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 OEM ASP5410-6506711 DEF head unit is a key component in Cummins diesel engines that utilize Selective Catalytic Reduction (SCR) technology. This unit ensures accurate monitoring and delivery of Diesel Exhaust Fluid (DEF), helping maintain system functionality and compliance with emissions standards.
Mounted on top of the DEF tank, the head unit manages critical functions such as fluid level detection, temperature monitoring, and routing DEF to the dosing module. If malfunctioning, it can trigger warning codes or system derates, making timely replacement essential.
Key features of the OEM ASP5410-6506711 DEF head unit include:
- Level Sensor Integration
- Sends accurate fluid level readings to the ECM
- Heater Element
- Protects against DEF crystallization in cold conditions
- Temperature Sensor
- Enables proper DEF dosing performance
- OEM Electrical Connector
- Ensures reliable connection with Cummins systems
- Standard Tank Mounting Flange
- Simplifies installation and replacement
Always verify your engine application and match the OEM number (ASP5410-6506711) to ensure correct fit and function.
This unit is ideal for medium- and heavy-duty Cummins-powered trucks, buses, and equipment operating in regulated environments.
The DEF (Diesel Exhaust Fluid) head unit—often referred to as the DEF header—is a key part of the emissions system in modern diesel vehicles. It ensures accurate monitoring and operation of the DEF tank, which is critical for the Selective Catalytic Reduction (SCR) system.
Main Functions of the DEF Head Unit:
- Measure DEF Fluid Level
- It uses an internal sensor to monitor how much DEF is in the tank and communicates that data to the vehicle’s computer.
- Monitor Fluid Temperature
- The unit tracks DEF temperature to detect freezing or overheating conditions that can interfere with fluid flow.
- Activate Internal Heater
- In cold conditions, it turns on a built-in heater to thaw the fluid and keep it usable.
- Send Data to the Engine Control Module (ECM)
- It transmits real-time information on DEF level and temperature so the system can inject the correct amount into the exhaust stream.
Without a functioning DEF head unit, the SCR system cannot confirm whether emissions are being properly treated. This can lead to warning lights, reduced driving limits, and eventually force the vehicle into restricted operation to stay emissions-compliant.
Yes, it is built to withstand DEF crystallization and includes a heating element to keep the fluid from freezing.
No programming is required, but fault codes should be cleared and sensor readings verified using diagnostic tools.
It should be inspected during scheduled emissions system maintenance or if DEF-related faults occur.
Yes, incorrect installation may result in suction issues or leaks that can disrupt proper DEF flow.
