To find it, you'll need to:
1. Locate the radiator: It's the large metal unit at the front of the engine compartment.
2. Look at the bottom of the radiator: The drain plug is usually located at the bottom of the radiator, on either the driver's side or passenger's side. It's typically a small, threaded plug, often made of plastic or metal. It may be recessed slightly.
3. Inspect carefully: It might be hidden behind a shroud or plastic cover; carefully examine the lower portion of the radiator. A flashlight can be helpful.
4. Consult a repair manual: A repair manual specific to your 1997 Chevy Blazer (including the engine size) will show the exact location of the drain plug. You can find these online or at auto parts stores.
Important Note: When draining the radiator, always be prepared to catch the coolant in a suitable container. Coolant is toxic and needs to be disposed of properly according to your local regulations. Allow the engine to cool completely before attempting to drain the radiator to avoid burns.
