Are you getting white smoke from the exhaust even with the engine warmed up ? If so , you are getting engine coolant into an engine cylinder from a bad head gasket , a warped or cracked cylinder head
No! Thermostat.

Check Antifreeze level..make sure there are no leaks under the vehicle.
Blown head gasket.
No. Antifreeze is added to the engine cooling system to help the engine run cooler and keep the water from freezing in the winter. A refrigerant (also called freon) is what makes the a/c blow cold air.
Make sure that the motor oil is not mixing with the antifreeze. That would give you that gray exhaust you're referring too. If the oil is milky, then you need a head gasket job.
Check your antifreeze or cooling level this happened to me.
buy a chip or programmer. straight pipe your exhaust.
it would make the antifreeze work more efficiently but you can. but why would you when water is free? 50/50 mixture is usually recomended
Antifreeze is usually about 1,000 dollars to make.
No
Excess should blow out the ventNot necessarily bad. Remember this next time: Just make sure that in the antifreeze overflow that its filled to the "full" line, nothing more. Also take off your radiator cap. You should be able to see antifreeze. If not, add it. - andey78
