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.

The DEF (Diesel Exhaust Fluid) head unit is a key component of the diesel emissions system, ensuring that DEF is properly monitored and delivered to reduce harmful NOx emissions. Understanding the various components that make up a DEF head unit can help in diagnosing issues, performing maintenance, and ensuring reliable system operation.

Main Components of a DEF Head Unit:

  • Level Sensor – Monitors the amount of DEF fluid in the tank and sends data to the engine control module (ECM) to ensure proper dosing.

  • Temperature Sensor – Measures the DEF temperature to prevent freezing or overheating and adjusts dosing as needed.

  • Quality Sensor – Checks the concentration of urea in the DEF to ensure it meets the required standards for proper emissions control.

  • Suction Tube/Standpipe – Draws DEF fluid from the tank and delivers it to the pump for injection into the exhaust stream.

  • Heating Element – Prevents DEF from freezing in cold temperatures, ensuring consistent fluid delivery even in harsh conditions.

  • Electrical Connectors and Wiring – Provide power and communication between the DEF head unit and the vehicle’s ECM.

  • Seals and Gaskets – Prevent contamination, leaks, and moisture intrusion into the DEF system and sensor components.

The DEF head unit is a compact yet complex assembly that plays a critical role in emissions compliance. Each component works together to monitor and manage DEF fluid properly. Regular inspection and proper maintenance help ensure these components continue functioning as intended, keeping your emissions system running efficiently and reliably.

Sensor aging, contamination, or electrical disruptions may cause inaccurate DEF data.

It verifies urea concentration levels to confirm that DEF meets required chemical standards for emissions compliance.

System errors, DEF warning lights, and inconsistent fluid level or quality readings may indicate failure.

DEF crystallization can cover sensor elements and obstruct accurate fluid monitoring.
