It was found that coolant temperature increased by almost 20 °C (36 °F) during the first four hours, regardless of the initial temperature. Four tests were run at ambient temperatures ranging from −29 to −11 °C (−20 to 12 °F); continued use of the heater for up to two hours more only further increased the temperature by up to 3 °C (5 ...

However, once water boils, it is an insulator, leading to a sudden loss of cooling where steam bubbles form. Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done. An engine needs different temperatures.
Once the optimum operating temperature is reached, the thermostat progressively increases or decreases its opening in response to temperature changes, dynamically balancing the coolant recirculation flow and coolant flow to the radiator to maintain the engine temperature in the optimum range as engine heat output, vehicle speed, and outside ...
A DuPont R-134a refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again.
The BPVC was created in response to public outcry after several serious explosions in the state of Massachusetts.A fire-tube boiler exploded at the Grover Shoe Factory in Brockton, Massachusetts, on March 20, 1905, which resulted in the deaths of 58 people and injured 150.
IEC 60737 Nuclear power plants – Instrumentation important to safety – Temperature sensors (in-core and primary coolant circuit) – Characteristics and test methods; IEC 60738 Thermistors – Directly heated positive temperature coefficient; IEC 60740 Laminations for transformers and inductors
Lead-bismuth eutectic allows operation at lower temperatures while preventing the freezing of the metal coolant in a lower temperature range (eutectic point: 123.5 °C / 255.3 °F). [ 4 ] [ 6 ] Beside its highly corrosive character, [ 4 ] [ 5 ] its main disadvantage is the formation by neutron activation of 209
