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.

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 Cummins ISB 6.7L EGR Cooler (OEM 5566897 | 5341879RX) is a vital component in diesel engines, specifically designed for the 2017-2021 models. This component plays a crucial role in reducing emissions and improving engine efficiency. Here’s an in-depth look at what it does and why it’s essential.

Function of the EGR Cooler

  • Emission Reduction
    • The EGR (Exhaust Gas Recirculation) cooler helps to lower nitrogen oxide (NOx) emissions by cooling the exhaust gases before they are recirculated into the engine's intake.
  • Improved Combustion Efficiency
    • By cooling the exhaust gases, the EGR cooler ensures a more complete and efficient combustion process, leading to better engine performance.
  • Engine Protection
    • The cooler reduces the temperature of the exhaust gases, protecting the engine components from excessive heat and potential damage.

How the EGR Cooler Works

  • Heat Exchange Process
    • The EGR cooler uses a network of tubes and fins to transfer heat from the exhaust gases to the engine coolant, effectively reducing the temperature of the gases.
  • Recirculation of Cooled Gases
    • Cooled exhaust gases are then recirculated back into the engine's intake manifold, where they mix with the incoming air, reducing combustion temperatures and NOx formation.
  • Durable Construction
    • Designed to withstand high temperatures and pressures, the EGR cooler ensures long-lasting performance and reliability.

Benefits of Using OEM 5566897 | 5341879RX EGR Coolers

  • Enhanced Engine Performance
    • Reducing exhaust gas temperatures leads to more efficient engine operation and improved power output.
  • Compliance with Emission Standards
    • Proper functioning of the EGR cooler helps meet stringent emission regulations, ensuring your vehicle remains environmentally friendly.
  • Extended Engine Life
    • By lowering combustion temperatures, the EGR cooler protects vital engine components, extending their lifespan and reducing maintenance costs.

The EGR (Exhaust Gas Recirculation) cooler is an important component of a diesel engine. It helps to reduce the emission of harmful gases by recirculating exhaust gases back into the engine. However, when an EGR cooler fails, it can lead to serious problems for the engine and the vehicle as a whole.

  • Reduced Engine Performance
    • One of the most common signs of a failed EGR cooler is reduced engine performance. When the EGR cooler fails, it can cause the engine to work harder and become less efficient. This can result in a decrease in power and acceleration, which can be noticed when driving the vehicle.
  • Engine Overheating
    • Another issue that can arise from a failed EGR cooler is engine overheating. The EGR cooler is responsible for cooling down the exhaust gases before they are recirculated back into the engine. When the EGR cooler fails, it can cause the engine to overheat due to the increased temperature of the exhaust gases.
  • Increased Emissions
    • A failed EGR cooler can also lead to an increase in emissions. The EGR system is designed to reduce the amount of harmful gases that are emitted by the engine. When the EGR cooler fails, it can cause the engine to produce more emissions than it normally would.
  • Clogged Engine Components
    • A failed EGR cooler can also lead to clogged engine components. The exhaust gases that are recirculated back into the engine can contain soot and other particles that can build up over time. This can lead to clogged engine components, which can cause further damage to the engine.
  • Costly Repairs
    • If a failed EGR cooler is not addressed promptly, it can lead to costly repairs. The longer the issue goes unresolved, the more damage can be done to the engine and other components. Repairs can include replacing the EGR cooler, cleaning clogged engine components, and fixing any other damage that may have occurred.

A failed EGR cooler can cause a range of problems for a diesel engine. It is important to address the issue promptly to prevent further damage and costly repairs. Regular maintenance and inspections can help to identify any potential issues with the EGR system before they become major problems.

A failing EGR cooler can cause engine overheating, loss of coolant, decreased fuel efficiency, and increased emissions, potentially leading to engine damage if not addressed promptly.

By lowering the temperature of recirculated exhaust gases, the cooler helps maintain ideal combustion temperatures, reducing NOx emissions and improving engine efficiency.

Key indicators include excessive white exhaust smoke, coolant loss without visible leaks, overheating, and diagnostic trouble codes related to the EGR system.

Regular cleaning of the EGR system, use of high-quality coolant, adherence to maintenance intervals, and periodic inspection of connections can help prevent issues.
