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.
"This Product Doesn't Have a Core"
Designed to provide a reliable pathway for coolant flow to and from the EGR valve assembly, the OEM 2127034PE Coolant Pipe fits Paccar MX13 engines manufactured from 2017 to 2021. This pipe helps maintain controlled temperatures within the EGR system by directing coolant through critical areas, supporting stable operation during demanding conditions. Its OEM-grade construction ensures accurate fitment, secure sealing, and durability against heat, vibration, and coolant exposure. When signs such as leaks, cracking, or restricted flow develop, this component offers a dependable replacement option. Built with quality materials and precise engineering, it supports consistent EGR temperature regulation across all compatible MX13 applications within this model range.

This coolant pipe is a dedicated coolant-water conduit that connects between the engine coolant system and the EGR system (Exhaust Gas Recirculation) — specifically linking to the EGR valve or EGR cooler assembly. Its purpose is to route coolant to cool the recirculated exhaust gases (or related EGR components), helping manage exhaust gas temperature and protect engine integrity.
Because EGR systems often run very hot (recirculating exhaust gases), having a reliable coolant supply routed via this pipe is critical to prevent overheating and maintain emissions-system durability.
Typical Components of the Coolant Pipe Assembly
When you inspect or replace an EGR coolant pipe assembly like OEM 2127034PE, it generally comprises several functional parts:
- Steel or aluminum coolant pipe / tube
- the main rigid conduit or pipe segment carrying coolant from the engine’s cooling system to the EGR valve or cooler.
- Flanges or mounting ends
- machined ends or flanges where the pipe bolts or clamps to the EGR valve / cooler or to the engine’s coolant passages. These ensure a secure, leak-free connection.
- Sealing elements (gaskets / o-rings / sealing rings / grommets)
- at each connection point to prevent coolant leaks under pressure or temperature fluctuations. Proper sealing is essential during installation.
- Coolant flow passage(s)
- the internal bore within the pipe through which engine coolant flows; this pathway must be free from obstructions and built to handle coolant pressure and temperature.
- Mounting brackets or supports (if applicable)
- on some designs, the pipe may include or rely on brackets/clamps to secure it to the engine or chassis to avoid vibration, movement, or stress on the joints.
- Connection hardware (bolts, clamps, clamps with banjo-style fittings — depending on design)
- used to attach the coolant pipe securely to other components (EGR valve, cooler, coolant ports) and to hold sealing components in place.
- Coolant-resistant coating or material choice
- the pipe and fittings are made from metal or alloy compatible with coolant and high temperatures; the material must resist corrosion, thermal cycling, and coolant chemistry to ensure long service life.
Every piece — from the pipe itself to the seals and connections — plays a part in making sure coolant gets reliably to and from the EGR system. If any component fails (e.g. leaky gasket, cracked pipe, poor mounting), this can lead to coolant loss, overheating of the EGR valve or cooler, reduced emissions-system performance, or even engine damage.
Using the correct OEM pipe (with the right diameter, flange pattern, sealing surfaces, and coolant passage design) is critical. The OEM 2127034PE is engineered to match exactly the coolant port layout and physical configuration of MX13 engines 2017–2021, ensuring proper fitment and reliable coolant flow.
The EGR valve coolant pipe helps control exhaust gas temperatures by circulating coolant through the EGR system. When this pipe begins to fail, it can lead to leaks, overheating, and potential damage to nearby components. Knowing when to replace it can prevent costly repairs later.
Most EGR coolant pipes fail due to corrosion, heat stress, vibration, or coolant contamination. Because the pipe carries hot coolant, even a small crack can quickly become a major issue.
You should consider replacing the EGR valve coolant pipe if you notice:
- Coolant leaks
- near the EGR valve or intake area
- Low coolant levels
- with no obvious external leak
- Burning smells
- caused by coolant dripping on hot engine parts
- White residue or crust
- on or around the pipe
- Overheating
- during normal driving
- Check Engine Light
- related to EGR flow or temperature issues
If the pipe shows visible damage, corrosion, or repeated leaking, replacement is the safest solution. Delaying repair can allow coolant loss to worsen, leading to overheating and further engine stress.
Regular inspections during routine service help catch early signs of wear. Replacing the EGR valve coolant pipe promptly keeps your cooling and emissions systems operating reliably.
Coolant loss, overheating warnings, or moisture around the EGR valve area may occur.
By providing continuous coolant flow, it helps the EGR valve operate within its intended temperature range.
It should be checked during coolant leak diagnostics or when servicing the EGR valve assembly.
Yes, prolonged vibration can fatigue the pipe or loosen its mounting points over time.
