The Ford Ranger is a popular mid-size pickup truck known for its versatility and off-road capabilities. It has been in production since 1983 and has undergone several changes over the years. One of the most significant changes was the introduction of the 4.0-liter V6 engine in 1997. This engine was available in two different configurations: OHV (overhead valve) and SOHC (single overhead cam). Both engines have their own advantages and disadvantages, and the choice between them depends on your individual needs and preferences.
