Q: Overheating vehicle
I have a 2011 Buick LaCrosse and it's been overheating for awhile but then stopped for a couple of months. This recent week it's hot and the car has been overheating often. It's been hissing, leaking, and sometimes smoking. I've tried to find the leak since I've seen puddles on the bottom floor but have had no luck. I've smelled it in the A/C vents when I turn on the air. Does anyone have any idea to what it might be? I can't really afford a mechanic right now.
My car has 190840 miles.
My car has an automatic transmission.
