* Specificity is Key: There were multiple engine options available for the 1991 Corolla. To get the right diagram, I'd need to know the specific engine code (e.g., 4A-FE, 4A-GE, etc.). You can find this information on your vehicle's VIN plate or service manual.
* Copyright and Legality: Providing detailed technical diagrams can be a copyright issue.
Where to Find a Diagram:
1. Your Owner's Manual: The owner's manual for your specific Corolla model will likely have some basic engine diagrams.
2. Factory Service Manual: The best resource is a Toyota factory service manual for your year and model. You can often find digital copies online or at your local auto parts store.
3. Online Resources: Websites like AutoZone, PartsGeek, and RepairPal often have diagrams for popular car models. However, ensure they match your engine code.
General Tips for Finding the Right Diagram:
* Look for the Engine Code: This is essential. The code is usually located on a sticker near the engine.
* Use Specific Search Terms: When searching online, be specific with your model year, engine code, and "engine diagram."
* Check Reputable Sources: Stick to trusted websites and sources for technical diagrams.
