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 Ford Powerstroke 6.7L DOC/DPF (OEM HC3Z-5H270-B) is an integrated emissions-control assembly designed for 2017–2019 Ford Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. This unit combines a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF) into one assembly, allowing it to reduce harmful emissions through multiple stages before exhaust gases leave the vehicle.
Rather than serving a single purpose, this assembly performs two essential emissions-control functions that work together to keep the exhaust system operating efficiently.
What Does the Ford HC3Z-5H270-B DOC/DPF Do?
- Reduces harmful exhaust gases
- The DOC converts carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful substances through a catalytic reaction.
- Captures soot and particulate matter
- The DPF traps fine soot particles produced during combustion, preventing them from being released into the atmosphere.
- Supports automatic regeneration
- As soot accumulates inside the DPF, the system generates the heat needed to burn it off, helping maintain proper filter operation.
- Works with the complete aftertreatment system
- The assembly operates alongside components such as the SCR system, DEF injector, and exhaust sensors to reduce overall emissions.
- Maintains efficient exhaust flow
- By processing exhaust gases through multiple stages, it helps keep the exhaust system functioning smoothly.
- Helps meet emissions regulations
- The combined DOC and DPF assembly plays a major role in reducing both gaseous pollutants and particulate matter, helping the engine comply with modern diesel emissions standards.
The Ford HC3Z-5H270-B DOC/DPF assembly serves as the heart of the engine's exhaust aftertreatment system. The DOC begins the emissions-cleaning process by reducing harmful gases, while the DPF captures soot before it exits the tailpipe. Together, they help produce cleaner exhaust, support downstream emissions components, and contribute to the reliable operation of the entire emissions-control system.
Yes, a faulty DOC/DPF can lead to engine problems if it isn't repaired promptly. Although the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) are part of the emissions system, they have a direct impact on exhaust flow. When either component becomes clogged or damaged, it can create excessive backpressure that affects overall engine operation.
Over time, a restricted DOC/DPF can place additional stress on the engine and other aftertreatment components, leading to reduced efficiency and more extensive repairs.
Here are some of the ways a faulty DOC/DPF can affect your engine:
- Restricted exhaust flow
- A clogged DOC or DPF prevents exhaust gases from exiting efficiently, creating backpressure that forces the engine to work harder than normal.
- Reduced engine responsiveness
- Increased exhaust restriction can result in sluggish acceleration, slower throttle response, and reduced pulling capability, especially under heavy loads.
- Higher fuel consumption
- The engine may use more fuel to compensate for restricted exhaust flow and repeated regeneration attempts.
- Frequent regeneration cycles
- A partially blocked DPF may trigger more frequent regeneration events, placing additional stress on the aftertreatment system.
- Engine derate or limited operating mode
- Many diesel engines will reduce engine output or vehicle speed when serious DOC/DPF faults are detected to help protect the engine and emissions system.
- Additional strain on turbocharger and exhaust components
- Excessive backpressure can increase the workload on the turbocharger and other exhaust system components, potentially leading to premature wear.
- Recurring warning lights and fault codes
- The engine control module may detect abnormal pressure or emissions conditions and trigger diagnostic trouble codes that should not be ignored.
Addressing a faulty DOC/DPF as soon as symptoms appear can help prevent unnecessary engine strain, protect other aftertreatment components, and reduce the likelihood of more costly repairs. Regular maintenance and early diagnosis are the best ways to keep both your engine and emissions system operating reliably.
The system is designed to operate with Ultra-Low Sulfur Diesel (ULSD), which is required to protect the catalyst and particulate filter from premature contamination.
Common indicators include excessive exhaust backpressure, frequent regeneration cycles, DPF efficiency fault codes, warning lights, or visible damage to the aftertreatment housing.
Yes. Excessive soot loading can restrict exhaust flow, reduce aftertreatment efficiency, and increase regeneration frequency if not addressed.
The assembly features a heavy-duty stainless-steel housing that encloses catalyst-coated substrates and a ceramic particulate filter engineered for high-temperature diesel exhaust applications.
