion, cracks, or damage that could place unnecessary stress on the module.
Protecting the Catalyst for the Long Run
The best way to prolong the life of an SCR Outlet Catalyst Module is to maintain the systems around it. Clean DEF, correct dosing, a healthy engine, proper exhaust temperatures, and timely repairs can prevent contamination and excessive deposits from damaging the catalyst.
Treating an SCR efficiency fault as a system-wide diagnostic issue is also important. Before replacing the catalyst, the DEF doser, NOx sensors, exhaust leaks, temperature sensors, and upstream aftertreatment components should be checked, since problems in these areas can sometimes mimic catalyst failure.
An SCR Outlet Catalyst Module generally requires little direct maintenance, but its lifespan depends heavily on the condition of the engine, DEF system, and other aftertreatment components. Good preventive maintenance can help protect the catalyst from contamination, excessive heat, and premature deterioration.
Here are some practical ways to take care of it:
- Use the correct DEF
- Always use clean Diesel Exhaust Fluid that meets the specifications required by your engine manufacturer. Contaminated or improperly stored DEF can cause deposits and SCR system problems.
- Keep the DEF dosing system maintained
- A faulty DEF injector can cause incorrect dosing or crystallization. Address dosing-related fault codes promptly.
- Maintain your engine properly
- Problems such as faulty fuel injectors, turbocharger leaks, EGR issues, or excessive oil consumption can introduce soot, oil, and other contaminants into the aftertreatment system.
- Address warning lights quickly
- Don't continue operating indefinitely with SCR, NOx, DEF, or other emissions-related fault codes. A relatively small problem can eventually affect the catalyst.
- Inspect for exhaust leaks
- Cracked piping, damaged seals, and loose clamps can interfere with exhaust conditions and SCR system monitoring.
- Avoid excessive idling when possible
- Long periods of low-temperature operation can contribute to deposit buildup and prevent the aftertreatment system from consistently reaching effective operating temperatures.
- Watch for abnormal exhaust temperatures
- Overheating can permanently damage the catalyst substrate. Temperature-related fault codes should be investigated rather than repeatedly cleared.
- Have related sensors checked
- NOx and exhaust temperature sensors help the engine control system manage and evaluate SCR operation. Incorrect readings can cause improper system operation.
- Follow the manufacturer's maintenance schedule
- Proper servicing of the engine, DPF, DEF system, and other aftertreatment components helps create the conditions the SCR catalyst needs for a long service life.
The best way to protect your SCR Outlet Catalyst Module is to maintain the entire engine and aftertreatment system, rather than focusing on the catalyst alone. Clean DEF, correct dosing, proper engine operation, and early attention to fault codes can significantly reduce the risk of premature catalyst failure.
Yes, the replacement should match the original 95-degree configuration to maintain correct exhaust alignment and connection geometry.
Yes, deformation of the 2511210C91 weldment can prevent proper alignment with the adjoining aftertreatment components.
The welded seams, mating surfaces, flanges, clamps, and adjoining connections of the 2511210C91 should be inspected for evidence of leakage.
Yes, cracks in the 2511210C91 can allow exhaust leakage and generally require repair or replacement according to the applicable service procedure.
