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 turbo actuator is a key control component within the turbocharging system of heavy-duty diesel engines. In Cummins X12 and QSX15 applications, this unit manages how the turbocharger responds to engine demand by adjusting airflow and boost pressure. By working directly with the engine control module (ECM), the actuator helps ensure the turbo operates within the correct range for efficient and stable engine operation.

  • Controls Turbo Boost Pressure
    The actuator regulates how much boost the turbocharger produces by adjusting internal components like vanes or wastegate position, helping prevent over-boost or underperformance.
  • Optimizes Airflow Based on Engine Demand
    By responding to signals from the ECM, the actuator adjusts airflow in real time, ensuring the engine receives the right amount of compressed air at different speeds and loads.
  • Supports Smooth Power Delivery
    Proper actuator function helps maintain consistent turbo response, reducing lag and supporting steady acceleration during varying driving conditions.
  • Designed for Cummins X12 and QSX15 Engines
    This actuator is built for compatibility with Cummins X12 and QSX15 engines from 2018 to 2024, aligning with the turbo system used in these heavy-duty platforms.
  • Essential for Turbocharger System Efficiency
    The actuator plays a major role in balancing power output, fuel usage, and emissions by ensuring the turbocharger operates within its intended parameters.

The turbo actuator is a vital part of maintaining proper turbocharger function in diesel engines. For Cummins X12 and QSX15 applications, a reliable actuator helps ensure controlled boost, stable engine response, and consistent operation across demanding workloads.

A turbo actuator plays an important role in controlling boost pressure by regulating the turbocharger’s internal components. Whether electronically or vacuum controlled, the actuator ensures the turbo operates within proper limits. When a turbo actuator fails, it can lead to reduced power, poor fuel efficiency, and fault codes. Understanding the common causes of turbo actuator failure can help prevent unexpected downtime.

  • Excessive heat is one of the most common causes. Turbochargers operate in high-temperature environments, and prolonged exposure can damage internal actuator components or electronics.

  • Carbon buildup and soot accumulation can restrict movement inside the turbo mechanism. When the actuator cannot move the vanes or wastegate freely, it may become stuck or overworked.

  • Electrical issues such as damaged wiring, corroded connectors, or failed internal motors can prevent electronic actuators from responding correctly.

  • Moisture intrusion can affect both electronic and vacuum-style actuators. Water contamination may lead to corrosion or internal component failure.

  • Lack of regular maintenance, including delayed oil changes, can contribute to turbo-related wear that places added strain on the actuator.

  • Overboost or underboost conditions caused by sensor problems may force the actuator to constantly compensate, leading to premature wear.

Turbo actuator failure can impact overall engine performance and trigger warning lights. Addressing boost-related issues early, maintaining proper service intervals, and ensuring clean oil and air systems can help extend the life of both the turbocharger and its actuator.
