J&K Engines offers a warranty for their remanufactured engines. The warranty is for 12 months and unlimited miles for non-commercial applications, and for commercial applications, it is limited to 50,000 miles. In the event of a failure, J&K Engines will repair or replace the long block assembly at their option. The warranty covers defects in workmanship and materials when the engine is installed and maintained according to OEM specifications. However, the warranty does not cover improper installation, overheating, fuel contamination, racing or competition use, damage from accidents or misuse, use of unauthorized parts or modifications, among other conditions. Customers must complete the warranty registration and retain all documentation related to the installation of the engine. If a warranty claim arises, customers should contact J&K Engines to initiate the process. Core return is also required for credit. For more detailed information about the warranty terms and conditions, customers can visit J&K Engines' Warranty page.
