Salvage yards, which take workable parts out of cars that are beyond repair, usually offer a warranty on any parts that they salvage, such as engines. Although many salvage yards repair engines to the best of their ability, the engines can still break.
Typically, there is a warranty attached to any purchase at a salvage yard that provides a full money-back guarantee up to the purchase price. The length of the warranty is usually 90 days at maximum; however, it often covers only the engine itself. The buyer must pay out of pocket for the cost of labor for removing, servicing or reinstalling the engine.
