The UEAT liability is solely and exclusively limited to supplying low mileage used engines replacement whenever one is available or refunding customer with purchase price. UEAT doesn’t accept any liability associated with labour costs, replacement of engine oil, transmission fluid and antifreeze, or damage to other engine or transmission parts or components towing charges, telephone calls, freight, lost profits, lost time, substitute transportation or replacement vehicle or any other consequential damages. UEAT also not responsible for any failure resulting from improper installation, modification of the product faulty or incompatible parts and accessories and/or abnormal use of operation. State and federal laws regulate odometer mileage for most used automobiles, but odometer mileage determinations for used engines, transmissions and their parts are not practically possible.

Determination of mileage use for used engines cannot be done with certainty since the engines are often sold and/or transferred apart from the original vehicle in which they were originally installed. Therefore, all representations of mileage are estimates.

UEAT offers an extensive engine and transmission warranty regardless of the mileage, based upon our expertise and evaluation of our products.




We need to follow few steps before installation and an operation of recycled or used engine and transmission. It is always required to perform certain inspections to change over accessories and make a routine maintenance to insure uninterrupted service. Some used engine parts and components have been left attached for your convenience only. These accessories may save your time during installation; however, the professional installer is accountable for the parts and accessories exchange. All parts, change over accessories, wear and tear items are left on the engine block for your suitability and are not covered under warranty.
