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.

When determining if the Cummins QSB Temp Sensor (OEM 4384577) is compatible with your engine, it’s important to go beyond just the part name. While this sensor is widely used, proper verification ensures it will fit and function correctly with your specific setup.

This temperature sensor is commonly designed for Cummins QSB 6.7L and B6.7 engines, particularly within the 2011–2024 range. However, compatibility can still vary depending on your engine’s exact configuration.

To confirm fitment, here’s what you should check:

  • Confirm your engine model and year
    • Make sure your engine is a Cummins QSB (or compatible platform like B6.7). This part is typically used across 2011–2024 applications, but model matching is the first step.
  • Use your Engine Serial Number (ESN)
    • This is the most accurate way to verify compatibility. The ESN identifies your engine’s exact build and ensures the correct part match.
  • Check your current sensor’s part number
    • If the existing sensor shows 4384577, you can confidently replace it with the same component.
  • Verify cross-platform usage carefully
    • While this sensor may appear across multiple Cummins engines, fitment still depends on your specific configuration.
  • Consult a trusted supplier or Cummins database
    • Providing your ESN allows for accurate confirmation and helps avoid ordering the wrong part.

In short, even if your engine falls within the correct range, the safest way to confirm compatibility is by using your ESN or matching the OEM part number. This ensures proper installation, accurate temperature readings, and reliable engine operation.

A temperature sensor plays a key role in monitoring engine conditions, and while it’s a relatively small component, its lifespan depends on proper maintenance and stable operating conditions. Taking a proactive approach can help prevent premature failure.

The best way to extend its lifespan is to ensure the engine and cooling system are functioning properly, as sensor issues are often caused by external factors rather than the sensor itself.

Here are practical ways to help your temperature sensor last longer:

  • Maintain a healthy cooling system
    • Regularly check coolant levels and condition. Dirty or low coolant can cause overheating, which puts extra stress on the sensor.
  • Avoid engine overheating
    • Consistent overheating can damage the sensor and affect its accuracy over time. Address any cooling issues immediately.
  • Inspect wiring and connections
    • Loose, damaged, or corroded wires can interfere with signal transmission and lead to premature sensor failure.
  • Use the correct coolant type
    • Using the proper coolant helps prevent corrosion and buildup that can affect both the sensor and surrounding components.
  • Address engine issues early
    • Problems like poor combustion or faulty thermostats can create unstable temperature conditions that strain the sensor.
  • Keep up with routine maintenance
    • Regular inspections help catch small issues before they impact the sensor’s performance.

By maintaining stable engine conditions and staying consistent with maintenance, you can help extend the life of your temperature sensor and ensure accurate readings over time.

The 4384577 temperature sensor monitors engine or exhaust temperatures and sends real-time data to the engine control module to support proper system operation.

It can measure exhaust gas or intake-related temperatures depending on installation location, helping the system track thermal conditions accurately.

The data it provides allows the control module to adjust fuel injection timing and other parameters to keep the engine operating within safe temperature limits.

It is widely used on QSB 6.7L and B6.7 engines, along with several other Cummins platforms across different applications.
