Answer and Explanation:
Most cars have a windshield wiper fluid reservoir located under the hood. The reservoir is usually clearly labeled with a picture of a windshield and wipers.
To fill the reservoir, simply remove the cap and pour in the fluid until it reaches the “Full” line on the side of the reservoir.
Be sure to use washer fluid that is designed for your car; some fluids contain alcohol or other chemicals that can damage your car’s paint or plastic parts.
