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 Engine Control Module (ECM) is the brain of any modern diesel engine, controlling critical functions that ensure optimal engine performance. In the Caterpillar 3126 engine, the OEM 209-9587 ECM is responsible for managing fuel injection, engine timing, and other vital processes. Understanding how this part works and why it’s essential for your engine is key to keeping your equipment running smoothly.

Key Functions of the Caterpillar 3126 Engine Control Module (OEM 209-9587):

  • Controls Fuel Injection

    • The ECM precisely controls the fuel injection process, ensuring the correct amount of fuel is delivered to the engine at the right time. This leads to efficient combustion and better fuel economy.

  • Manages Engine Timing

    • Engine timing is crucial for ensuring smooth operation. The ECM adjusts the timing based on various engine parameters, which helps optimize performance and reduce engine stress.

  • Monitors Engine Health

    • The ECM constantly monitors engine conditions, such as temperature, pressure, and load. It uses this data to make real-time adjustments, ensuring the engine operates within safe parameters.

  • Supports Diagnostic Capabilities

    • When there’s a problem with the engine, the ECM logs fault codes that can be used for diagnostics. This helps mechanics quickly identify and fix issues, reducing downtime and repair costs.

  • Improves Emission Control

    • By managing fuel injection and engine timing, the ECM helps the engine run more efficiently and with fewer emissions. This is especially important for meeting environmental regulations.

  • Enhances Engine Longevity

    • Proper control of the engine’s functions reduces wear and tear on engine components, extending the overall lifespan of the engine.

The Caterpillar 3126 Engine Control Module (OEM 209-9587) is a vital part of your engine, responsible for controlling key functions like fuel injection and engine timing. Keeping your ECM in top condition ensures that your Caterpillar 3126 engine runs efficiently and reliably. At TamerX Diesel Parts, we offer high-quality OEM ECMs to help maintain the performance and longevity of your engine.

The Engine Control Module (ECM) serves as the brain of your vehicle’s engine, managing various critical functions like fuel injection, ignition timing, and emissions control. When the ECM begins to fail, it can lead to a range of issues that affect your vehicle’s performance, fuel efficiency, and drivability. Identifying the symptoms of a bad ECM early on can help prevent further damage and ensure your engine runs smoothly. In this blog, we’ll explore the key signs of a failing ECM.

Symptoms of a Bad Engine Control Module:

  • Check Engine Light

    • One of the most common signs of a bad ECM is the check engine light appearing on your dashboard. While the light can indicate various issues, a malfunctioning ECM is often one of the causes, especially if other symptoms accompany it.

  • Engine Stalling or Misfires

    • A failing ECM may struggle to manage engine functions properly, leading to random stalling, misfires, or hesitation during acceleration. This can make the vehicle difficult to drive and unreliable.

  • Poor Fuel Efficiency

    • When the ECM malfunctions, it can disrupt the air-fuel mixture, resulting in poor combustion. This often leads to a noticeable drop in fuel efficiency, causing your vehicle to consume more fuel than usual.

  • Difficulty Starting the Engine

    • If the ECM is failing, it may have trouble sending the correct signals to the engine. This can result in difficulty starting the vehicle or prolonged cranking times before the engine turns over.

  • Unpredictable Engine Performance

    • A malfunctioning ECM can cause erratic engine performance, such as sudden power loss, hesitation, or surges while driving. These unpredictable behaviors are often signs that the ECM is not regulating the engine correctly.

  • Transmission Problems

    •  In vehicles with automatic transmissions, a faulty ECM can interfere with smooth shifting. You may notice rough or delayed gear changes, as the ECM plays a role in coordinating engine and transmission functions.

  • Failure to Start

    • In severe cases, a completely failed ECM may prevent the engine from starting altogether. Without proper signals from the ECM, the engine may not receive the fuel or spark it needs to start and run.

A bad engine control module can cause a wide range of issues, including engine stalling, poor fuel efficiency, starting problems, unpredictable performance, and even transmission issues. Recognizing these symptoms early and having your vehicle inspected by a professional can prevent further engine damage and costly repairs. Regular maintenance and addressing warning signs promptly will help ensure that your engine control module remains functional, keeping your vehicle running efficiently and reliably.
