That said, it’s important to refill your wiper fluid when you see the warning light on your dash, or if you’re not getting much fluid when you try to use it. Learning how to refill windshield wiper fluid is incredibly simple to do right at home! Get the job done today with the help of our service team in the guide below.

Where to Fill Windshield Wiper Fluid

Before getting into how to refill windshield wiper fluid, you’ll need to know where to put windshield wiper fluid. Pop the hood, then look for a translucent reservoir with a cap on top. This is the wiper fluid reservoir, and it’s usually situated close to the engine. You’ll know it’s the correct reservoir by the windshield symbol. Next, follow these quick steps for how to fill wiper fluid:

1. Unscrew the cap on top of the reservoir. 
2. If you have a funnel, use it to help pour the new wiper fluid into the reservoir. Without a funnel, pour the fluid slowly so it doesn’t spill. Be careful not to overflow the reservoir — only fill it up to the line.
3. Once full, replace the cap on the reservoir and you’re good to go!

What is Windshield Wiper Fluid?

Windshield wiper fluid is specially formulated to clean your windshield without leaving streaks or haze on the glass — this is why you cannot replace it with household cleaner or soap. Typically, wiper fluid contains ethanol or methanol, as well as a minimal amount of ethylene glycol to prevent freezing in extreme temperatures. 

How to Use Windshield Wiper Fluid

Typically, the same lever you use to control the speed of your windshield wipers is what you’ll use to release the wiper fluid. On some vehicles, there’s a button on the end of the lever that you press to release the wiper fluid. If you can’t find a button, look for a wiper fluid icon with an arrow next to it. Pull or push the lever in the direction of the arrow to use your wiper fluid. When you activate the wiper fluid, the windshield wipers will automatically turn on to distribute the fluid and clean your windshield.
