Coolant Additive

Coolant additives are chemical substances that are added to the coolant or antifreeze in a vehicle's cooling system. They are part of the supply class Miscellaneous Chemical Specialties in the supply group Chemicals And Chemical Products.

Coolant additives are used to enhance the performance and longevity of the coolant in the cooling system. They help prevent corrosion, cavitation, and scale formation within the system. These additives also improve heat transfer and maintain the proper pH balance of the coolant.

Some common types of coolant additives include:

1. Corrosion inhibitors: These additives protect the metal components of the cooling system from corrosion caused by the coolant or water.

2. Anti-foaming agents: These additives prevent the formation of foam in the cooling system, which can hinder heat transfer and reduce the efficiency of the system.

3. Anti-cavitation agents: These additives help prevent cavitation, which is the formation and collapse of small bubbles in the coolant. Cavitation can cause damage to the engine's water pump and other components.

4. Scale inhibitors: These additives prevent the formation of scale or mineral deposits in the cooling system, which can reduce the efficiency of heat transfer.

5. pH stabilizers: These additives help maintain the proper pH balance of the coolant, which is important for preventing corrosion and maintaining the overall health of the cooling system.

It is important to follow the manufacturer's recommendations when selecting and using coolant additives, as different vehicles and cooling systems may have specific requirements.
