Flint Engine Operations (previously,Flint Engine South) is aGeneral Motorsautomobileengine factory inFlint, Michigan. The plant opened in 2002 and is named to replace theFlint North engine plant. The plant currently produces the small four-cylinderSGE andDuramax I6 engines. The factory receives cast engine blocks from Defiance Foundry inDefiance, Ohio andSaginaw Metal Casting Operations inSaginaw, Michigan. It replacedFlint North.
Flint Engine South began operations in 2002.[2] It produced inline five and six cylinder versions of theGM Atlas engine[3][4] until that engine line was discontinued in 2009 alongside theGMT360 platform.[5] Shortly after Flint Engine South was completed, Powertrain Flint (aka Flint North) was closed and demolished.[6]
Flint Engine South also produced3.6L High Feature DOHC V6 engines (HFV6) for theChevrolet Traverse,Buick Enclave, andGMC Acadiacrossover utility vehicles andCadillac CTS andSTS sedans.[7] High Feature engines were produced in the northern half of the plant.[8]
On September 25, 2008, GM announced a $370 million investment to build another engine plant at the Flint South complex. The new plant was designed to produce the 1.4LGM Family 0 engine ("FamZero") for theChevrolet Cruze andVolt models beginning in 2010.[9] However, major work was suspended that December as theautomotive industry crisis worsened,[10] eventually resulting in theGeneral Motors Chapter 11 reorganization of 2009. By February 2009, GM announced that rather than a new plant, the existing plant would be retooled for FamZero.[4] That October, GM announced it was investing $200 million to complete the retooling, with production scheduled to start in late 2010.[11] In November 2010, GM announced additional investments in Flint to increase production to a planned 1,200 FamZero engines per day by the end of 2012.[7]

The plant was renamed to Flint Engine Operations in approximately 2011.[12] GM announced a $215 million investment in 2013 for the Flint plant, which included plans to retool and upgrade the plant to accommodate production of the newGM small gasoline engine (SGE) and updated HFV6 engines;[13] the SGE was scheduled to replace the FamZero.[14] When the second-generationChevrolet Colorado was unveiled for North America that November, GM announced the optional 3.6L HFV6 engine would be built at Flint.[15] By 2015, Flint Engine Operations had built one million FamZero engines, shortly before shifting production to the1.5L SGE I4 "Ecotec".[16]
In January 2018, GM announced it would assemble theDuramax I6 engine at Flint Engine Operations.[2] Five years later, in January 2023, GM announced it would invest $579 million to add an assembly line at Flint for thesixth-generation small-block V8 gasoline engines.[17]
