Suggestions needed for siphoning out windshield wiper fluid

About 6 years ago, I was driving on the highway on a snowy day in the morning at around -25 to -30C. I pulled eventually needed to pull the wiper fluid to clear the slush/dirt. The cheap -40 degree fluid splattered on the windshield but immediately frosted up. I could barely see enough to get off the highway. It was dangerous.

That day I immediately went home and bought an expensive quality winter wiper fluid. I simply pulled the wiper to spray and drain out the existing fluid. When the wiper fluid tank was just about empty, I added in or diluted some quality fluid and sprayed it out again. I stopped pulling the wiper after 2-3 time cycles and filled the rest up with the better fluid.

Long story short, I simply drained it by pulling the wiper spray. You can probably use a combination of the siphon and wiper spray. I normally use 3/4 of a jug a year due to Canadian winters. The wiper spray motor should be to take some abuse.

 

Do you own a shop vac?

If so:

His idea is brilliantly simple!

 

I just did exactly what you plan. We were headed north and didn't know how cold it might get. I used a 6' piece of clear tubing from the hardware store. It took a couple tries to get a solid enough stream to keep the siphon going, but once it was working, it did great.

The tricky part was knowing when the tube was at the bottom of the washer tank and not feeding in so much tube that it would curl back up toward the top of the tank. What I ended up doing was feeding in the tube along with the washer fluid "dipstick." By pushing them down together, I knew that I was as close to the bottom as I was going to get when the dipstick hit bottom. Once I figured out that little trick, it was a smooth operation.

 

Simply pulling a tube connection on the output side of the pumps usually causes fluid to drain out, quite rapidly, by gravity. Whether it reconnects and seals nicely so far for me yes but the older the tubes the less likely...
