The 2001 Cadillac SLS is equipped with a 4.6L Northstar V8 engine. If you're looking for an engine interchange, you can consider using another 4.6L Northstar engine from similar models, such as the Cadillac STS or other Northstar-equipped Cadillacs from the same era. However, it’s important to ensure compatibility with the engine's electronic systems and accessories. Always verify the specific engine code and related components before proceeding with an interchange.
