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 Hino J08E 7.7L EGR Valve (OEM 25608E007) works as a controlled gateway that manages the flow of exhaust gases back into the engine’s intake system. This process is part of the Exhaust Gas Recirculation (EGR) system, which helps regulate combustion conditions and reduce emissions.
Instead of allowing all exhaust gases to exit, the EGR valve redirects a measured portion back into the intake. This recirculated gas mixes with fresh air, lowering the oxygen concentration and reducing combustion temperatures.
Here’s how it works step by step:
- Receives signals from the engine control unit (ECU)
- The ECU determines when and how much exhaust gas should be recirculated based on engine load, speed, and temperature.
- Opens and closes to regulate flow
- The valve adjusts its position to allow a specific amount of exhaust gas to re-enter the intake system.
- Redirects exhaust gases into the intake manifold
- These gases mix with incoming air before entering the combustion chamber.
- Lowers combustion temperature
- The presence of exhaust gas reduces peak temperatures during combustion, which helps limit the formation of nitrogen oxides (NOx).
- Continuously adjusts during operation
- The valve constantly changes position in real time to match engine demands and maintain proper balance.
- Closes under certain conditions
- During cold starts or heavy acceleration, the valve may remain closed to ensure proper engine operation.
In simple terms, the Hino 25608E007 EGR valve works by carefully controlling how much exhaust gas is reintroduced into the engine, helping regulate temperature and reduce harmful emissions while maintaining smooth operation.
An EGR (Exhaust Gas Recirculation) valve doesn’t follow a fixed replacement schedule, so it should be replaced based on its condition and how it’s performing. Over time, carbon buildup and wear can prevent it from functioning properly.
The best time to replace your EGR valve is when it becomes stuck, clogged, or unable to regulate exhaust flow effectively. Ignoring the warning signs can lead to more noticeable engine issues.
Here are common indicators that it may be time for a replacement:
- Persistent rough idling or stalling
- If the valve is stuck open or closed, it can disrupt the air-fuel mixture and cause unstable engine operation.
- Check engine light or EGR-related fault codes
- Diagnostic alerts often point to improper EGR flow or valve malfunction.
- Reduced fuel efficiency
- Improper exhaust gas recirculation can lead to inefficient combustion and increased fuel usage.
- Hesitation or poor acceleration
- The engine may struggle to respond smoothly due to incorrect airflow balance.
- Excessive carbon buildup
- If cleaning no longer restores proper function, replacement is usually necessary.
Routine inspection and occasional cleaning can extend the valve’s life, but once it consistently fails to operate correctly, replacing it is the most reliable solution.
Soot buildup can restrict valve movement or clog passages, reducing its ability to control exhaust gas flow effectively.
It typically uses an electronically controlled actuator that allows precise adjustment based on signals from the engine control system.
Yes, improper EGR flow can cause rough idling or unstable engine operation due to incorrect air-to-gas ratios.
It is sealed using gaskets and mounting hardware to prevent leaks between the exhaust and intake systems.
