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 ISX EGR Valve (OEM 4955969RX) for models from 2007 to 2010 is a crucial component in the emission control system, ensuring the engine runs efficiently and meets environmental standards. Identifying the signs of a failing EGR valve early can help prevent more severe engine issues and maintain your vehicle’s performance. Here are some common symptoms that indicate your Cummins ISX EGR valve might need attention.

  • Rough Idling

    • One of the first signs of a failing EGR valve is rough idling. If your engine feels uneven or vibrates excessively while idling, it could be due to an EGR valve that is not functioning properly.

  • Engine Misfires

    • Misfires occur when the EGR valve fails to supply the correct amount of exhaust gases to the combustion chamber, leading to incomplete combustion and causing the engine to run erratically.

  • Decreased Fuel Efficiency

    • A sudden drop in fuel efficiency often points to a problem with the EGR valve. If the valve is clogged or not opening and closing correctly, it can disrupt the optimal fuel-air mixture, leading to higher fuel consumption.

  • Check Engine Light

    • The check engine light can illuminate for various reasons, including issues with the EGR valve. Diagnostic trouble codes related to the EGR system can help pinpoint the exact problem.

  • Black Smoke from Exhaust

    • If you notice black smoke coming from your exhaust, it may indicate that the EGR valve is not recirculating exhaust gases properly, leading to an overly rich fuel mixture and excessive smoke.

  • Hard Starting

    • Difficulty starting the engine, especially in cold weather, can be a symptom of a failing EGR valve. Insufficient exhaust gas recirculation during startup can cause the engine to struggle to turn over.

  • Poor Acceleration

    • If your vehicle hesitates or struggles to accelerate smoothly, a faulty EGR valve might be the cause. Inconsistent exhaust gas recirculation can affect the engine’s ability to respond to acceleration demands.

Recognizing the signs of a failing Cummins ISX EGR Valve, such as rough idling, engine misfires, decreased fuel efficiency, an illuminated check engine light, black exhaust smoke, hard starting, and poor acceleration, is essential for early intervention. Regular maintenance and prompt replacement of malfunctioning EGR valves help maintain optimal engine performance and extend your vehicle's lifespan.

The Exhaust Gas Recirculation (EGR) valve is an essential component in your vehicle's emission control system. It helps reduce nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gases back into the engine's intake manifold. Over time, EGR valves can become clogged with carbon deposits or fail due to wear and tear. Knowing when to replace your EGR valve is crucial for maintaining your vehicle’s performance and complying with emission standards.

Factors Affecting EGR Valve Replacement Frequency

  • Vehicle Age and Mileage

    • Typically, EGR valves should be inspected every 50,000 miles and may need to be replaced between 70,000 to 100,000 miles. However, this can vary depending on the make and model of your vehicle, as well as your driving habits.

  • Driving Conditions

    • Vehicles driven primarily in urban areas with frequent stop-and-go traffic may experience faster carbon buildup in the EGR valve. This can necessitate more frequent cleaning or replacement compared to vehicles driven mostly on highways.

  • Maintenance History

    •  Regular maintenance, including periodic cleaning of the EGR valve, can extend its lifespan. If the valve is cleaned regularly, it may not need to be replaced as often. Skipping routine maintenance can lead to quicker degradation and the need for earlier replacement.

  • Fuel Quality

    • Using high-quality fuel can reduce the amount of carbon buildup in the EGR valve. Poor-quality fuel can contribute to faster clogging and a shorter lifespan for the valve.Regular inspections and maintenance can help detect EGR valve issues early, potentially allowing for cleaning instead of replacement. However, if the valve is severely clogged or damaged, replacement is necessary to ensure optimal engine performance and emissions control.

In conclusion, the frequency of EGR valve replacement depends on several factors, including vehicle age, mileage, driving conditions, maintenance history, and fuel quality. Regular inspection and maintenance can extend the life of your EGR valve, but it is generally recommended to inspect it every 50,000 miles and consider replacement around 70,000 to 100,000 miles. Being aware of the symptoms of a failing EGR valve can help you take timely action to maintain your vehicle’s performance and emissions compliance.

Symptoms may include rough idling, power loss, black smoke, increased fuel consumption, and check engine lights.

Excessive carbon deposits can clog the valve, restricting movement and disrupting proper exhaust gas flow control.

Poor combustion, excessive soot, faulty sensors, or oil contamination can lead to early valve wear or sticking.

Faulty wiring, failed sensors, or actuator motor problems can prevent proper EGR valve operation.
