* Your Owner's Manual: Check your owner's manual. While it might not be a detailed schematic, it often includes a simplified diagram of the major components.
* Online Repair Manuals: Websites like Haynes.com or ChiltonDIY.com offer repair manuals (often for a fee) that include detailed diagrams and explanations of the cooling system. These are generally much more comprehensive than what you'd find in an owner's manual.
* Ford's Website (Possibly): Ford's official website might have some diagrams available, but this is less likely than finding them through a repair manual service.
* Online Forums: Searching on forums dedicated to Ford Tempos or classic Ford cars might turn up a user-submitted diagram. However, the quality and accuracy of these diagrams can vary.
Important Note: When working on your cooling system, always ensure the system is completely cool before starting any work to avoid serious burns. Also, be aware of the potential for pressure within the system even after the engine has cooled.
