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.

When your emissions system throws DEF-related errors, don’t overlook the DEF head unit. The Cummins OEM ASP5410-6506722 helps ensure proper operation and accurate DEF readings. Choose TamerX Diesel Parts for OEM-grade components that help keep your engine running smoothly and in compliance.

 

The DEF (Diesel Exhaust Fluid) head unit is responsible for monitoring DEF level, quality, and temperature—critical functions for maintaining emissions compliance in diesel engines. Since the DEF head is directly exposed to varying environmental and operating temperatures, extreme heat or cold can impact its performance and reliability. Understanding these effects can help you take preventive steps and reduce downtime.

Ways Temperature Impacts the DEF Head Unit:

  • Freezing Temperatures – DEF begins to freeze at 12°F (-11°C), which can lead to crystal buildup around the sensors and inside the DEF head unit, impairing sensor accuracy or function.

  • Sensor Lag in Cold Conditions – Extremely low temperatures can delay sensor response time, causing inaccurate DEF level or quality readings.

  • Overheating Risks – High ambient or under-hood temperatures can damage the electronic components in the DEF head or degrade plastic housing.

  • Crystallization from Temperature Fluctuations – Repeated freezing and thawing cycles can lead to crystal deposits that interfere with fluid flow or clog sensors.

  • Check Engine Lights or Derates – Temperature-related sensor errors may trigger warning lights or cause the system to restrict engine power.

  • Accelerated Component Wear – Continuous exposure to extreme heat or cold can shorten the life of the DEF head unit and related wiring.

Temperature has a direct impact on the performance and durability of the DEF head unit. To reduce the risk of failure, use proper DEF storage practices, perform regular inspections, and ensure your DEF system is protected in extreme weather. Managing temperature-related risks helps maintain emission compliance and prevents costly breakdowns.

It ensures accurate DEF monitoring, which is essential for the SCR system to maintain EPA emission standards.

Incorrect readings can lead to engine derate or warning alerts due to perceived DEF issues.

A fault is usually indicated by DEF system warning lights, trouble codes, or erratic fluid level data.

Yes, contaminated DEF can cause sensor malfunctions or incorrect fluid quality readings.
