Will Ford Taurus 3.5l engine for into Ford Explorer

Ed's post mentioned most of the problems you may encounter. But, you want to put an older engine in a newer vehicle. You should take the electronics (computer) from the older vehicle. There is a possibility your newer engine will have a sensor or two not on the older engine or located in a different location. It is a good idea to also mark on the older engine it's VIN number and what year vehicle you took it out off. If operating specifications are slightly different from the older engine's year than the newer engine, a mechanic might be pulling his hair out trying to adjust an older engine to newer specifications. Same idea goes for engine parts.
