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.

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.

Maintaining stable engine temperatures in John Deere machines (2011–2018) is a mission-critical task—and the OEM DZ101012 EGR cooler is a key player in that system. Built to the original equipment specifications, this part efficiently cools recirculated exhaust gases before they return to the engine, helping to moderate internal temperatures and protect vital components from thermal damage.

  • Precision Temperature Management
    The OEM DZ101012 EGR cooler keeps exhaust gasses cool before re-entry into the combustion chamber. By reducing the thermal load, it shields engine components from excessive heat, boosting operational longevity.

  • Prevents Overheating and Related Damage
    A compromised or clogged EGR cooler can lead to overheating, causing temperature spikes that may damage the engine or trigger protective shut-downs.

  • Minimizes Coolant Intrusion Risks
    If the cooler develops internal cracks or degradation, coolant may enter the exhaust stream—leading to unexplained coolant loss, white steam exhaust, or even internal engine harm. The OEM build quality ensures integrity tight enough to guard against such failures.

  • Maintains Emissions Compliance
    By effectively cooling recirculated exhaust, the OEM cooler contributes to cleaner combustion and helps the overall EGR system manage NOx emissions more efficiently.

  • Reliable OEM Fit for Hassle-Free Replacement
    Engineered to match original specifications, the OEM DZ101012 fits seamlessly into John Deere 2011–2018 applications. Its accurate fit means faster service, fewer adjustments, and confidence in quality—and it's backed by a generous warranty and straightforward core return process for easy, cost-effective service.

If you want your John Deere machine to stay cool, efficient, and reliable, the OEM DZ101012 EGR cooler deserves your attention. Its critical role in managing exhaust-temperature recirculation makes it more than just a part—it’s a safeguard against overheating, emissions issues, and costly downtime. Choose OEM accuracy and durability from Tamerx Diesel Parts, and keep your engine’s combustion on a steady, safe path.

Yes, a clogged Exhaust Gas Recirculation (EGR) cooler can contribute to engine overheating. The EGR cooler plays an essential role in reducing combustion temperatures by reintroducing cooled exhaust gases back into the engine. When it becomes restricted or clogged with carbon deposits, it disrupts the engine's thermal balance, leading to performance issues and potential overheating.

Why the EGR Cooler Matters

The EGR cooler is designed to lower the temperature of recirculated exhaust gases before they re-enter the combustion chamber. This process reduces nitrogen oxide (NOx) emissions and helps the engine run at a controlled temperature. When the EGR cooler gets clogged, this vital function is compromised.

Signs and Effects of a Clogged EGR Cooler

  • Increased Engine Temperatures
    A blocked EGR cooler limits exhaust gas flow, reducing the cooling effect and potentially causing the engine to run hotter than normal.

  • Coolant Leaks or Loss
    If the cooler is damaged or cracked due to clogging and pressure buildup, it may leak coolant internally or externally, contributing to overheating.

  • Illuminated Warning Lights
    A clogged cooler often triggers the check engine light due to irregular EGR flow or coolant temperature sensors detecting abnormal readings.

  • Poor Engine Performance
    Restricted exhaust flow can lead to power loss, misfires, or hesitation, especially under load or during acceleration.

  • White Exhaust Smoke
    If coolant enters the combustion chamber due to a compromised EGR cooler, it can produce white smoke from the tailpipe—another sign of overheating risks.

A clogged EGR cooler should not be ignored. It not only leads to inefficient engine operation but also increases the risk of engine overheating and potential long-term damage. Regular maintenance, such as coolant flushes and EGR system cleanings, can help prevent buildup and maintain optimal engine temperature. If you suspect EGR-related issues, it's best to have the system inspected by a qualified diesel technician.

 

When regularly maintained and operating under clean conditions, it typically lasts several years or thousands of engine operating hours.

You might notice increased engine temperature, reduced performance, or visible coolant leaks around the cooler housing.

By checking for pressure differentials, inspecting for coolant leakage, and measuring exhaust gas temperature before and after the cooler.

Ensure clean coolant, eradicate blockages by flushing regularly, and inspect for signs of cracks or corrosion.
