Nissan Repair: stupidity, windshield wiper fluid, nissan xterra

Question
I accidentally put about 1/4 oz of windshield wiper fluid in my coolant (it was diluted in water)  can I drive my car?  did I do permanent damage? I have a 2001 Nissan Xterra

Answer
Not a problem and you can drive it.  I would change the antifreeze out since it is a 2001 model.  Change the antifreeze and replace with a 50/50 mix of antifreeze and distilled water.  Do not power flush the engine as you will blow the heater core.  Just drain and fill with water.  Run it until hot and drain it again.  Then, fill it with 50/50 mix...
