First manufactured in 1990, the Ford Explorer is a popular sport utility vehicle that has seen multiple generations. The Ford Explorer V6 engine used in each generation has varied, though. The first generation used a 4.0-liter Cologne V6 engine. The Cologne is a pushrod OHV engine, which features the pushrods over the cylinder head rather than the camshaft. These engines are simpler in design and take up less space under the hood compared to other engine types. By the second generation, three engines were available: the pushrod Cologne, a SOHC Cologne, and the 5.0-liter Windsor OHV. The Windsor is a small block engine with a total displacement of about 302 cubic inches, which also took up little room in the engine compartment. Later engines offered in the Explorer are a modular engine, the Ecoboost Inline 6, Duratec V6, and a Cyclone V6. The variety of engine styles used in different generations of Ford Explorer mean that it is essential to know your model year when shopping through the large inventory on eBay. With the right Ford Explorer V6 engine, your SUV can last through several more generations.Shop the large inventory of motors, parts, accessories, and complete Ford car and truck engines!
