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.

The Exhaust Gas Recirculation (EGR) cooler is a vital component in modern diesel engines, designed to reduce harmful emissions by cooling the exhaust gases before they re-enter the combustion chamber. The Cummins X15 EGR Cooler, OEM 5405814, plays a crucial role in maintaining the efficiency and environmental compliance of engines manufactured between 2017 and 2020. In this blog, we’ll dive into the key functions of the EGR cooler and why it's important to keep this component in good condition.

Key Functions of the Cummins X15 EGR Cooler (OEM 5405814):

  • Reduces Emissions

    • The primary role of the EGR cooler is to lower the temperature of exhaust gases before they are recirculated into the engine, helping to reduce nitrogen oxide (NOx) emissions and comply with environmental regulations.

  • Prevents Overheating

    • By cooling the exhaust gases, the EGR cooler helps prevent the engine from overheating. This protection is essential for keeping the engine and other components in optimal working condition.

  • Enhances Combustion Efficiency:

    • Cooler exhaust gases entering the combustion chamber help maintain balanced combustion temperatures, which leads to more efficient fuel burning and improved engine performance.

  • Improves Engine Durability

    • By managing heat levels and reducing the stress on the engine caused by excessive temperatures, the EGR cooler helps extend the life of the engine, preventing long-term wear and tear.

The Exhaust Gas Recirculation (EGR) cooler is an essential component in reducing harmful emissions by cooling exhaust gases before they re-enter the engine. However, when the EGR cooler fails, it can lead to a range of engine problems and affect your vehicle’s overall performance. Recognizing the symptoms of a bad EGR cooler early on can help prevent more serious damage and costly repairs. In this blog, we’ll explore the common signs of a failing EGR cooler.

Symptoms of a Bad EGR Cooler:

  • White Exhaust Smoke

    • One of the most noticeable signs of a bad EGR cooler is white exhaust smoke. This occurs when coolant leaks into the exhaust system, creating white vapor that is released from the tailpipe.

  • Engine Overheating

    •  A failing EGR cooler can cause your engine to overheat. This happens when the cooler is no longer effectively cooling the exhaust gases, leading to higher engine temperatures.

  • Loss of Coolant

    •  If the EGR cooler is damaged, it may cause a slow coolant leak. You may notice that you need to top off the coolant more frequently, even if there are no visible external leaks.

  • Check Engine Light

    • A malfunctioning EGR cooler can trigger the check engine light. The engine control unit (ECU) may detect irregularities in the EGR system, prompting a warning light on your dashboard.

  • Reduced Engine Performance

    • A bad EGR cooler can negatively impact engine performance. You might experience reduced power, poor acceleration, or a general decrease in efficiency, particularly under load.

  • Rough Idling

    • When the EGR cooler is failing, it can disrupt the air-fuel mixture in the engine, causing rough idling. The engine may feel shaky or uneven when the vehicle is stopped.

A bad EGR cooler can lead to several symptoms, including white exhaust smoke, engine overheating, coolant loss, and poor engine performance. Addressing these issues early can help prevent further engine damage and avoid costly repairs. If you notice any of these signs, it’s important to have your EGR system inspected and repaired to maintain your vehicle’s efficiency and emissions standards. Regular maintenance and timely action can help keep your engine running smoothly.
