The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
But the main problem that soon damaged its reputation was poor quality control at the new, purpose-built Linwood plant, and an underdeveloped design that was rushed into production within three years of planning. Quality issues included the frequent failure of gearboxes and water pumps, poor engine cooling that often resulted in motors ...

Cars seven years old have had their coolant go out-of-date and then have another two years for acid coolant to find its way into the head bolt wells and do the damage; the nine-year spike may be due to lease returns that are reconditioned at two years.
According to auto authority Edmunds, a new car loses around 11% of its value the moment you leave the lot and 15% to 25% each of its first five years of ownership.
For the 1963 model year, Cadillac redesigned its V8 engine, modernizing the tooling used in the production line while optimizing the engine's design.
