How much windshield wiper fluid should I put in my car?

Can you overfill windshield washer fluid?

Be Sure Not to Overfill

You don’t want to overfill the reservoir because it can cause many issues. Sometimes when it gets hot under the hood, due to the engine heat or outside temperature, it will cause the fluid to expand. If you overfill the reservoir, it could break the container or cause leaks.

Do you need to add water to windshield wiper fluid?

Short answer, yes, but it should be distilled water so that minerals don’t deposit in the washer system and clog it up. You should only use water if you are sure your car will stay above freezing the entire time that water is in there.

Can you put windshield washer fluid in while the car is hot?
