Where to fill radiator with coolant on Mazda mx-3?

To fill the radiator with coolant on a Mazda MX-3, open the hood and locate the radiator cap, which is typically at the front of the engine bay. Ensure the engine is cool before removing the cap to avoid burns. Pour the coolant into the radiator until it reaches the appropriate level, which is usually marked inside the neck of the radiator. Additionally, check the coolant reservoir and fill it as needed.
