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 Mercedes MBE904 EGR Cooler (OEM 9041420479) is an essential component of your diesel engine’s exhaust gas recirculation (EGR) system. Designed to reduce harmful emissions and improve engine efficiency, the EGR cooler plays a crucial role in regulating the temperature of exhaust gases before they re-enter the combustion chamber.

Why the EGR Cooler Matters

The EGR cooler is vital for maintaining optimal engine performance and reducing emissions. Here’s how this part benefits your vehicle:

  • Reduces NOx Emissions
    • By cooling the exhaust gases before they are recirculated back into the engine, the EGR cooler helps reduce nitrogen oxide (NOx) emissions, keeping your vehicle compliant with emission standards.
  • Improves Engine Efficiency
    • By lowering the combustion temperature, the EGR cooler prevents engine knocking and promotes more efficient combustion.
  • Prevents Overheating
    •  The cooler helps manage the engine’s temperature, reducing the risk of overheating and prolonging engine life.
  • Enhances Fuel Efficiency
    • A well-functioning EGR system ensures the engine runs more smoothly, which can improve fuel economy.

Key Maintenance Tips for Your Mercedes MBE904 EGR Cooler

To ensure your OEM 9041420479 EGR cooler stays in top condition, follow these maintenance practices:

  • Regular Cleaning
    • Over time, carbon buildup can clog the EGR cooler, reducing its efficiency. Regular cleaning prevents blockages and maintains optimal performance.
  • Check for Leaks
    •  Inspect the cooler for any signs of coolant or exhaust leaks, which can indicate damage or wear.
  • Monitor Engine Temperatures
    • Keep an eye on your engine's temperature gauge. Sudden increases can signal an issue with the EGR system or cooler.
  • Replace Damaged Components
    •  If you notice decreased fuel efficiency or increased emissions, it may be time to replace the EGR cooler or associated parts.
  • Scheduled Inspections
    • Include the EGR cooler in your routine maintenance checks to catch potential problems early.

The Mercedes MBE904 EGR Cooler (OEM 9041420479) is critical for reducing emissions and improving engine efficiency. Regular maintenance and timely replacements will ensure that your engine runs smoothly and stays compliant with emissions standards. For high-quality EGR coolers and other diesel engine parts, TamerX Diesel Parts offers reliable solutions to keep your engine performing at its best.

The EGR (Exhaust Gas Recirculation) cooler is an essential part of your vehicle's emission control system, responsible for cooling exhaust gases before they are recirculated into the engine. A malfunctioning EGR cooler can lead to various engine problems and decreased performance. In this blog, we’ll explore the key symptoms of a bad EGR cooler and how to recognize when it's time for a replacement.

Signs of a Bad EGR Cooler

  • Excessive White Smoke from the Exhaust

    • One of the most obvious signs of a bad EGR cooler is white exhaust smoke. This is often caused by coolant leaking into the exhaust system due to a cracked or damaged EGR cooler.

  • Engine Overheating

    • A failing EGR cooler can cause your engine to overheat. This occurs because the cooler is no longer able to effectively cool the exhaust gases, leading to higher engine temperatures.

  • Loss of Coolant Without Visible Leaks

    •  If you're noticing that your coolant levels are dropping but can't find any visible leaks, the EGR cooler could be the culprit. Coolant may be leaking internally into the engine or exhaust system.

  • Reduced Engine Performance:

    • A malfunctioning EGR cooler can lead to reduced engine performance. You might experience sluggish acceleration, poor fuel efficiency, or a lack of overall power.

  • Check Engine Light

    • A failing EGR cooler may trigger the check engine light, alerting you to a problem within the system. While this light can indicate a variety of issues, it’s essential to have it checked promptly to determine if the EGR cooler is at fault.

  • Rough Idling or Engine Misfires

    • A damaged EGR cooler can cause the engine to idle roughly or misfire due to improper recirculation of exhaust gases. This can lead to an unstable engine at low speeds.

  • Coolant in the Exhaust System: If you detect the smell of coolant in the exhaust system or see wet spots near the tailpipe, it’s a sign that the EGR cooler is leaking coolant into the exhaust.

Recognizing the signs of a bad EGR cooler early on can prevent more serious engine damage and costly repairs. If you notice white smoke, engine overheating, coolant loss, or poor performance, it may be time to replace your EGR cooler. At TamerX Diesel Parts, we offer high-quality EGR coolers to keep your engine running efficiently and reduce harmful emissions. Don’t wait for the problem to worsen—address EGR cooler issues promptly for optimal vehicle performance.
