What Engines Are Compatible With 2006 Jeep Liberty

Hello, The easy answer is that you will be best off replacing the engine with the same type that is currently installed. Compatibility, fitment, software, and hardware issues will exist when attempting to replace the engine with other than the original type. You would end up replacing the engine, wiring harness, control module, and any other component in the vehicle that does not agree with the new setup would need replacement or reprogrammed.
