SHIPPING POLICY
Drive On Diesel 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 Drive On Diesel 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.
Drive On Diesel 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 Drive On Diesel, 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). Drive On Diesel 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 Drive On Diesel, 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 Cummins B6.7 Temp Sensor (OEM 4384573) serves a straightforward but critical purpose: it continuously monitors temperature and feeds that information back to the engine’s control system so adjustments can be made in real time.
Rather than controlling anything directly, its main function is to provide accurate temperature data—which the engine relies on to operate safely and consistently.
Here’s a closer look at what that means:
- Measures temperature at key points
- The sensor tracks heat levels in areas like coolant or exhaust, depending on its placement.
- Sends data to the engine control module (ECM)
- It converts temperature into an electrical signal that the ECM can interpret instantly.
- Helps the ECM make real-time adjustments
- Based on the readings, the system can adjust fuel delivery, timing, or other parameters.
- Prevents overheating or unsafe conditions
- If temperatures rise beyond normal limits, the ECM can trigger protective actions.
- Supports proper emissions system operation
- Many aftertreatment components depend on accurate temperature data to function correctly.
- Enables system alerts and diagnostics
- Abnormal readings can trigger warnings, helping detect issues early.
In simple terms, the Cummins 4384573 temperature sensor acts as the engine’s feedback device, constantly reporting heat levels so the system can respond, adjust, and stay within safe operating conditions.
A temperature sensor plays a crucial role in monitoring engine conditions and sending accurate data to the engine control unit. When it starts to fail, it can cause a range of issues that affect how the engine runs and responds.
Because the sensor influences fuel delivery and cooling system behavior, even small inaccuracies can lead to noticeable problems.
Here are common symptoms of a bad temperature sensor:
- Erratic temperature readings
- The gauge may fluctuate unexpectedly or show readings that don’t match actual engine conditions.
- Check engine light or fault codes
- The system may detect inconsistent or missing data and trigger warning lights.
- Poor fuel efficiency
- Incorrect temperature signals can cause the engine to use more fuel than necessary.
- Hard starting, especially when cold
- The engine may struggle to start if it receives incorrect temperature information during startup.
- Engine overheating or false overheating warnings
- A faulty sensor may fail to detect real overheating or trigger warnings when the engine is operating normally.
- Rough idling or unstable performance
- Improper adjustments based on bad data can cause uneven engine operation.
Addressing a failing temperature sensor early helps maintain accurate system monitoring and prevents further issues with engine performance.
Yes, inaccurate readings can lead to improper control of aftertreatment processes, affecting emissions system efficiency and operation.
