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 customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Engine Control Module (ECM) is a vital component of your vehicle’s engine management system, responsible for controlling various functions such as fuel injection, ignition timing, and emissions. When the ECM fails, it can lead to a range of engine performance issues and potentially costly repairs. Understanding what causes an ECM to fail can help you take preventive measures to keep your vehicle running smoothly. In this blog, we’ll explore the common factors that can lead to ECM failure.

  • Electrical Overloads

    •  One of the most common causes of ECM failure is an electrical overload. This can happen if there is a short circuit, a faulty wiring harness, or an issue with the vehicle’s battery or alternator. Excessive voltage can damage the ECM’s internal components, leading to malfunction.

  • Water Damage

    •  The ECM is typically located in the engine bay or inside the vehicle, but it’s still vulnerable to water damage if the area where it’s housed isn’t properly sealed. Water or moisture entering the ECM can cause corrosion of its circuits, leading to failure.

  • Extreme Temperatures

    • ECMs are designed to withstand a certain range of temperatures, but extreme heat or cold can cause the unit to fail. Prolonged exposure to high temperatures, especially in poorly ventilated engine bays, can lead to overheating and damage to the ECM’s internal components.

  • Vibration and Shock

    •  Constant vibration and shock from the engine or road conditions can cause wear and tear on the ECM. Over time, this can lead to loose connections or even damage to the internal circuits of the module.

  • Faulty Sensors

    • The ECM relies on various sensors to monitor engine performance and make adjustments. If a sensor fails or sends incorrect data, it can cause the ECM to malfunction. In some cases, a faulty sensor can even cause the ECM to fail entirely if the problem is not addressed.

  • Age and Wear

    •  Like any electronic component, the ECM can wear out over time. Prolonged use, combined with exposure to heat, vibration, and electrical fluctuations, can lead to the gradual degradation of the ECM, eventually resulting in failure.

Understanding the causes of ECM failure is key to preventing unexpected engine issues and maintaining your vehicle’s performance. By being aware of factors such as electrical overloads, water damage, and extreme temperatures, you can take steps to protect your ECM and extend its lifespan. Regular inspections and addressing any sensor issues promptly can also help prevent ECM failure. Keeping your ECM in good working order is essential for ensuring your vehicle runs smoothly and reliably.

Yes, a replacement ECM must be programmed to match your truck’s specifications, which should be done using Mack-approved diagnostic tools.

Yes, a failing ECM can cause the check engine light, ABS light, or other system warnings to appear due to miscommunication with vehicle sensors.

A diagnostic scan tool can help detect ECM-related fault codes, and testing voltage at the ECM connectors can confirm power supply issues.

In some cases, disconnecting the battery for a few minutes or using a diagnostic tool to clear error codes may reset the ECM, but deeper issues require reprogramming or replacement.
