Cars use a 50/50 mix for the most part to cool the engine. 70/30, 70% anti-freeze mixes are used in places that see extremely cold temperatures <-30 degrees F. Normal temperature >-30F, cars don't use 70/30 ratio because anti-freeze is less efficient at cooling than water,. This is why most race cars use very little anti-freeze( mainly for it's lubrication properties) in their cars.

∙ 9y agoAutomotive radiators/cooling systems don't like straight water as a coolant. A mixture of at least 50% clean water and 50% antifreeze is designed to raise the boiling temp, protect the system from freezing, transfer heat energy, lubricate the water pump and adds chemicals to reduce corrosion.

∙ 9y agoMost don't use water - they normally use an ethylene glycol solution. Water (with an added lubricant for the water pump) is typically used on racing circuits, due to both the better heat transfer properties and environmental concern.
In either case, the purpose is to flow through the engine and absorb heat. It then travels through the radiator, where the heat is transferred to the much cooler ambient air which flows through the radiator fins.

Why is water used as a coolant in car radiators?
Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any other substance. That is why it is used as coolant in car radiators
What liquid is used in radiators?
Antifreeze/Coolant
Why the radiators painted black?
You can paint the radiator tanks any color you want to but don't paint the radiator core itself. Painting the core will negatively affect the radiators ability to transfer heat away from the engine coolant.
Where do you put coolant in ttr 125 motorcycle?
The TTR125 uses an air cooled engine, there are no radiators to put coolant in.
How do the properties of water contribute to its use as a coolant in car radiators?
Water alone is not recommended. It should be mixed 50/50 % (minimum) with antifreeze. This mixture helps transfer heat, keeps corrosion under control, lubricates water pump and keeps the coolant from freezing in cold climates.
Why do radiators have grooves?
That is for the air can flow through the radiator and cool the engine coolant down.
Is antifreeze added to car radiators to lower the freezing point of water?
Yes. The antifreeze/coolant also raises the boiling point and has lubricant and anti corrosive properties.
Can a solar panel run all appliances in a household?
no it just heats the water and if you want it can heat the radiators !
Engine Coolant for a 2005 suzuki drz400?
Suzuki shop manual says ethylene glycol antifreeze designed for aluminum radiators. Mix 50:50 with distilled water.
Why is antifreeze put into car radiators?
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
Why is my 1999 dodge ram suddenly overheating but the heater blows cool air?
This is typical of an engine being low on coolant in the radiator, check your radiators coolant level and fill it.
Why do radiators stay cold at the bottom?
That means that the radiator is stoped up with trash and engine coolant is not flowing through the radiator.
