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.

Service and Replacement Guidelines for a DEF Head Unit:

  • Follow OEM Maintenance Schedules – Most manufacturers recommend inspecting the DEF system, including the head unit, during regular service intervals, typically every 6 to 12 months.

  • Monitor Warning Lights and Fault Codes – Frequent DEF system errors, incorrect readings, or warning lights may signal the need for service or replacement.

  • Inspect During DEF Refills – Look for signs of crystallization or contamination around the tank and head unit when refilling DEF.

  • Consider Replacement After High Mileage – Many DEF head units begin to show signs of wear after 5 to 7 years or in high-mileage vehicles.

  • Harsh Operating Conditions – Vehicles exposed to extreme temperatures, heavy-duty use, or poor DEF quality may require more frequent inspection or earlier replacement.

  • Sensor Malfunctions – Inconsistent DEF level, quality, or temperature readings may indicate sensor wear inside the head unit, requiring replacement.

Regular inspection and proactive service are the keys to maximizing the life of your DEF head unit. Staying ahead of sensor wear, contamination, and system faults helps maintain emissions compliance, reduces downtime, and protects your engine’s performance. When in doubt, consult your manufacturer’s guidelines and address any DEF system warnings promptly.

The unit measures DEF fluid level, urea concentration, and temperature continuously.

Contamination, sensor degradation, electrical issues, or software errors can interfere with accurate readings.

Its integrated quality sensor measures urea concentration to ensure fluid consistency meets required standards.

Warning lights, fault codes, inaccurate fluid readings, or reduced engine power may indicate failure.
