It most likely has an air bubble. Allow engine to cool completely. Find bleeder valve and open to remove air bubble. This may require adding coolant. Close valve when coolant comes out. Fill reservour to correct level and go for a spin.
Yes. Never add pure antifreeze. Pure antifreeze will actually freeze before a 50/50 mix. Add coolant that is a 50/50 mix of antifreeze and distilled water. You can buy it already pre-mixed.
sounds like your thermostat is stuck closed, maybe some of the debris loosened from the flush is blocking it.
We always renew the antifreeze in our car before winter.
Antifreeze properties of some liquids were known about long before cars were invented.
It came with "Dex Cool" in it originally. (Red colored fluid). This antifreeze is responsible for softening the seals and causing intake gasket leaks on small block GM vehicles. Flush the dex-cool out as best you can and refill it with antifreeze that is designed to be mixed with either type of coolant. Mixing regular antifreeze with Dexcool unless it states on the container that it is intended to be mixed with it will cause the Dexcool to turn to jello and will plug up your system. Dexcool should be removed and flushed out COMPLETELY before adding any other type of antifreeze.
low coolant (antifreeze) Make sure the engine is cool before you open the cap and top-up the cooling system.

No. The antifreeze has to be mixed with the water before the water freezes.
I need to fill my car's radiator with antifreeze before winter comes.
no
noun.I will top up the antifreeze before we leave.Notice the definite article 'the' comes before 'antifreeze', this is a good clue to what part of speech antifreeze is.Usually we have: article + noun. eg the dog, the sunOr we have: article + adjective + noun. eg the black dog, the hot sun.
Is it at the correct fill level ? If the radiator is old it is possible some corrosion has blocked up soemwhere and the radiator may need anther draining and flush through with water till it clears out.
