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 Diesel Products 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 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.

Taking care of your Cummins X15 DOC (OEM A064G315) is essential for maintaining a properly functioning exhaust aftertreatment system. As the first component in the emissions process, the Diesel Oxidation Catalyst (DOC) relies on clean exhaust flow and proper operating conditions to do its job effectively.

Unlike filters that trap particles, the DOC uses a catalytic reaction to treat exhaust gases. Because of this, contamination and improper engine conditions can reduce its effectiveness over time.

To keep your DOC in good condition, follow these important care practices:

  • Minimize excessive idling
    • Low exhaust temperatures during long idle periods can lead to carbon buildup inside the DOC, reducing its efficiency.
  • Use clean, high-quality fuel
    • Contaminated or poor-quality fuel can introduce deposits that coat the catalyst and interfere with its operation.
  • Address engine issues quickly
    • Problems like leaking injectors or incomplete combustion can send unburned fuel into the exhaust, which may damage the DOC.
  • Monitor for unusual exhaust behavior
    • Reduced efficiency, strong odors, or visible changes in exhaust output can signal that the DOC needs attention.
  • Follow routine inspection intervals
    • Regular checks help identify early signs of restriction or contamination before they become serious issues.
  • Ensure proper operation of related components
    • Sensors and upstream systems must function correctly, as they directly affect how the DOC performs.

By maintaining good engine habits and addressing issues early, you can help extend the life of your Cummins A064G315 DOC and keep your emissions system operating as intended.

Yes, a clogged Diesel Oxidation Catalyst (DOC) can affect how your engine performs. Although the DOC’s primary role is to treat exhaust gases, any restriction within it can disrupt the overall balance of the engine system.

When the DOC becomes clogged with soot, ash, or other contaminants, it restricts the flow of exhaust gases. This creates backpressure, which can interfere with normal engine operation.

Here’s how a clogged DOC can impact your engine:

  • Restricted exhaust flow
    • A blockage makes it harder for exhaust gases to exit, forcing the engine to work against increased pressure.
  • Reduced acceleration and responsiveness
    • The engine may feel sluggish because it cannot efficiently expel exhaust and take in fresh air.
  • Increased fuel consumption
    • The engine may burn more fuel as it tries to compensate for restricted airflow and inefficient combustion.
  • Higher operating temperatures
    • Trapped exhaust gases can raise temperatures within the system, which may affect nearby components over time.
  • Added strain on emissions components
    • A clogged DOC can impact downstream parts like the DPF, leading to further complications if not addressed.

Addressing a clogged DOC early helps restore proper exhaust flow and prevents additional stress on your engine and emissions system.

Yes, factors such as excessive soot, oil contamination, or poor maintenance can shorten the lifespan of the catalyst and reduce its effectiveness.

In many cases, fault codes may need to be cleared after installation so the engine control module can recognize the new component.

The DOC unit typically weighs around 50 lbs and is built with a compact but durable design suitable for heavy-duty exhaust systems.

Using the correct OEM part ensures proper fitment, correct exhaust flow characteristics, and reliable compatibility with the Cummins X15 aftertreatment system.
