Here in this video we are about to see how windshield wiper fluid is being changed. Open the car and look for the symbol which is on the cap of the reservoir. Remove the cap. Now pour the wiper fluid into the reservoir. The wiper fluid used varies from deicer to detergent. People tend to use the water which might turn bad once the temperature drops below a certain degree. So the water freezes ultimately the system stops making it a useless one. So the fluid is filled till it reaches the top of the reservoir. Then the cap is back on. The place to find this arrangement is the side of the walls along the perimeter of the engine. That's it we learnt a step in maintaining our car.
