Thermostat location on a 1993 Corvette?

The thermostat on a 1993 Corvette is located on the engine, at the back of the engine block, near the water pump. It's not easily accessible; you'll likely need to remove some components to reach it. A repair manual specific to your 1993 Corvette (either the LT1 or the base engine) will provide the most accurate location and removal instructions.
