Carbon dioxide is used in Magnox and AGR reactors. Helium has a low tendency to absorb neutrons and become radioactive. Inert gases are used as coolants in gas-cooled nuclear reactors. Hydrogen-cooled turbogenerators are currently the most common electrical generators in large power plants. Its thermal conductivity is higher than all other gases, it has high specific heat capacity, low density and therefore low viscosity, which is an advantage for rotary machines susceptible to windage losses. Hydrogen is used as a high-performance gaseous coolant. Air cooling uses either convective airflow (passive cooling), or a forced circulation using fans. The latter, when used to achieve below- ambient temperature, is more commonly known as refrigerant.Īir is a common form of a coolant. This coolant can either keep its phase and stay liquid or gaseous, or can undergo a phase transition, with the latent heat adding to the cooling efficiency. It has varying oil content from nil oil (synthetic coolant). Water-soluble coolant is oil in water emulsion. Industrial cutting fluid has broadly been classified as water-soluble coolant and neat cutting fluid. While the term "coolant" is commonly used in automotive and HVAC applications, in industrial processing heat-transfer fluid is one technical term more often used in high temperature as well as low-temperature manufacturing applications. Some applications also require the coolant to be an electrical insulator. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert and neither causes nor promotes corrosion of the cooling system. Check the wiring to be sure nothing is loose or corroded.Substance used to reduce or regulate the temperature of a systemĪ coolant is a substance, typically liquid or gas, that is used to reduce or regulate the temperature of a system. Your problem also be a faulty coolant level module. Also watch below your car for any telltale drips.

That may be an indication of a leak that you haven’t seen yet. While you drive, take note if you smell coolant.
COOLANT SYMBOL CRACKED
You may not notice the difference at first, thinking that your tank is fullĪ repair to a cracked engine block or head gasket is an expensive repair.
COOLANT SYMBOL CRACK
When you get a crack in the block or the intake gasket you will leak coolant and oil, usually slowly at first. Your coolant light might be signs of a more major engine problem. If you recently had your thermostat replaced, check to see that it was replaced with the correct temperature range. Your thermostat may be stuck open and causing improper readings. You may have some sensor problems that stem from the thermostat rather than the sensor. Replacing a sensor that is starting to show extreme signs of age and wear can prevent future problems. It is not a bad idea to keep an eye on your sensor’s readings. If your car is older, the sensor has deteriorated with time and may be failing but not entirely failed.

More often than not, though, you will need to take voltage and resistance readings from the sensor to see if it is functioning properly. In this case, removal and replacement is necessary. You will be able to see if it is cracked or badly corroded.

Visual diagnoses can sometimes detect a problem with the sensor. Have all of your connections checked to see if this may be the source of your problem. It is likely that the problem may be a loose, corroded, or faulty connection and not a problem with the sensor itself. A bad coolant sensor may cause a decrease in fuel efficiency or it may also cause the vehicle to fail your emissions inspection. Your sensor may fail or it may simply give a bad reading.
