* Engine Variation: Toyota pickups from 1986 came with various engine options (22R, 22RE, 3.0L V6, etc.). Each engine has different spark plug specifications.
* Recommended Gap: The correct gap is critical for proper engine performance. It's not safe to rely on general information.
* Owner's Manual: The best source for this information is your 1986 Toyota Pickup owner's manual. It will have the specific spark plug gap for your engine.
Here's how to find the right information:
1. Locate your owner's manual: If you don't have it, try searching online (some manuals are available as PDFs) or contacting a Toyota dealership.
2. Find the section on engine maintenance: This will likely include information on spark plugs, including the recommended gap.
3. Check the engine type: Make sure the information you're reading is for your specific engine.
4. Use a gap tool: If you need to adjust the spark plug gap, use a spark plug gap tool to set it accurately.
If you can't find the information in your owner's manual, contact a Toyota dealership or a reputable mechanic for assistance.
