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.

The Cummins ISX EGR Cooler (OEM 4309434NX) is a critical component in controlling emissions in 2003-2006 Cummins engines. This part helps lower the temperature of exhaust gases before they re-enter the engine for combustion, reducing nitrogen oxide emissions and ensuring your diesel engine meets emission standards. In this blog, we’ll cover the function of the EGR cooler, its importance, and tips for maintaining this vital part of your engine system.

Understanding the Function of the Cummins ISX EGR Cooler

  • Reduces Exhaust Temperature
    •  The EGR cooler reduces the temperature of the exhaust gases that are reintroduced into the combustion chamber, ensuring a cleaner and more efficient burn.
  • OEM Quality
    • Designed by Cummins, the OEM 4309434NX EGR Cooler fits perfectly into your engine and meets high durability and quality standards.
  • Improves Emission Control
    •  By cooling the exhaust gases, the EGR cooler helps lower harmful nitrogen oxide emissions, keeping your vehicle in compliance with emission regulations.

Maintenance Tips for Your Cummins ISX EGR Cooler

  • Regular Inspections
    • Check the cooler for leaks or clogs, as these can reduce its effectiveness and lead to engine overheating.
  • Coolant Checks
    • Ensure your coolant levels are maintained properly, as a lack of coolant can overheat the cooler and cause damage.
  • Cleanliness
    •  Clean your EGR cooler periodically to prevent carbon buildup, which can restrict airflow and reduce cooling efficiency.
  • Replace When Necessary
    •  Over time, the EGR cooler can wear down. Replace it with a genuine OEM part like the 4309434NX to ensure the best performance.

The Cummins ISX EGR Cooler (OEM 4309434NX) is essential for controlling emissions and maintaining the efficiency of your engine. By keeping your cooler clean and properly maintained, you ensure a more efficient engine and help meet environmental standards. At TamerX Diesel Parts, we provide top-quality replacement parts to keep your Cummins ISX running smoothly and efficiently for years to come.

The Exhaust Gas Recirculation (EGR) cooler is a vital component of your vehicle’s emissions system, responsible for cooling exhaust gases before they are recirculated into the engine. When the EGR cooler fails, it can lead to several engine and performance issues that should not be ignored. Recognizing the symptoms of a bad EGR cooler can help you address the problem early and prevent costly repairs.

Common Symptoms of a Bad EGR Cooler:

  • White Exhaust Smoke

    • A clear sign of a failing EGR cooler is white smoke coming from the exhaust. This occurs when coolant leaks into the exhaust system, creating steam.

  • Loss of Coolant

    •  If you notice a significant drop in coolant levels without any visible external leaks, it could indicate a leak inside the EGR cooler.

  • Engine Overheating

    • A malfunctioning EGR cooler can cause your engine to overheat, as it disrupts the cooling system and reduces its efficiency.

  • Check Engine Light

    • A failing EGR cooler can trigger the check engine light due to issues with the exhaust gas recirculation process, which affects overall emissions control.

  • Poor Engine Performance

    • The engine may run roughly, idle poorly, or stall when the EGR cooler is not working properly. The disruption in the air-fuel mixture can affect the engine’s performance.

A bad EGR cooler can lead to white exhaust smoke, coolant loss, engine overheating, and poor performance. If you notice any of these symptoms, it's essential to have your vehicle inspected and the EGR cooler replaced if necessary. Addressing EGR cooler issues early can prevent more severe engine damage and keep your vehicle running efficiently.

A cracked cooler may allow coolant into the combustion chamber, causing misfires, smoke, and potential engine damage.

Sustained high exhaust temperatures can weaken internal metal components and reduce cooler lifespan.

Flushing may remove minor deposits, but severe clogging or internal damage usually requires replacement.

It should be inspected regularly during scheduled maintenance to detect early signs of wear or clogging.
