washer fluid in coolant overflow
ok so i have a dilemna here... one of the girls the works the counter at my work has washerfluid in her coolant overflow resvoire, according to the paperwork i'm the last one that did an oil change on her car 2 months ago, at which time i put washerfluid in it in the washer fluid bottle, they're trying to fire my over it which is BS... she gets her fluids checked all the time and topped off without work orders, which i haven't done for her since that oil change... i checked her car out myself and the washerfluid is sitting on top of the coolant inside the resevoir... since i got sent home, i ran a little experiment on 2 of my cars and put washer fluid in the resevoir, after about 20 miles on each car, the washer fluid had mixed into the coolant and could not be seen anymore.... so i'm wondering if anyone else would agree with me that theres no way that 2 months later the coolant had not cycled thru and pulled the washer fluid with it? i need some hard proof that someone else messed it up in the last day or so and they're just trying to throw the blame on me
