SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

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 X15 DOC Filter 2024-2027: OEM 5511273 is a Diesel Oxidation Catalyst (DOC) designed to help reduce harmful exhaust emissions produced by compatible Cummins X15 diesel engines. It is an important component of the diesel aftertreatment system, helping convert carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful substances.

The DOC filter also supports the operation of the Diesel Particulate Filter (DPF) by helping create the exhaust conditions needed for effective soot regeneration.

What Does the DOC Filter Do?

  • Reduces carbon monoxide emissions The DOC promotes chemical reactions that convert harmful carbon monoxide into carbon dioxide before exhaust gases move through the aftertreatment system.

  • Oxidizes unburned hydrocarbons It helps break down unburned fuel compounds in the exhaust stream, reducing harmful hydrocarbon emissions.

  • Supports DPF regeneration The catalyst helps generate the heat required for the DPF to burn accumulated soot during active regeneration.

  • Helps maintain proper exhaust treatment It provides an important initial stage of exhaust treatment before gases pass through downstream emissions-control components.

  • Works with the DPF system The DOC prepares exhaust gases for further treatment, while the DPF captures soot and particulate matter.

  • Supports aftertreatment temperature management Oxidation reactions inside the catalyst help establish suitable exhaust temperatures for downstream aftertreatment processes.

  • Helps maintain emissions compliance Effective oxidation of exhaust pollutants supports the emissions-control requirements established for compatible Cummins X15 applications.

An Essential Component of Diesel Exhaust Treatment

The Cummins X15 DOC Filter (OEM 5511273) plays an important role in reducing exhaust pollutants and supporting proper DPF operation. If the catalyst becomes contaminated, damaged, or inefficient, it may contribute to incomplete regeneration, emissions warning lights, aftertreatment fault codes, or operating restrictions.

Maintaining the engine, addressing fuel or oil-related issues promptly, and following recommended aftertreatment maintenance procedures can help protect the DOC filter and support reliable exhaust treatment.

A Diesel Oxidation Catalyst (DOC) Filter is an important component of a diesel engine's aftertreatment system. It helps reduce harmful exhaust emissions by converting carbon monoxide and unburned hydrocarbons into less harmful substances. When the DOC Filter becomes damaged, contaminated, or ineffective, it can affect exhaust treatment and contribute to engine operating problems.

Here are several signs that your DOC Filter may be failing:

  • Check engine or emissions warning light The engine control system may detect abnormal aftertreatment conditions and trigger a warning light on the dashboard.

  • Recurring aftertreatment fault codes Diagnostic trouble codes related to exhaust temperatures, catalyst efficiency, or regeneration problems may indicate a DOC Filter issue.

  • Frequent regeneration cycles A deteriorating DOC Filter may interfere with the heat generation needed for DPF regeneration, resulting in repeated or incomplete regeneration attempts.

  • Excessive exhaust smoke Increased exhaust smoke may indicate incomplete combustion or problems within the aftertreatment system that require further inspection.

  • Restricted exhaust flow A severely contaminated or damaged DOC Filter can increase exhaust backpressure and interfere with normal engine operation.

  • Abnormal exhaust temperatures A DOC Filter that is not functioning correctly may fail to produce the expected temperature changes during aftertreatment operation.

  • Engine derate Persistent aftertreatment faults may cause the engine control system to restrict vehicle operation until the problem is corrected.

  • Unusual exhaust odors A failing DOC Filter may allow more unburned hydrocarbons to pass through the exhaust system, resulting in noticeable odors.

  • Physical catalyst damage Cracked, melted, contaminated, or broken internal catalyst material can indicate that the DOC Filter requires replacement.

These symptoms do not automatically confirm DOC Filter failure. Faulty temperature sensors, fuel system problems, exhaust leaks, DPF restrictions, and oil or coolant contamination can produce similar warning signs. A complete aftertreatment system inspection can help determine whether the DOC Filter needs servicing or replacement.
