Ford 4.2L Essex V-6

4.2L V-6 Engine Specs

The Ford 4.2L Essex V-6 replaced the 300 cid I-6 beginning with the 1997 model year Ford F-150. During its final production year, the engine was rated at 202 horsepower and 260 lb-ft of torque. It's retirement following the 2008 model year is representative of the high performance potential of modern, forced induction V-6 engines. The EcoBoost, which was introduced several years after production of the 4.2L ceased, produces significantly greater horsepower and torque at a much smaller engine displacement. Simply put, the 4.2L Essex became dated, but not before a lengthy production run. At one point, the engine was rated amongst the most reliable choices for Ford F-150 buyers. Common problems with the 4.2L V-6 included a faulty factory installed front cover gasket, which only affected 1997 and 1998 model year engines. On all models, cracking of the lower intake manifold is somewhat common. After withdrawing the 4.2L from the F-150's engine options, only V-8 engines were available for the 2009 and 2010 model years.
