Chrysler 2.2 & 2.5 engine

The 2.2 and 2.5 are a family of inline-4 engines developed by Chrysler Corporation originally for the Chrysler K- and L-platforms cars and subsequently used in many other Chrysler vehicles. After its launch in 1981, it became the basis for all Chrysler-developed 4-cylinder engines until the Chrysler 1.8, 2.0 & 2.4 engine family was released in 1994. It was the first Chrysler engineered four cylinder engine since the Chrysler flathead four cylinder was discontinued in 1933.
