my 2005 cobalt temp goes up to 220 -260 and I hear swishing water sound when I turn. I had the thermostat changed but did't help. Also had water on my passenger side a couple of weeks ago. Any Ideas about what is going on
Sounds like you have air in the cooling system from a leaking heater core. HTH. -Jim
Fill the coolant tank, run the car a little and check level again. Fill it again and keep filling until the level doesn't drop. It'll stop this sound if there is no permanent leak but if there is, you have to stop the leak first.
