GM Powertrain Flint North (GMPT Flint North) was a General Motors automobile engine and components plant located at the Stewart Avenue exit of I-475 in Flint, Michigan. The plant consisted of several factories that combine to make the Flint North Powertrain plant.
The 4,000,000-square-foot (370,000 m2) plant opened in 1905 as part of the large Buick Motor Company facilities in Flint. The Factory 36 building was completed in 1951 and had 1,130,000 sq ft (105,000 m2) of floor area, producing both V8 and V6 engines. [1] The factory received cast engine blocks from Defiance Foundry in Defiance, Ohio and Saginaw Metal Casting Operations in Saginaw, Michigan. The employees of Powertrain Flint North were represented by UAW Local 599.
Engine component manufacturing was shifted from Factory 31 to Factory 36 in 2004. [2] The engine plant (Factory 36) portion of Powertrain Flint North closed in 2008. It is famous for building the GM 3800 engine, one of the longest-produced automobile engines in history; the final 3800 was produced on August 22, 2008. [3] Shortly after its closure, scavengers stole an estimated US$100,000 of metal and wire from the building. [1] The last employees left the site on October 30, 2010. [4]
The remaining factories (5, 9, 10, 14, 25, 29, 75 and 81) which composed the maintenance, sanitation and components producing buildings of the plant, closed permanently on December 6, 2010. [5] [6]
With its closure in 2010, Powertrain Flint North was the last operating plant at the century-old Buick City factory complex. It was replaced by Flint Engine South, which had begun production in 2002.
Buick is a division of the American automobile manufacturer General Motors (GM). Started by automotive pioneer David Dunbar Buick in 1899, it was among the first American automobile brands and was the company that established General Motors in 1908.

With the demise of Oldsmobile in 2004, Buick became the oldest surviving American carmaker.

The Buick Regal is a line of mid-size cars marketed by Buick since 1973. For nearly its entire production, the Regal has served as the premium mid-size/intermediate offering of the Buick product range.

From the 1970s to the 1990s, the Regal served as the Buick counterpart of the Pontiac Grand Prix and Oldsmobile Cutlass Supreme.
The Buick LaCrosse is a four-door, front-wheel-drive sedan manufactured by Buick since model year 2005, and marketed variously across four generations for the North American and Chinese markets.
The Buick V6 is an OHV V6 engine developed by the Buick division of General Motors and first introduced in 1962. The engine was originally 198 cu in (3.2 L) and was marketed as the Fireball engine. GM continued to develop and refine the 3.8 L (230 cu in) V6, eventually and commonly referred to simply as the 3800, through numerous iterations.
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines. These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line. These engines are the first cam-in-block engines to implement variable valve timing, and won the 2006 Breakthrough Award from Popular Mechanics for this innovation. For the 2007 model year, the 3900 engine featured optional displacement on demand or "Active Fuel Management" which deactivates a bank of cylinders under light load to increase highway fuel economy. It was rumored that GM would produce a 3-valve design, but that never came to be. These engines were produced primarily at the GM factory in Tonawanda, New York, and at the Ramos Arizpe engine plant in Mexico. The assembly line for this engine was manufactured by Hirata Corporation at its powertrain facility in Kumamoto, Japan.
