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.

Temperature monitoring is essential for keeping diesel engines operating within safe and efficient limits. The Cummins QSB temperature sensor plays a key role by measuring heat levels within the engine and sending that information to the engine control module (ECM). This continuous data flow allows the system to adjust engine functions and helps prevent overheating or inefficient operation.

  • Provides Real-Time Temperature Feedback
    The sensor measures coolant or component temperature and converts it into an electrical signal that the ECM uses to monitor engine conditions.
  • Supports Engine Management Adjustments
    Temperature data helps the ECM regulate fuel delivery, timing, and cooling system behavior to maintain proper engine operation.
  • Helps Prevent Overheating and Damage
    By detecting rising temperatures early, the sensor allows the system to trigger warnings or protective actions, reducing the risk of engine failure.
  • Improves Overall Engine Efficiency
    Accurate temperature readings contribute to better combustion control and balanced system performance, supporting consistent operation across different conditions.
  • Designed for Cummins QSB Engines (2011–2024)
    Built to OEM 4384575 specifications, this sensor is intended for compatibility with Cummins QSB applications, ensuring proper integration with the engine’s electrical and cooling systems.

A properly functioning temperature sensor is essential for maintaining engine stability and reliability. In Cummins QSB engines, this component helps ensure accurate heat monitoring, supports system adjustments, and contributes to dependable operation over time.

Temperature sensors play a key role in monitoring engine and exhaust heat levels, providing critical data to the engine control module. This information helps regulate cooling systems, fuel delivery, and emissions functions. When a temperature sensor fails or sends incorrect readings, it can lead to improper system responses that may contribute to overheating conditions.

  • A faulty sensor may report inaccurate temperature readings, causing the system to misjudge actual engine heat levels.
  • If the sensor reads lower than the true temperature, cooling fans may not activate when needed, allowing heat to build up.
  • Incorrect data can affect fuel delivery, leading to inefficient combustion and increased engine temperatures.
  • Cooling system components, such as thermostats or fan controls, may not operate correctly due to faulty sensor input.
  • In exhaust systems, inaccurate temperature readings can disrupt regeneration cycles, potentially causing excessive heat buildup.
  • Warning lights or erratic temperature gauge behavior may indicate a failing sensor.

While a bad temperature sensor may not always directly cause overheating, it can prevent the engine from properly managing heat. Prompt diagnosis and replacement help ensure accurate temperature monitoring and protect the engine from potential damage.

Yes, damaged wiring or poor connections can prevent accurate signal transmission.

It sends an electrical signal that represents the current temperature reading.

It responds quickly to temperature changes and provides near real-time updates.

Yes, contamination or corrosion can reduce accuracy over time.
