Yes it can, as long as the engine is running. Be careful when taking the radiator cap off thou, cause its under pressure.
If it has never had any water/coolant added, then no it doesn't require antifreeze.
Doubtful !... The antifreeze is added to the radiator - to keep the water above freezing point. There is no way of the engine knowing how much antifreeze is circulating.
. Solubility _____,
Antifreeze helps the engine run cooler in the hot months and prevents the coolant from freezing in cold weather.
In countries which have a winter season ALL cars should have the correct amount of antifreeze added to their coolant fluids. If this is not added and the fluid freezes the expansion of the ice will crack the engine block.
If you start and warm up your engine: 1) The oil gets very foamy and mucky, and does not circulate through the engine properly. 2) The water in the antifreeze can heat up until it turns to steam, which expands with great force, and breaks some part of the engine. It's best to have the oil changed. That will empty the engine of the oil and antifreeze mix.
It doesn't matter,
it keeps you warm.
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.
It is a noun (a liquid substance) but may be used as a noun adjunct (e.g. antifreeze spills).
There is a reservoir container marked "coolant" in the engine compartment. Add a mixture of 50% antifreeze and 50% water. (If you use "50/50" or "pre mixed" antifreeze, DO NOT ADD WATER). Let the engine get warm and fill to the full line.
Yes, if you drained it out before starting it should be ok.
