Purging the cooling circuit

The coolant in a vehicle should generally be checked and replaced regularly. Why is this necessary? Simply because over time and mileage it loses its properties and qualities. Indeed, the pH level decreases, increasing its acidity and thus its corrosive action on the cooling organs.

It is also possible that air may appear in the circuit. This air makes it less efficient in transferring heat to the radiator. In this case, it is necessary to bleed the cooling circuit to eliminate the presence of air.

TO HAVE THE COOLING SYSTEM DRAINED BY PROFESSIONALS.

In order not to get into too tedious operations, it is advisable to go to a professional for a bleeding of the cooling circuit. Why should I do this? Because they are beginning to equip themselves with machines that allow them to drain, purge and replace the coolant in the image of Flash Cooling®.

This type of machine makes it possible to completely drain the circuit and check its tightness. The emptying is done quickly, because the machine will create a vacuum in the cooling circuit and fill it afterwards by vacuum and by carrying out a total draining.

The replacement operation is really simple, because you just have to connect the machine directly to the expansion tank and that’s it. In addition to being simple, the operation does not require any disassembly on the vehicle.

THE IMPORTANCE OF COOLANT

The coolant in a vehicle should generally be checked at least once every three months. For those who don’t know, it should be replaced every 50,000 kilometres or every 2 to 4 years depending on the vehicle.

Draining the coolant is important because once the coolant has worn off, problems can occur such as reduced engine performance or corrosion of engine parts. The role of coolant is to maintain a constant temperature in a vehicle’s engine. It prevents the engine from overheating and protects it from freezing.

In addition to all this, it helps maintain an ambient temperature in the vehicle’s interior. It will also protect the cooling system from corrosion. It lubricates the moving parts and protects the metal or rubber parts of the cooling system.
