Discover our guide to choose the right coolant for 50cc and 125cc motorcycle radiator and engine, scooter, maxi scooter, quad, moped...

Le coolant aims to resolve the harmful appearance of heat and hot spots in certain areas of the engine block.

It is an essential fluid for the operation of an engine. It circulates in the cooling circuit, absorbing the heat produced par the engine in operation, before rejecting it towards the radiator where it is evacuated into the air. Without it, the engine would overheat and suffer significant damage.

Operation and role of this fluid in the engine

Engine temperature regulation

Its main role is to maintain the engine temperature at an optimal level. By absorbing the heat produced par the operation of the engine and by transferring it to the radiator to be evacuated, this fluid prevents the engine from overheating and helps ensure the proper functioning of your two-wheeler or quad.

Protection against frost and corrosion

In addition to its cooling function, it plays a protective role against freezing and corrosion. It has a freezing temperature much lower than that of water, which allows it to remain liquid in the event of extreme cold, avoiding damage that freezing could cause to your engine. It also contains anti-corrosion additives which protect the various elements of the cooling circuit.

The different types of solutions for cooling an engine

The different acronyms

Type IAT (Inorganic Acid Technology) is the oldest and most classic coolant, green or blue in color. It is mainly composed of ethylene glycol and mineral corrosion inhibitors.

The OAT type (Organic Acid Technology), is composed of ethylene or propylene glycol and organic corrosion inhibitors. Red, pink, orange or yellow in color, this liquid offers better protection against corrosion and can be mixed with other types of liquid.

Type HOAT (Hybrid Organic Acid Technology), is a mixture of types IAT and OAT, and offers very good protection against corrosion. It is usually green, orange or pink in color.

Meaning of Cooling Solution Colors

The different colors of the coolants are not there par chance. They correspond to differences in the composition of the liquid and its properties. The color of the coolant can give an indication of the type of technology used (IAT, OAT, HOAT) and therefore its characteristics. However, caution should be exercised,ar color standardization is not systematic and may vary depending on the manufacturer.

Different Types of Coolant

To choose the right coolant, several criteria must be taken into account. Among these, the type of engine (with or without radiator, level of performance), the climate in which you use your vehicle (presence of frost in winter, high summer temperatures), and the recommendations of the vehicle manufacturer.

If there are different colors of coolant, rely more on the type of fluid listed on the container and its technology rather than the color.

Identify signs for product replacement

Visible symptoms

There may be signs that your coolant needs to be replaced. Among these, we can cite the presence of deposits in the expansion tank, a color of the fluid which becomes dull, a fluid level which drops abnormally or recurrent engine overheating.

The impact on the operation of your vehicle

Aging or improperly matched coolant can affect the proper functioning of your vehicle. This can manifest itself par higher fuel consumption, loss of power, engine overheating or even serious breakdowns.

Steps for draining and replacing

Changing the coolant requires a few steps. First, drain the used coolant, then flush the cooling system to remove any residue before adding the new fluid. This operation, although relatively simple, requires some precautions to avoid any risk of burns or contact with the skin.

ATTENTION: Never open the radiator cap to add coolant while hot. Wait for the engine to cool completely. If you do not follow this rule of caution, you risk serious burns caused byar the liquid under pressure.

Mistakes to avoid when changing

It is important not to confuse the brake fluid reservoir and the coolant expansion tank. Additionally, don't forget to check the condition of the cooling circuit (radiator, hoses, pumps) before pouring in the new liquid. Finally, make sure you respect the maximum filling level indicated on the expansion tank.

Our selection of coolants
