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 Volvo Mack D13 and MP8 engines (2018–2021 EPA17 models) rely on a precisely engineered Exhaust Gas Recirculation (EGR) system to control emissions. A critical part of this system is the EGR cooler, OEM part number 85136428. Understanding its components helps fleet managers and technicians maintain proper engine operation and emissions compliance.
The primary component is the EGR cooler core, which functions as a heat exchanger. It reduces the temperature of exhaust gases before they are routed back into the intake system. Lower exhaust gas temperatures are essential for controlling nitrogen oxide (NOx) emissions.
In addition to the main cooler assembly, a complete EGR cooler kit may include several supporting components:
- EGR cooler core (heat exchanger assembly)
- Mounting gaskets and seals
- O-rings for coolant passages
- EGR hoses or connecting pipes
- Hose clamps
- Mounting hardware such as bolts and brackets
- Coolant line fittings
The cooler integrates with the engine’s cooling system, allowing coolant to circulate through internal passages to remove heat from exhaust gases. Proper sealing is critical to prevent coolant leaks or exhaust contamination.
When replacing the Volvo Mack D13 or MP8 EGR cooler OEM 85136428, technicians often inspect related hoses and coolant lines to ensure complete system integrity. Using the correct OEM components helps maintain durability and proper emissions system function.
The EGR cooler plays an important role in your diesel engine’s emissions system. It lowers the temperature of exhaust gases before they are recirculated back into the engine. Over time, heat and carbon buildup can cause the cooler to fail.
So when should you replace your EGR cooler?
Most EGR coolers don’t have a set replacement interval. Instead, they should be replaced when symptoms of failure appear or when damage is confirmed during inspection.
Common signs your EGR cooler may need replacement include:
- Unexplained coolant loss
- White exhaust smoke
- Engine overheating
- Rough running or misfire
- Check engine light with EGR-related codes
- Coolant mixing with exhaust gases
Cracks inside the cooler are a frequent cause of failure. Constant heating and cooling cycles put stress on the internal passages. Over time, this can lead to leaks that allow coolant to enter the exhaust system.
High mileage, heavy towing, and poor maintenance can also shorten the life of the component.
If you notice any of these warning signs, it’s important to have the vehicle inspected quickly. Catching an EGR cooler issue early can help prevent more serious engine damage and costly repairs.
Yes, a leaking EGR Cooler can introduce coolant into the exhaust system and lead to operational issues.
Choosing OEM 85136428-EPA17 ensures proper fit and compatibility with factory-equipped emissions components.
The OEM 85136428-EPA17 EGR Cooler cools exhaust gases before they are recirculated back into the engine on Volvo D13 and Mack MP8 EPA17 applications.
