Understanding Our 1-Year Unlimited Mileage Warranty

When you invest in a remanufactured diesel engine from US Engine Production, you are not just purchasing a piece of machinery; you are investing in reliability, performance, and peace of mind. We understand that commercial vehicles and industrial equipment are the lifeblood of your business. Downtime means lost revenue, and unexpected repair costs can severely impact your bottom line. That is why we proudly stand behind our products with an industry-leading 1-year unlimited mileage warranty. This comprehensive warranty is designed to provide you with the utmost confidence in the quality and durability of our remanufactured engines, ensuring that you can keep your operations running smoothly without the constant worry of catastrophic engine failure.

Unlike many other engine rebuilders or suppliers who impose strict mileage caps on their warranties, US Engine Production believes that you should be able to use your equipment as much as your business demands. Whether you are an owner-operator hauling freight cross-country, a construction company running heavy machinery around the clock, or a fleet manager overseeing dozens of delivery vehicles, our no-mileage-cap policy means that your engine is protected for a full 365 days from the date of purchase, regardless of how many miles you drive or hours you operate. This commitment to quality reflects our rigorous remanufacturing process, where every engine is meticulously disassembled, inspected, machined, and reassembled using top-tier components to meet or exceed original equipment manufacturer specifications.

Our 1-year unlimited mileage warranty applies to a wide range of the engines we offer, including popular models from leading manufacturers. Whether you are relying on the robust power of Cummins engines, the legendary durability of Caterpillar engines, or the proven efficiency of Detroit Diesel engines, you can rest assured that your investment is protected. We have built our reputation over decades of serving the diesel community from our headquarters in Lindenhurst, NY, and this warranty is a testament to our unwavering dedication to customer satisfaction and product excellence. If you have any questions about how this warranty applies to your specific engine needs, we encourage you to review our frequently asked questions or reach out to our knowledgeable team.

Comprehensive Coverage for Internal Engine Components

The core of our 1-year unlimited mileage warranty is its extensive coverage of the engine's internal components. When we remanufacture an engine, we do not simply replace the parts that are visibly broken; we conduct a complete overhaul to ensure that every critical component functions flawlessly. Therefore, our warranty covers all internally lubricated parts contained within the engine block and cylinder head. This includes, but is not limited to, the pistons, piston rings, connecting rods, main and rod bearings, crankshaft, camshaft, timing gears, oil pump, valves, valve springs, pushrods, and rocker arms. If any of these covered internal components fail due to a defect in materials or workmanship during the warranty period, US Engine Production will repair or replace the defective part or the entire engine at our discretion.

We recognize that the integrity of the engine block and cylinder head castings is paramount to the engine's overall performance and longevity. As such, our warranty also covers the engine block and cylinder heads against cracks or structural failures that are not the result of overheating, freezing, or physical damage caused by external factors. Our state-of-the-art machining processes, including magnafluxing and pressure testing, are designed to identify and eliminate any compromised castings before they ever make it into a finished product. This meticulous attention to detail allows us to offer such robust coverage with confidence.

It is important to note that our warranty is a parts and labor warranty, subject to specific terms and conditions. In the event of a covered failure, we will provide the necessary replacement parts and cover the approved labor costs associated with the repair, based on standard industry labor guides. We work closely with a network of authorized repair facilities across the country to ensure that any necessary warranty work is performed promptly and professionally, minimizing your downtime.

What Is Not Covered Under the Warranty

While our 1-year unlimited mileage warranty is incredibly comprehensive, it is essential to understand its limitations to avoid any misunderstandings. The warranty is specifically designed to cover defects in materials and workmanship related to the remanufactured long block or complete engine assembly provided by US Engine Production. It does not cover external accessories, bolt-on components, or parts that are transferred from your original engine to the remanufactured unit, unless those specific parts were supplied and installed by us as part of the purchase agreement.

Items typically excluded from coverage include, but are not limited to, fuel injectors, fuel injection pumps, turbochargers, water pumps, alternators, starters, air compressors, power steering pumps, exhaust manifolds, sensors, wiring harnesses, and electronic control modules. Failures caused by the malfunction of these external components are not covered. For example, if a faulty fuel injector causes a piston to melt, or if a failed water pump leads to severe engine overheating and a cracked cylinder head, the resulting engine damage would not be covered under our warranty, as the root cause was a non-covered external part.

Furthermore, the warranty does not cover damage resulting from improper installation, negligence, abuse, misuse, or lack of proper maintenance. This includes running the engine without adequate coolant or lubricating oil, using incorrect or contaminated fluids, over-revving, or altering the engine's performance parameters beyond original specifications. Damage caused by environmental factors, accidents, fire, theft, or acts of nature is also excluded. We strongly advise all our customers to have their remanufactured engines installed by certified and experienced diesel technicians to ensure that all installation procedures, including priming the oil system and verifying proper fuel pressure, are followed correctly.

The Importance of Proper Installation and Maintenance

To maintain the validity of your 1-year unlimited mileage warranty, strict adherence to proper installation procedures and ongoing maintenance schedules is required. The installation of a remanufactured diesel engine is a complex process that demands specialized knowledge and tools. We require that the installation be performed by a licensed automotive or diesel repair facility. The installing technician must thoroughly clean and inspect all transferred components, flush the cooling system, replace the oil cooler, and install new oil and fuel filters.

Failure to properly clean the intake manifold, charge air cooler, and exhaust system can lead to catastrophic engine failure if debris from the previous engine failure is ingested into the new engine. Such failures are easily identifiable during a warranty inspection and will void the coverage. Additionally, the engine must be filled with the correct grade and quantity of oil and coolant as specified by the original manufacturer. We require documentation of the installation, including the repair order from the installing facility, to be kept on file in the event a warranty claim needs to be initiated.

Once the engine is installed and running, regular maintenance is crucial not only for keeping your warranty intact but also for maximizing the lifespan of your investment. You must adhere to the recommended service intervals for oil changes, filter replacements, and cooling system maintenance. Keep all receipts and records of these maintenance services, as they will be required to process any warranty claims. Neglecting routine maintenance is one of the leading causes of premature engine failure and will unfortunately void your warranty coverage. By partnering with a reputable service center and staying proactive with your vehicle's upkeep, you can enjoy years of reliable service from your US Engine Production remanufactured engine.

How to File a Warranty Claim with US Engine Production

In the unlikely event that you experience an issue with your remanufactured engine during the warranty period, our goal is to resolve the situation as quickly and efficiently as possible. The first step in filing a warranty claim is to stop operating the vehicle or equipment immediately to prevent any further damage. Continuing to run an engine that is exhibiting signs of failure, such as knocking, overheating, or significant loss of oil pressure, can exacerbate the problem and potentially void your warranty coverage.

Next, you must contact the US Engine Production warranty department before any diagnostic work or repairs are initiated. You can reach our dedicated support team by calling (631) 991-7700. Our representatives will guide you through the initial troubleshooting process and provide you with a warranty claim form. We will require specific information, including your original invoice number, the engine serial number, the current mileage or hours on the engine, and a detailed description of the problem you are experiencing. We may also request copies of your installation repair order and maintenance records at this stage.

Once the initial claim is filed, we will direct you to an authorized repair facility or work with your preferred certified shop to diagnose the issue. The shop must contact us with their diagnostic findings and a written estimate for the necessary repairs before any work begins. US Engine Production reserves the right to inspect the engine or the failed components, either through photographic evidence, independent third-party inspection, or by requiring the parts to be returned to our facility in Lindenhurst, NY, for evaluation. If the failure is determined to be covered under our 1-year unlimited mileage warranty, we will authorize the repairs and cover the costs of parts and approved labor. We are committed to transparency and fairness throughout the claims process, ensuring that you receive the support you need to get back to work.
