You generally don't have to completely remove the intake manifold to access the knock sensor on a 2001 Chevy 6.0L. The location varies slightly depending on the exact engine configuration and accessories, but access is usually possible with partial removal or strategic maneuvering. You'll likely need to remove some components attached to the intake manifold (like the air intake system, throttle body, etc.) to get a clear path. Some mechanics may even be able to reach it with only selective component removal and careful use of tools.
Consult a repair manual specific to your year and model (2001 Chevy HD 6.0L) for the precise location and access procedure. These manuals provide detailed diagrams and instructions, helping you avoid unnecessary work. Improper removal of intake components can lead to difficulties during reassembly.
