Where is the radiator drain plug on a 1986 corvette?

The radiator drain plug on a 1986 Corvette is located at the bottom of the radiator, on the driver's side. It's usually a small, easily accessible plug. You'll likely need a wrench (likely a small one, possibly even a pair of pliers depending on the type of plug). However, the exact size and accessibility might vary slightly depending on any aftermarket modifications to the cooling system.
