3 Year, 100,000 mile warranty

I. The remanufacturer warrants to the installation facility that it will replace, repair or refund, at remanufacturers' sole option, any long block engine for gasoline, on road applications, supplied by the remanufacturer, which is defective in material or workmanship, for three years (36 months) or 100,000 miles, whichever occurs first. This warranty is limited to the original installer. This warranty covers vehicle engines installed in passenger vehicles (includes vans, cars and pickup trucks up to 1 ton). This warranty is limited to defects in workmanship and materials furnished by the remanufacturer and is not an unconditional guarantee against all hazards or failures (see exclusions and limitations to Limited Warranty). All repairs must have prior factory authorization.

If it is determined that an engine or engine part furnished by the remanufacturer is defective in workmanship or material, the factory will allow a labor adjustment according to the most recent Alldata OEM Warranty Rate up to $50.00/hour. Do-it-yourself or repairs made by an un-licensed repair facility will be paid at a rate not to exceed $25 per flat rate hour, with a maximum labor payout of $300 per engine purchased. Labor allowances shall be paid only upon a determination that an engine or part supplied by the remanufacturer is defective in material or workmanship. The limited warranty period commences on the date of installation of the engine, which is the date on which the remanufactured engine is first installed in the vehicle.

A warranty card, enclosed with the engine must be filled out with installation date and vehicle mileage to validate warranty. The warranty registration card MUST be returned within thirty days of installation or the warranty will be voided.

This limited warranty is the sole and exclusive express or implied warranty made by the remanufacturer with respect to the remanufacturer's engines and parts, and is given in lieu of any other warranty. To the extent allowed by law, any and all express or implied warranties not set forth herein are waived and disclaimed, including any implied warranty of merchantability or fitness for a particular use. Liabilities under this warranty are limited solely and exclusively to repair or replacement of engines or parts according to the terms of this warranty only. Some states do not allow limitations on implied warranties or the exclusion or limitation of consequential or incidental damages; therefore, some of the exclusions and limitations may not apply to you. This limited warranty gives you specific legal rights and you may also have other rights that vary from state to state.

In the event that any provision of this warranty should be or become invalid or unenforceable because of any laws, the remaining terms and conditions hereof shall remain in full force and effect.
