To find it:
* Look closely near the grille: Many S10s have this secondary latch located somewhere near the top center of the grille, sometimes behind a small panel. You might need a flashlight.
* Feel around: Run your hand along the top of the radiator support area (carefully, it's metal!). The latch might be a small handle or lever.
* Consult your owner's manual: If you have it, the owner's manual should show a diagram of the hood latch mechanism.
* Search online: A quick image search for "2001 Chevy S10 Extreme hood latch" might show you exactly where it is.
Safety First: Before you start blindly searching, make sure you have good lighting and are working in a safe, stable area. Don't force anything. If you can't find the latch easily, it's better to seek help from a mechanic than risk damaging your vehicle.
