you put winscreen wash in your coolant top up tank by mistake? (tt 225)

 

It is not going to mean immediate and severe damage if that is what you are asking. Simply have a coolant flush service done. Now if you have decided to drive on it for the last 5000 miles, it means lost cooling capability, possibility of boiling off fluid, radiator and block and head damage. How much did you put in? I mean windshield washer fluid is comparable to water so it is not that bad. But most washer fluids have a chemical to keep them from freezing that is corrosive to the aluminum (like why you cannot put in green coolant on you audi). Just drive it over to Jiffy Lube and have the radiator flushed... 50 dollar oops.

 

Damn that sucked I'll bet you were like OOOOOOOOOOOHHHHHHHHHHHH WTF did I just do.....LOL


Flush it I don't think it's a big deal unless it's in their for a while.......
