How Bad Did I Screw Up?

I didn't bother to look in my owners manual to find out where to put fluid for the windshield washers after I saw Washer Water near the Green top next to the oil cap. I of course put in about 1/2 gallon and closed it up. I went for a ride today and when I pulled into the garage I noticed all liquid on the floor--about 1-2 quarts. The lightbulb went off in my head and I realized what probably happened. Is changing the anti-freeze all that is necessary or is there more to it, and if I have to change it where does it drain. Thanks for you consideration. Ed

I have seen this issue a lot with Porsches. Sometimes guys even say, "thier girlfriend/wife did it"!

Most of the time, they add about a cup or 2 but you have added a lot...1/2 gallon. The active ingredient in the washer fluid is one of the alcohols, so it will flash off. Since you added so much, I would get a flush & fill done if it was my car.

Sorry to hear that. Your Porsche coolant is specially designed to cool, protect, and (assist in) lubricate your system. Washer fluid is a mild soap which would counteract all of these things. If it was the auto store pre-mixed fluid it is mostly water anyway so you likely didn't seriously hurt anything. I agree however that an immediate flush (from a Porsche dealership or Porsche Independent) would be called for.

Thanks All. Will get that done REAL soon. Ed
