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 Detroit 60 Series engines, particularly the 12.7L and 14.0L models, are renowned for their durability and performance in heavy-duty applications. One crucial component that contributes to their efficiency and emissions control is the EGR (Exhaust Gas Recirculation) valve. The OEM 23539301 EGR valve is a vital part for these engines. Here are five key points about this essential component:

  • Improved Emissions Control

    • The OEM 23539301 EGR valve helps reduce nitrogen oxide (NOx) emissions by recirculating a portion of the engine's exhaust gas back to the engine cylinders. This process lowers the combustion temperature and reduces the formation of NOx, helping the engine comply with environmental regulations.

  • Enhanced Engine Performance

    • By maintaining optimal combustion temperatures and reducing the production of harmful emissions, the EGR valve contributes to improved engine performance. The OEM 23539301 ensures that the engine runs efficiently, providing reliable power and better fuel economy.

  • Durability and Reliability

    • Built to meet Detroit's stringent quality standards, the OEM 23539301 EGR valve is designed for long-lasting durability and reliability. It is manufactured using high-quality materials that can withstand the harsh conditions of heavy-duty engine operation, ensuring a longer service life compared to aftermarket alternatives.

  • Easy Installation and Maintenance

    • The OEM 23539301 EGR valve is designed for straightforward installation and maintenance. It comes with precise fittings and connections that match the specifications of the Detroit 60 Series engines, making it easier for mechanics to replace faulty valves and perform routine maintenance without hassle.

  • Compatibility

    • Specifically engineered for the Detroit 60 Series 12.7L and 14.0L engines from 2004 to 2007, the OEM 23539301 EGR valve guarantees a perfect fit and optimal performance. Using genuine OEM parts helps maintain the integrity and value of your engine, ensuring it operates as intended and avoiding potential issues associated with non-OEM parts.

Investing in high-quality, OEM components like the Detroit 60 Series EGR valve is essential for maintaining the performance, efficiency, and longevity of your engine. Properly functioning EGR valves help keep your engine compliant with emissions regulations while ensuring it runs smoothly and efficiently, providing reliable power for your heavy-duty applications.

The Exhaust Gas Recirculation (EGR) valve plays a crucial role in reducing emissions and improving the efficiency of your vehicle's engine. When an EGR valve goes bad, it can cause several performance issues. Here are five key signs that your EGR valve may be malfunctioning:

  • Rough Idling and Stalling

    • One of the most common signs of a bad EGR valve is rough idling or frequent stalling. If the valve is stuck open, it can cause an excessive amount of exhaust gases to enter the intake manifold, disrupting the air-fuel mixture and causing the engine to run poorly at idle.

  • Increased Fuel Consumption

    • A malfunctioning EGR valve can lead to inefficient combustion, which often results in increased fuel consumption. If you notice a significant drop in fuel economy, it could be due to an EGR valve that is not regulating the exhaust gases properly.

  • Check Engine Light

    • The check engine light is a clear indicator that something is wrong with your vehicle. A failing EGR valve can trigger this light, as the engine control unit (ECU) detects abnormal readings related to the exhaust gas recirculation process. Diagnostic trouble codes (DTCs) related to the EGR system can be read using an OBD-II scanner.

  • Poor Engine Performance

    • If the EGR valve is stuck closed, it can lead to higher combustion temperatures, causing knocking or pinging sounds from the engine. This condition can also result in poor acceleration, loss of power, and overall sluggish engine performance.

  • Emissions Test Failure

    • A faulty EGR valve can cause your vehicle to fail an emissions test. Since the EGR system is designed to reduce nitrogen oxide (NOx) emissions, any malfunction can lead to higher levels of these pollutants, resulting in a failed emissions test and potential fines or penalties.

If you experience any of these symptoms, it is essential to have your EGR valve inspected and, if necessary, replaced. Addressing EGR valve issues promptly can help maintain your vehicle's performance, fuel efficiency, and compliance with emissions regulations.
