Antifreeze is commonly consumed due to its sweet taste cause by the ethylene glycol, [38] and is also commonly consumed as a surrogate alcohol due to its high alcohol contents. To prevent consumption due to taste, many brands have bitter additives, but many [ 39 ] [ 40 ] [ 41 ] studies do not support the idea bitter additives reduce ingestions.
The coolant used in many liquid-cooled engines must be renewed periodically and can freeze at ordinary temperatures thus causing permanent engine damage when it expands. Air-cooled engines do not require coolant service, and do not suffer damage from freezing, two commonly cited advantages for air-cooled engines.
Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.
These gases then escape into the coolant and create air pockets. Sometimes these air pockets can get trapped in the engine's coolant thermostat, causing it to stay closed and cause further overheating, thereby creating more voids between the gasket and the engine. Other times these air pockets can also cause the engine to expel coolant into the ...
An overflow tank that runs dry may result in the coolant vaporizing, which can cause localized or general overheating of the engine. Severe damage may result if the vehicle is allowed to run over temperature. Failures such as blown head gaskets, and warped or cracked cylinder heads or cylinder blocks may be the result. Sometimes there will be ...
Water can be introduced from the boiler or in a cold engine, steam will condense to water on the cool walls of the cylinders and can potentially hydrolock an engine. This is just as damaging as it is to internal combustion engines and in the case of a steam locomotive can be very dangerous as a broken connecting rod could puncture the firebox ...
The National Association of EMS Officials recommends "Cool First, Transport Second" for patients whose body temperature is over 104 degrees.
Once this key component of the cooling system had failed, overheating ensued. A second cause of engine trouble was the lack of attention to corrosion inhibitor in the coolant. The block was made from iron and the heads from aluminium, a combination that required the use of corrosion-inhibiting antifreeze all year round.
