SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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.


Give your Cat engine a breath of fresh power with the Caterpillar Diesel Particulate Filter—OEM 20R5620. Engineered to capture soot with superior efficiency, this sturdy DPF preserves clean air flow, helps you pass emissions standards, and keeps your engine running longer and stronger.

Keeping emissions control components working smoothly goes beyond compliance—it's essential for optimal efficiency and uptime. The OEM 20R5620 Diesel Particulate Filter (DPF) plays a key role in maintaining clean exhaust flow, ensuring seamless regeneration, and safeguarding downstream components from soot buildup.

  • Consistent Exhaust Flow for Better Regeneration
    A new OEM 20R5620 ensures consistent exhaust movement and temperature profiles—crucial for effective passive and active regeneration. This helps your system burn off soot naturally without interruption or forced cycles.

  • Protects Aftertreatment Components from Soot Damage
    Efficient filtration prevents soot from penetrating catalytic systems or sensors, reducing wear and protecting the longevity of parts like SCR catalysts and temperature sensors.

  • Minimizes Backpressure and Engine Strain
    Old, clogged DPFs force the engine to work harder and lead to increased fuel consumption. Swapping in the OEM 20R5620 restores proper airflow and reduces stress on engine systems.

  • Direct OEM Fit with Warranty Coverage
    Built to Caterpillar specifications, this DPF installs seamlessly with no modifications. Plus, it's backed by a one-million-mile or one-year warranty—offering assurance in both fit and durability.

  • Easy Core Return for Cost-Effective Maintenance
    The streamlined core charge policy makes servicing simple: return your old unit within the specified timeframe, and you’ll receive a prompt refund—keeping costs down and peace of mind up.

Restoring clean regeneration and minimizing soot accumulation keeps your aftertreatment system healthy and responsive. Trust the OEM 20R5620 DPF from Tamerx Diesel Parts to deliver the precision fit, protection, and reliability your system deserves.

 

The Diesel Particulate Filter (DPF) is a vital emissions component designed to trap and remove soot from a diesel engine’s exhaust. While it may be tempting to continue driving with a faulty DPF, doing so can result in serious consequences—both mechanical and legal. Knowing the risks can help you make a safer and smarter decision when issues arise.

Why Driving with a Faulty DPF Is Risky

A faulty DPF doesn't just affect emissions—it can compromise your engine and vehicle as a whole. Here’s what you need to be aware of:

  • Engine Damage Risk
    A clogged or malfunctioning DPF increases exhaust backpressure, which strains the engine. Over time, this pressure buildup can cause overheating, turbocharger failure, or even engine shutdown.

  • Loss of Power and Efficiency
    You may notice sluggish acceleration, reduced fuel economy, and poor throttle response. These symptoms worsen as the DPF becomes more restricted.

  • Frequent Regeneration or Failure to Regenerate
    A compromised DPF might trigger constant active regeneration cycles or fail to regenerate at all. Both scenarios can stress engine components and reduce lifespan.

  • Check Engine Light and Limp Mode
    Modern diesel vehicles are equipped with monitoring systems that detect DPF issues. Once triggered, your vehicle may enter limp mode, drastically reducing power and speed to prevent damage.

  • Increased Emissions and Legal Penalties
    Driving with a defective DPF can result in excessive smoke, failed emissions tests, and possible fines—especially in regions with strict environmental regulations.

  • Potential Warranty Void
    Ignoring a DPF issue could void warranties related to the engine or emissions system, leading to out-of-pocket repair expenses.

While a faulty DPF may not immediately stop your vehicle from running, the long-term consequences can be severe. Engine damage, performance loss, and legal risks make it crucial to address DPF problems early. If you suspect your DPF is failing, seek diagnostics and service from a trusted technician before the issue escalates. Prompt attention not only protects your vehicle but also ensures compliance with emissions standards.

Frequent idling, low-temperature cycles, or contamination from oil or coolant can degrade the filter more quickly.

Dark soot staining or visible residue around the filter's housing may indicate excessive particulate accumulation.

It can lead to reduced engine efficiency, increased fuel consumption, and activation of fault indicators.

Allow it to cool completely and relieve pressure to avoid handling risks and accidental soot release.
