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 Cummins 3.9 Turbo Assembly, particularly the OEM 4089319RX model, is a crucial part of the engine system for many vehicles from 2008 to 2011. Understanding its components can help ensure smoother engine operation and identify potential issues before they become major problems.
The turbo assembly includes several key parts that work together to increase engine efficiency by boosting air intake. Here are the primary components of the Cummins 3.9 Turbo Assembly:
- Compressor Wheel
- This part helps compress the incoming air, allowing more oxygen to enter the combustion chamber.
- Turbine Wheel
- Driven by exhaust gases, the turbine wheel powers the compressor to increase air pressure.
- Center Housing
- This connects the compressor and turbine, housing the bearings and oil passages.
- Wastegate
- Regulates the boost pressure to prevent overloading the engine.
- Actuator
- Controls the wastegate, managing airflow and pressure.
Regular maintenance and timely replacements of these components are essential to prolong the life of your turbo system. If you’re experiencing issues with your Cummins 3.9 Turbo Assembly, it may be time to inspect these parts to ensure your engine remains reliable on the road.
A bad turbo assembly can lead to significant engine damage if not addressed promptly. The turbocharger is a vital component that boosts the engine's power by increasing the air intake, which in turn improves combustion. When the turbo assembly fails, it can disrupt this balance, causing a range of issues that may affect the engine’s overall health.
Here are some potential consequences of a bad turbo assembly:
- Reduced airflow
- A malfunctioning turbo can lead to insufficient air supply, causing the engine to work harder than it should.
- Oil contamination
- When the seals within the turbo fail, oil can leak into the exhaust system, which may eventually damage engine components.
- Increased exhaust temperatures
- A failing turbo may cause the engine’s exhaust gases to rise, leading to overheating and potential engine wear.
- Loss of power
- Without the turbo functioning properly, the engine may lose power, making it struggle to maintain normal operation.
If left unresolved, a faulty turbo assembly can lead to more expensive repairs, including damage to pistons, valves, and other key components. Regular maintenance and early detection of issues can help prevent costly engine damage. If you suspect issues with your turbo, it's essential to seek professional assistance as soon as possible.
Signs include blue or black exhaust smoke, reduced engine response, high oil consumption, or abnormal whining or scraping noises.
This can result from intake or charge air leaks, clogged air filters, or a mismatch between turbo sizing and engine load conditions.
With clean oil, good filtration, and correct installation, the turbo can operate reliably for thousands of hours in typical off-highway or truck use.
A whistling sound is often due to intake or exhaust leaks at flange joints, loose clamps, or cracked piping near the turbo.
