I think I have a leak in my radiator because water came pouring out from under my car mazda 6s 2002. The only thing is when I opened my coolant cap it was still full. What could be the problem
Was the A/C running prior to this? It could be condensation from the A/C. Coolant tends to be pretty green and smelly so you'd have little trouble mistaking it for water.
The other option, as mentioned by mikes, is that you have a hole in your windshield cleaner bottle.
