Hello..

I have a 2013 Impala LTZ. I live in SoCal but go back to Colorado quite often. Several times now my windshield washer fluid becomes frozen at below freezing temperatures. This is no fun when you are driving on wet and or snowy slush roads.

The fluid I use is SUPPOSED to be good to -20 degrees F.

Anybody else have this problem? Yes I have searched the forum and not found this issue.

I am thinking of putting some 12V heat trace on the supply hoses to the nozzles and tying it into the rear heat defroster circuit.
Might overload the circuit with this approach?

Any other ideas out there?

Thanks...
Don

Whatever your buying listed as -20f fluid maybe ain't.

If you've mixed it with some "non" winter stuff it will freeze. The reservoir holds quite a bit, better than 4L I think.
It's easily diluted. If you have only used a partial jug of it and the rest is non winter it may freeze easily. You can add some isopropyl to your tank to try and increase the freezing point until you can add enough of the winter product to keep it from freezing.

I buy the -25 or -30 stuff when I can.

-20 should be fine for most uses. For you, I would drain it and buy some decent fluid (Prestone or some other recognizable brand). I use generic and have no issues, but apparently whatever you are using is inferior. Something else I do once in a while - if we have steady temps below zero, is throw a capful or two of rubbing alcohol in there too - no idea if it works, but just something I do....such a small amount in a full reservoir isnt enough to damage anything it sprays on.

EDIT: I see Pauly basically said the same thing - including the use of alcohol...

One thought I had is to keep the area around the nozzles cleared off on the hood or cowling. My theory is that snow and ice may wick into the nozzles and then freeze thereby clogging them up even tho you have ant-freeze washer fluid.
