The service manual is the most reliable source for information regarding the correct fluid for a clutch master cylinder. It provides detailed specifications and guidelines that are designed specifically for the vehicle in question. The service manual typically includes fluid types, capacities, and manufacturer recommendations that are crucial for ensuring optimal performance and longevity of the vehicle’s clutch system.

While OSHA guidelines focus on safety and health regulations in the workplace, the parts department may offer parts but not necessarily the specific fluid details. The SDS (Safety Data Sheet) book provides safety information about the substances used in automotive fluids but does not specify the correct fluid types for a particular vehicle's components. Therefore, the service manual is the appropriate resource to ensure that the correct fluid is used for the clutch master cylinder.
