Oh Boy! Just make sure you don't do it in reverse. Somebody put coolant in the washer tank of my KW and it dissolved the wipers. Pretty much blind until I was able to scrub the **** off.

Some years ago my neighbor poured 1 gallon of washer fluid into her Saturn's engine oil. A few days later the engine launced a connecting rod.

Even tho there marked, it happens all the time.
Mopar needs a better way to mark these caps I think.

This cannot be fixed, no different than people filling gas truck with diesel or diesel truck with gas happens all the time. Vehicle operator has to be smarter than the equipment they are operating! You cannot fool proff anything.
