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.

Key Features of the Cummins QSB3.3 DEF Aftertreatment Injector

Emission Reduction
- Helps lower NOx emissions by injecting DEF into the exhaust system, facilitating the SCR process.
OEM Precision
- The OEM 5305254 injector is specifically designed for Cummins QSB3.3 engines, ensuring accurate performance and compatibility.
Improved Fuel Efficiency
- By maintaining optimal emissions, this injector can contribute to better overall engine efficiency.
Durability
- Built to withstand the high temperatures and pressures of the exhaust system, ensuring long-lasting performance.
Compliance
- Keeps your engine compliant with EPA emissions regulations, avoiding fines or vehicle restrictions.

Tips for Maintaining the Cummins QSB3.3 DEF Aftertreatment Injector

Regular DEF Refill
- Always use high-quality DEF fluid to avoid contamination that can affect injector performance.
Monitor Injector Health
- Look for signs of injector clogging or failure, such as higher DEF consumption, dashboard warning lights, or reduced emissions efficiency.
Inspect Exhaust System
- Ensure there are no blockages or leaks in the exhaust system that can interfere with DEF injection.
Periodic Cleaning
- Depending on usage, clean the DEF injector periodically to remove crystallized DEF deposits.
Professional Diagnostics
- Have your aftertreatment system checked by a professional technician regularly to detect issues before they become serious.

The Cummins QSB3.3 DEF Aftertreatment Injector (OEM 5305254) is crucial for maintaining efficient emissions control in your engine. By following recommended maintenance practices, you can keep your emissions system functioning optimally and extend the life of your diesel engine. At TamerX Diesel Parts, we offer high-quality, OEM products that help you stay compliant with regulations while keeping your engine in peak condition.

The DEF (Diesel Exhaust Fluid) aftertreatment injector is a critical part of modern diesel engines designed to reduce harmful emissions. This injector sprays DEF into the exhaust system to break down harmful nitrogen oxide (NOx) emissions. When the DEF aftertreatment injector fails, it can cause a variety of performance and emissions issues that need to be addressed promptly.

Common Symptoms of a Failing DEF Aftertreatment Injector:

Check Engine Light
- One of the first indicators of a DEF injector issue is the activation of the check engine light. This warning signals that the engine's computer has detected a problem with the aftertreatment system, which could include the DEF injector.
Increased NOx Emissions
- A failing DEF injector may not properly reduce NOx emissions, causing your vehicle to release more pollutants into the environment. This can result in a failed emissions test.
Excessive Exhaust Smoke
- If the DEF injector isn’t working correctly, you may notice excessive white smoke coming from the exhaust. This occurs when the injector isn’t properly dosing DEF, leading to incomplete reduction of emissions.
Poor Fuel Efficiency
- A malfunctioning DEF aftertreatment system can impact overall engine efficiency, leading to a decrease in fuel economy as the engine struggles to maintain optimal performance.
Unusual Noises
- A defective DEF injector might create unusual hissing or clicking sounds from the exhaust system due to improper spraying or blockages.
Engine Derate:
- Many diesel engines have built-in protection systems that limit engine power when the DEF system isn’t functioning correctly. If your engine is in derate mode, it may be due to a failing DEF injector.

The DEF aftertreatment injector plays a vital role in maintaining your vehicle’s emissions compliance and overall performance. Identifying the symptoms of a failing DEF injector early on can help avoid more serious issues, including engine derating and increased emissions. If you notice any of these signs, it’s crucial to have your DEF system inspected and serviced to keep your diesel engine running smoothly and efficiently.

TAMERX DIESEL REVIEWS

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
