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.

The DEF (Diesel Exhaust Fluid) head unit is a critical part of modern diesel emission systems, monitoring DEF level, temperature, and quality to ensure proper function of the Selective Catalytic Reduction (SCR) system. While designed for long service life, regular maintenance and timely replacement help prevent unexpected failures, costly repairs, and downtime.

Service and Replacement Guidelines for the DEF Head Unit:

  • Follow Manufacturer Recommendations – Most OEMs recommend inspecting the DEF system, including the head unit, during routine maintenance intervals—typically every 6 to 12 months depending on usage.

  • Monitor for Fault Codes – Frequent DEF-related warning lights or fault codes may indicate that service or replacement of the head unit is needed.

  • Inspect During DEF Fluid Changes – Each time DEF is refilled, inspect for signs of crystallization, contamination, or sensor malfunction.

  • Replace After Prolonged Exposure to Extreme Conditions – Vehicles operating in harsh climates (very hot or cold) may require earlier service due to increased wear on electronic components.

  • Consider Replacement After 5 to 7 Years – Many DEF head units may begin to show signs of wear after several years of operation, especially in high-mileage applications.

  • Act Promptly on Performance Issues – If the DEF head unit gives false readings or repeated quality errors, it may be time for immediate replacement.

Regular inspection and timely service of the DEF head unit are key to preventing system failures and maintaining emissions compliance. By following recommended service intervals, monitoring for warning signs, and addressing issues early, you can extend the life of your DEF system and avoid costly downtime.

Failures may result from sensor degradation, electrical faults, or DEF impurities.

System faults may appear, emissions warnings may trigger, and the vehicle may enter a restricted operating mode.

Harsh chemicals, abrasive scrubbing, or high-pressure sprays should be avoided to prevent sensor damage.

It is mounted inside the DEF tank and connects electronically to the emissions control system.
