So it's dark and I'm in a hurry to get up to church to make Thanksgiving care packages and I put RainX 2-in-1 winshield washer fluid in my 2011 traverse in the wrong spot. I'm assuming that I put it in the coolant. Looked just like the darn windshield tank. What do I do? I haven't started the car yet. I'm to afraid. I put almost 1/2 gallon in. I'm outside of St. Louis and we are in a cold spell if that makes a difference. I actually have a scheduled oil change at the dealers tomorrow at 11 am.
