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 fuel injector in your International Navistar MaxxForce DT, 9, or 10 engine is essential for delivering the right amount of fuel to the combustion chamber. Over time, injectors can become clogged or worn out, leading to various engine problems. Recognizing the early signs of a failing fuel injector, such as the International Navistar MaxxForce DT, 9, 10 Fuel Injector (OEM 5010985R91), can help you prevent further damage to your engine and avoid costly repairs.

Symptoms of a Failing Fuel Injector

  • Engine Misfires

    • A common sign of a bad fuel injector is engine misfiring. This happens when the injector doesn't supply enough fuel to the engine, causing incomplete combustion.

  • Poor Fuel Efficiency

    •  If you're noticing reduced fuel efficiency or more frequent trips to the gas station, it could be due to a malfunctioning fuel injector not regulating fuel properly.

  • Rough Idling

    •  If the engine is idling roughly or feels shaky, it could be a sign that one or more fuel injectors are clogged or malfunctioning.

  • Excessive Smoke

    • A bad injector can cause excessive smoke from the exhaust, which is often a result of too much or too little fuel being delivered to the combustion chamber.

  • Check Engine Light

    • When a fuel injector begins to fail, it may trigger the check engine light, indicating that there’s a problem with fuel delivery or engine performance.

Spotting the signs of a failing fuel injector early can save you from bigger engine problems and costly repairs. If you notice any of the above symptoms, it might be time to replace your fuel injectors.

By investing in reliable parts, you can keep your engine running efficiently and avoid unnecessary downtime.

Fuel injectors play a vital role in delivering the precise amount of fuel to your engine for efficient combustion. Over time, fuel injectors can become clogged with dirt, debris, or carbon deposits, leading to performance issues. Knowing the signs of a clogged fuel injector can help you address the problem early, ensuring your engine runs smoothly and efficiently.

  • Engine Misfires

    • A clogged fuel injector may cause one or more cylinders to misfire. This can result in rough idling, stuttering, or vibrations while driving, especially during acceleration.

  • Poor Fuel Efficiency

    • If your fuel injector is clogged, your engine won’t be receiving the proper fuel flow, leading to poor fuel combustion. This will cause your vehicle to consume more fuel than usual, leading to reduced fuel efficiency.

  • Loss of Power

    • A clogged injector can prevent the engine from getting the fuel it needs, resulting in sluggish acceleration or a noticeable loss of power, especially when trying to accelerate quickly or drive uphill.

  • Rough Idling

    • If your engine is idling roughly or feels unstable when stopped, it could be due to an uneven fuel supply caused by a clogged fuel injector. The engine may shake or sputter, particularly at lower RPMs.

  • Increased Exhaust Smoke

    • A clogged fuel injector can lead to incomplete combustion, causing the engine to burn excess fuel. This may result in black or dark-colored exhaust smoke, indicating poor fuel combustion.

  • Check Engine Light

    • A clogged fuel injector can trigger the Check Engine Light, as the engine control module (ECM) detects issues with fuel delivery or combustion. A diagnostic scan can reveal injector-related fault codes.

Recognizing the symptoms of a clogged fuel injector—such as engine misfires, poor fuel efficiency, loss of power, rough idling, increased exhaust smoke, and a Check Engine Light—can help you take action before the problem worsens. Regular maintenance, using high-quality fuel, and cleaning your fuel injectors periodically can prevent clogs and ensure your engine runs efficiently. If you notice these signs, it’s best to have your injectors inspected and cleaned by a professional mechanic to restore optimal performance.
