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.

The Cummins ISL-400 Turbo Assembly (OEM 4025398) is a crucial component that helps optimize engine performance by increasing airflow to the engine’s combustion chamber. Turbochargers play a vital role in improving fuel combustion, ensuring greater engine efficiency, and reducing emissions. In this blog, we’ll explore the function of the turbo assembly and offer practical maintenance tips to keep it in peak condition for long-term engine performance.

Key Functions of the Cummins ISL-400 Turbo Assembly:

  • Boosted Airflow
    • The turbocharger compresses air entering the engine, allowing for more oxygen to be available for combustion. This results in improved fuel combustion and overall engine performance.
  • OEM Quality
    • As a genuine Cummins part (OEM 4025398), this turbo assembly ensures durability, optimal fit, and compatibility with Cummins ISL-400 engines from 2001 to 2004.
  • Improved Fuel Efficiency
    •  By increasing the amount of air entering the combustion chamber, the turbo helps the engine run more efficiently, reducing fuel consumption.

Maintenance Tips for Cummins ISL-400 Turbo Assembly:

  • Inspect for Leaks
    •  Regularly check for any oil or air leaks around the turbocharger. Leaks can reduce turbo efficiency and lead to engine issues over time.
  • Keep Air Filters Clean
    • Ensure that the air filters are regularly cleaned or replaced to prevent debris from entering the turbo, which can cause significant damage.
  • Listen for Unusual Noises
    •  If you hear any whistling or grinding sounds coming from the turbo, it could be an early sign of malfunction. Address these issues immediately to prevent further damage.
  • Allow Proper Cool-Down
    • After long drives or heavy engine loads, allow the engine to idle for a few minutes before shutting it off. This practice ensures the turbo cools down gradually, preventing heat-related damage.

The Cummins ISL-400 Turbo Assembly (OEM 4025398) is essential for increasing engine airflow, enhancing combustion, and improving fuel efficiency. With proper maintenance practices such as inspecting for leaks, keeping air filters clean, and monitoring for unusual sounds, you can extend the life of your turbocharger and ensure your engine continues to perform optimally. Trust TamerX Diesel Parts for high-quality OEM components to keep your Cummins ISL-400 engine running at its best.

 

The turbo assembly in your diesel engine is crucial for boosting power and fuel efficiency by increasing the air intake into the engine’s combustion chamber. When the turbo assembly fails, it can lead to a range of engine problems that affect performance, fuel economy, and overall reliability. Understanding the consequences of a failed turbo assembly can help you take action early to prevent further damage.

Effects of a Failing Turbo Assembly

  • Loss of Power

    • A failing turbo can cause a significant drop in engine power, leading to sluggish acceleration and reduced overall performance, especially when towing or climbing hills.

  • Excessive Exhaust Smoke

    • If the turbo assembly fails, it can lead to oil leaking into the exhaust system, which results in thick, dark smoke. This is a common sign of turbo failure.

  • Increased Fuel Consumption

    • Without a functioning turbo, your engine must work harder to produce power, leading to higher fuel consumption and decreased fuel efficiency.

  • Loud Whining Noise

    • A failing turbo often produces a loud whining or whistling noise during acceleration, indicating internal damage to the turbo’s components.

  • Engine Overheating

    • A damaged turbo can cause increased engine temperatures due to reduced airflow, which can lead to overheating and potential engine damage if left unaddressed.

  • Check Engine Light

    • A malfunctioning turbo assembly can trigger the check engine light, signaling a problem with the turbocharger or related components.

A failed turbo assembly can lead to power loss, increased fuel consumption, and potential engine damage. Recognizing the symptoms early, such as excessive smoke, unusual noises, or a loss of power, can help you address the issue before it worsens. Regular maintenance and timely repairs are essential to keep your diesel engine running efficiently and prevent costly damage. If you suspect a problem with your turbo assembly, it’s important to consult a professional mechanic immediately.
