Where do you put the coolant in a Toyota 2000 echo?

To add coolant to a 2000 Toyota Echo, open the hood and locate the coolant reservoir, which is typically a translucent plastic tank near the radiator. Ensure the engine is cool, then remove the cap from the reservoir and add the appropriate coolant mixture, usually a 50/50 mix of antifreeze and water. Always check the fill level markings on the side of the reservoir to avoid overfilling, and secure the cap tightly after adding the coolant.
