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.

Turbochargers are essential for boosting engine performance and efficiency in modern vehicles. However, like any mechanical component, they can develop problems over time. Diagnosing turbo problems early can prevent further engine damage and ensure your vehicle runs smoothly. Here’s how you can identify issues with your turbocharger.

Turbochargers play a crucial role in enhancing your vehicle's power and efficiency, but they can experience issues that affect performance. Diagnosing turbo problems early can help you address these issues before they lead to more severe damage. Here are some common signs and methods to diagnose turbo problems effectively.

  • Loss of Power

    •  One of the first signs of a turbo problem is a noticeable loss of power. If your vehicle feels sluggish and lacks the usual acceleration, it could indicate that the turbocharger is not providing the necessary boost.

  • Excessive Smoke

    •  If you notice excessive smoke coming from the exhaust, it can be a sign of turbo problems. Blue smoke typically indicates oil leakage, while black smoke suggests that the fuel-air mixture is too rich.

  • Unusual Noises

    • Listen for unusual noises such as whining, grinding, or rattling sounds coming from the turbo area. These sounds can indicate internal damage or wear in the turbocharger components.

  • Check Engine Light

    • The check engine light may illuminate if there are issues with the turbo. An OBD-II scanner can help you read the diagnostic trouble codes (DTCs) to identify the specific problem.

  • Boost Pressure Test

    • Performing a boost pressure test can help determine if the turbocharger is producing the correct amount of boost. Low boost pressure can indicate a problem with the turbo or related components.

  • Inspect Turbo Components

    • Visually inspect the turbocharger and its components for signs of damage or wear. Look for oil leaks, cracks, or other visible issues that could affect the turbo’s performance.

  • Vacuum and Pressure Leaks

    • Check for vacuum and pressure leaks in the turbo system. Leaks can prevent the turbo from building the necessary pressure, leading to reduced performance and efficiency.

  • Oil Condition

    • Examine the condition of the engine oil. Contaminated or degraded oil can affect the turbocharger’s lubrication, leading to increased wear and potential failure. Regular oil changes and using high-quality oil can prevent this issue.

In conclusion, diagnosing turbo problems involves looking for signs such as loss of power, excessive smoke, unusual noises, and the check engine light. Performing boost pressure tests, inspecting turbo components, checking for leaks, and examining the oil condition are essential steps in identifying turbo issues. Addressing these problems early can prevent further damage and ensure your vehicle maintains optimal performance and efficiency. If you suspect turbo problems, consult a professional mechanic for a thorough inspection and necessary repairs to keep your vehicle running smoothly.

Replacing a worn-out turbo restores engine power, improves fuel efficiency, and ensures optimal airflow for better combustion.

A failing turbo can cause reduced acceleration, increased exhaust smoke, poor fuel economy, and potential damage to engine components.

Over-boosting can cause excessive power surges and high exhaust temperatures, while under-boosting leads to sluggish performance and increased emissions.

Yes, damaged turbo seals or bearings can cause oil to leak into the intake or exhaust system, leading to increased oil consumption.
