To be certain, you should:
1. Consult your owner's manual: This is the best source of information.
2. Look closely at the bottom of the radiator: It's usually a small, threaded plug, often made of brass or plastic.
3. Search online for "1984 Camaro radiator drain plug location" along with your engine type (e.g., "1984 Camaro 2.8L radiator drain plug"). Pictures from other owners might help.
Important Note: When draining the radiator, always place a suitable container underneath to catch the coolant and allow it to cool completely before working on it. Coolant is toxic, so wear appropriate safety gear.
