What is coolant?<\/h2>\n

Coolant<\/strong> (or heat transfer fluid) is a liquid specially formulated to protect engines in intensive service, where only a third of the energy produced by fuel combustion is converted into power. Part of the excess heat is rejected as exhaust gases, while the remaining third remains trapped in the engine block. This is where the coolant comes in , absorbing this residual heat and transporting it to the radiator, where it dissipates, without harming the environment.<\/strong><\/p>\n

Composed of water, glycol and corrosion inhibitors<\/strong>, coolant resists water’s natural tendency to boil and evaporate. Thanks to its composition, it also protects the engine against extreme cold (antifreeze).<\/p>\n

However, not all coolants offer the same level of antifreeze protection<\/strong>. Some types of coolant may contain proprietary additives to prevent tart and dirt build-up, or offer additional anti-corrosion protection.<\/p>\n

In an internal combustion engine, the coolant evacuates heat, cools the engine and protects against local overheating<\/strong>.<\/p>\n

It also ensures rapid<\/strong> engine warm-up for improved efficiency. On an electric vehicle, it plays an essential role in cooling the batteries, which are particularly sensitive elements that need to be monitored in view of the technological and economic stakes involved.<\/p>\n

Finally, coolant is widely used in industries using thermal processes for cooling or heating<\/strong>. In the latter case, the coolant is present in particularly large quantities, up to 30,000 liters.<\/p>\n

So, as well as facilitating heat transfer, coolant offers protection against freezing, corrosion and boiling over, and contributes to chemical stability<\/strong>.<\/p>\n

Coolant tends to lose its qualities<\/strong> over time, weakening parts of the circuit. It is therefore essential to follow it. It is equally recommended for new electrical equipment, where it plays a key role in preventing battery overheating.<\/p>\n

Coolant analysis<\/strong> enables us to determine and control<\/strong> all its properties and characteristics<\/strong>, and to check its quality and stability<\/strong> over time, in order to avoid breakdowns.<\/p>\n

As a reminder, coolant tends to lose its qualities over time, which can damage parts of the circuit.<\/p>\n
