How do you put coolant in a 1994 Lexus sc400?

To add coolant to a 1994 Lexus SC400, first ensure the engine is cool. Open the hood and locate the coolant reservoir, which is typically near the radiator. Remove the cap and pour the appropriate coolant mixture (50% coolant and 50% distilled water) into the reservoir until it reaches the designated fill line. Replace the cap securely before starting the engine to allow the system to circulate the coolant.
