In the winter, especially if you live in a cold-weather climate, it is of utmost importance to keep your vehicle’s anti-freeze at the proper levels. If it is not, you run the risk of water freezing in your engine and causing catastrophic damage.

The same logic then would seem to apply to your windshield washer fluid. If it is mostly water and could easily freeze and burst hoses, why not add anti-freeze to the washer fluid reservoir? It only cost a few dollars and could save a ton in repair costs.

In this video, Pat Goss reveals if adding anti-freeze to washer fluid is a sound or foolish idea.

So, now you know what to do with your washer fluid when the weather gets cold.

You have questions, Pat Goss has answers.

Do I need to add anti-freeze to my windshield washer fluid during the winter?

Well, that’s absolutely false up to a point. See, back in the day when this classic was a car, windshield washers were actually optional. A lot of cars didn’t have them, but all cars have them today.

Now this business of taking anti-freeze like you would put in the radiator and putting it in the windshield washer – not a good idea at all! See, anti-freeze often can damage paint. So although it would keep the washer system from freezing, it could do a lot of damage to the car.

So what do you do? Well there are summer blends of washer solvent and winter blends of washer solvent. You want to get all the summer blend out of there, and get the freeze protecting winter blend in there to keep the washer system from freezing up and you’re good to go.
