Saturday plans are F@##, it's thanksgiving here in canada, As we were leaving i noticed two big runs on the driveway, it looked clear and smells neutral< didn"t know what it was i opened the coolant tank and saw the floating stick was broken off. So i put it back and checked again to see that there was a small paddle in the front under the fan> i stared the car to move it back and then opened the expansion tank again to see that the stick was gone . Again long weekend here need the car for the wife to take the kids and to go to work. So to all my old friends on the forum i need your help please>

Clear and neutral... doesnt sound like coolant. AC condensation, window wash, storm drains clearing a bit delayed because they are clogged? Is it collecting on the shields? Can you see it pooling when you open the hood? Does anything look to be leaking?

around the top of the rad seemed to be leaking. Not sure though because everything is covered. As for the coolant, it's the same stuff i saw inside the expansion tank.

I found leak. It was the return hose tucked under the hood. IT broke right off when i was checking it. Antifreeze all over my face thank god it wasn't too hot.
