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 Paccar MX11 Exhaust Brake (OEM 2459924PE) is an important component designed to assist in slowing down the vehicle by using engine compression rather than relying solely on the service brakes. Commonly used in 2013–2024 engines, it enhances control during deceleration, especially in heavy-duty applications.

Instead of traditional braking, the exhaust brake works by restricting the flow of exhaust gases. This creates back pressure in the engine, which helps slow the rotation of the engine and, in turn, the vehicle.

Here are the main functions of this exhaust brake:

  • Provides additional braking force
    • By restricting exhaust flow, the system creates resistance within the engine, helping reduce vehicle speed without constant use of the brake pedal.
  • Reduces wear on service brakes
    • Using the exhaust brake during deceleration helps minimize reliance on traditional braking systems, extending the life of brake components.
  • Improves control on downhill grades
    • It allows for better speed management when descending slopes, reducing the risk of overheating the primary braking system.
  • Enhances overall driving safety
    • The added braking capability gives drivers more control in heavy-load or demanding driving conditions.
  • Works seamlessly with engine controls
    • The system is activated electronically and integrates with the engine’s operation to provide smooth and controlled deceleration.
  • Supports consistent braking performance
    • Unlike friction brakes that can fade with heat, the exhaust brake provides steady resistance during prolonged use.

In simple terms, the Paccar MX11 exhaust brake functions as an engine-assisted braking system, helping slow the vehicle safely while reducing strain on traditional braking components.

A failing exhaust brake can reduce your ability to control speed, especially when driving downhill or carrying heavy loads. Since this component helps manage engine braking, it’s important to address any issues early to maintain safe operation.

The first step is identifying what’s causing the failure. Exhaust brake problems are often related to buildup, actuator issues, or restricted movement within the system.

Here are the steps you should take:

  • Inspect for carbon buildup
    • Over time, soot and carbon deposits can accumulate inside the exhaust brake, causing it to stick or not close properly. Cleaning may help restore function if caught early.
  • Check actuator operation
    • The actuator controls the movement of the exhaust brake. If it’s not responding correctly due to electrical or mechanical issues, the brake won’t engage as intended.
  • Look for wiring or connection issues
    • Damaged wires or loose connections can interrupt communication between components, preventing proper activation.
  • Verify proper movement of internal components
    • Make sure the valve or mechanism inside the exhaust brake is moving freely without restriction or resistance.
  • Run a diagnostic scan
    • Fault codes can help identify whether the issue is sensor-related, mechanical, or tied to another system.

If the problem persists after inspection and cleaning, replacement of worn or damaged components may be necessary. Addressing the issue early helps maintain proper braking control and prevents additional strain on your vehicle.

In addition to long-haul trucks, it is used in industries like construction, agriculture, and vocational fleets where Cummins X15 engines are installed.

Yes, proper operation ensures stable exhaust conditions, which allows sensors downstream to receive accurate data for system monitoring.

It is positioned at the beginning of the aftertreatment system and initiates the chemical processes that prepare exhaust gases for further treatment by other components.

Yes, it is designed as a replaceable unit within the aftertreatment system and can be serviced independently from other components.
