Frozen washer fluid

Move to Florida and it won't be a big problem....

Smartass - I live near Los Angeles but it is only a 45 min drive to snow in the mountains.

The windshield fluid for lower temperatures is best for winters - warm weather fluid has less alcohol (antifreeze) so it doesn't evaporate before you can clean the windshield. So you are probably safe in LA with "summer" I live in Redding and is 95 now and a few miles east at Lassen there is much snow. So have both types

Yes. it can burst the wundshield washer reservoir.

Why?

isn't 32degF the freezing point of water? so, is that Kmart washer fluid nothing but water?

It had the same blue color - I just had the 'false' notion that all washer fluid would be frost proof.

It's not a false notion on their part, but a false assumption on your part - there are many different formulas for washer fluid, and the only thing that most of them have in common is the blue dye. Hence the warning on the bottle that it will freeze.

They dump a bunch of alcohol or other antifreeze ingredients into the 'Winter" blend formulas so they don't freeze in the bottle.

In temperate areas that hardly ever see a hard freeze, it's all water based. They add detergents or surfactants to get the dirt loose, and leave out the alcohols and glycols that would handle the anti-freeze function.

-->--

Not if you don't suspect it will get below 32F over the use of the fluid.

During the summer time, I usually just use plain water to top off my tank. It dilutes what is already in there, and offers no freeze protection, but come colder months, I start using the fully protected stuff again.

Then that's just me, I guess.

The fluid pump is designed to pump fluids, not solids. Think about it ...
