Where is the coolant drain plug on a 2001 Chevy s10?

The coolant drain plug location on a 2001 Chevy S10 depends slightly on the engine type (a 2.2L 4-cylinder or a 4.3L V6). There isn't a single universally located drain plug like some vehicles.

To find it, you'll need to:

1. Locate the engine block: This is the large, cast-iron piece that holds the engine's cylinders. The coolant drain plug is usually located on the *bottom* of the engine block.

2. Look closely at the bottom of the engine block: The plug is typically a bolt or a smaller plug. It might be a slightly different shape or size than other bolts in the area. It will be located near the radiator hose connections, but not directly on them.

3. Consult a repair manual: A repair manual specific to your 2001 Chevy S10 (including the engine size) will show you exactly where the drain plug is located. This is the most reliable method. You can find these online or at auto parts stores.

Important Note: Before attempting to drain the coolant, make sure the engine is completely cool to prevent burns. Have a suitable drain pan ready to catch the coolant. Also be aware that coolant is toxic, so handle it appropriately.
