1. Repair Manuals: The most comprehensive source is a repair manual specific to your 1999 Mercury Sable. These manuals (like those from Haynes or Chilton) will have detailed diagrams, schematics, and component locations for the power steering system. You can find these manuals at auto parts stores, online retailers (Amazon, eBay), or through library systems.
2. Online Automotive Databases (Subscription-Based): Websites like AllDataDIY or Mitchell 1 provide detailed repair information, including diagrams, for a fee. These are generally used by professional mechanics but offer the most in-depth data.
3. Ford Parts Websites: While they might not have diagrams, Ford's official parts websites (or those of their authorized dealers) can provide parts diagrams showing the components of the power steering system. This can help you identify parts if you're troubleshooting a problem, but it won't show the fluid lines or connections in the detail you'd find in a repair manual.
4. Local Mechanic: A trusted local mechanic is another good resource. They likely have access to repair manuals or online databases and can help you understand the system, even drawing a quick sketch if needed.
Important Note: When working on your power steering system, be aware that it contains pressurized fluid under high pressure. Improper handling can lead to injury or fluid spills. If you are not comfortable working on your car's power steering system, it's best to have it serviced by a qualified mechanic.
