8/18/2023 0 Comments Coolant for car wikiThe main difference between the two types of coolants is that water has rust inhibitors, while antifreeze does not. Twin cooling systems are common on diesel engines as well as some V8s which use both heads for cooling instead of one. ![]() This is called a “twin-cooling” system and can help prevent leaks because of how close the two radiators are together. On top of that, some engines actually have two radiators in order to keep coolant separated. Antifreezing also helps lower temperatures below what the engine could reach without additional cooling like a radiator or body of the car. To combat this problem, some engines use a mixture of water and antifreeze which does not evaporate as quickly when hot and can maintain proper circulation even after prolonged high RPMs or intense heat from the sun. The reason for this is that water does not evaporate well at high temperatures so after prolonged RPMs or hot weather driving, the coolant can become too thick to circulate properly. What you may not know though is that some engines actually use both! The most common form of cooling is with water, but there are other coolants like propylene glycol which can increase engine performance in hot weather or when the car is at high RPMs for long periods of time. ![]() Most car engines today are liquid-cooled, meaning they use a liquid coolant to absorb heat and dissipate it through a radiator.
