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 International Navistar DT466 EGR Cooler Pipe for 2006-2008 (OEM 1858647C1) plays a crucial role in ensuring the engine’s emission system functions smoothly. The EGR (Exhaust Gas Recirculation) system is designed to reduce harmful nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine. The EGR cooler pipe is an essential component of this system, channeling the gases between the cooler and the engine.
When you purchase the EGR cooler pipe kit, you can expect the following key components:
- EGR cooler pipe
- Connects the cooler to the engine.
- Clamps and fasteners
- Secure the pipe in place, ensuring a tight seal.
- Gaskets
- Provide a reliable seal between the pipe and adjoining parts to prevent leaks.
- Mounting hardware
- Ensures the pipe and cooler are properly aligned and secure.
Over time, the EGR cooler pipe may wear out due to high heat and pressure. Replacing it with a quality OEM kit like the 1858647C1 is essential to keep the emissions system functioning properly, reduce exhaust leaks, and ensure regulatory compliance.
An EGR cooler pipe plays a key role in directing exhaust gases through the cooling system, and when it starts to fail, it can lead to noticeable issues within the engine and emissions system. Because it handles both heat and exhaust flow, wear or damage can quickly affect overall operation.
Recognizing the early symptoms can help prevent further damage and more costly repairs.
Here are common signs of a failing EGR cooler pipe:
- Coolant leaks around the pipe area
- Cracks or weakened connections can allow coolant to escape, often visible near the pipe or surrounding components.
- White exhaust smoke
- If coolant enters the exhaust stream due to a leak, it can produce white smoke from the tailpipe.
- Drop in coolant levels
- Unexplained coolant loss may indicate a leak within the EGR cooler pipe or connected components.
- Overheating issues
- A compromised pipe can affect the cooling process, leading to higher engine temperatures.
- Visible cracks or corrosion
- Exposure to heat and moisture can cause the pipe to deteriorate over time, making it more prone to failure.
- Exhaust leaks or unusual smells
- A damaged pipe may allow exhaust gases to escape before reaching the proper channels, sometimes creating noticeable odors.
Catching these symptoms early can help you address the issue before it impacts other parts of the engine or emissions system.
It can be damaged by excessive heat, corrosion, vibration, or restricted exhaust flow in the EGR system.
Inspect it regularly for leaks, soot residue, or cracks, and clean any buildup to maintain proper flow.
Soot accumulation can restrict gas flow, cause back pressure, and reduce EGR cooling efficiency.
Remove the pipe and use a non-abrasive solvent or brush to clean the interior, ensuring no debris remains.
