All I can say is "whoops." My mind was on something else. /forums/images/graemlins/blush.gif I put about a quart of washer fluid in the engine coolant overflow tank after the squirters stopped working. I understand that most washer fluid uses methanol. Will this react harmfully with the ethelyne glycol in the engine antifreeze? Which should I do: a) leave it alone and don't worry about it. b) empty out the overflow tank and assume that not much was sucked in during the 10 mile drive. c) drain all of the coolant from the system and start over.
