During continuous operation with large loads and long distances, the truck engine always has to work under high temperature and high pressure conditions. The cooling system thus plays an important role in maintaining a stable state for the engine and limiting damage. Choosing the right solution not only helps to increase the efficiency of heat dissipation but also protects the metal details in the cooling system. Therefore, understanding the types of truck cooling water Current efficiency is a necessary step for users and units operating heavy load vehicles.
1. Introduction to what is truck cooling water?
truck cooling water A specialized solution used in the engine cooling system to control the temperature during operation. When the truck operates with large loads and prolonged operating time, the engine generates a very large amount of heat. If not transmitted and dissipate heat in time, high temperature can directly affect the working performance and durability of mechanical parts.

In the forced circulation cooling system, the cooling water is pumped continuously through the engine body and the water tank to absorb excess heat, then transmitted to the outside environment. As a result, the engine always maintains a stable working state, limiting overheating or sudden stop of the machine when operating long distances.
Composition of truck cooling water Usually includes purified water, glycol (ethylene glycol or propylene glycol) and anti-corrosion and anti-scaling additive system. These components help the solution maintain good heat transfer capacity, limit deposits in the pipeline and protect the metal surface in the cooling system.
Choosing the right type of coolant and periodic inspection helps ensure the cooling system works stably, while contributing to prolonging the engine life and reducing maintenance costs during truck exploitation.
2. Types of effective truck cooling water today
Currently on the market, truck cooling water It is mainly classified according to the anti-corrosion technology used in the solution. Understanding each type helps users choose the right product for their vehicle.

Inorganic Acid Technology
IAT technology coolant is a solution that uses inorganic additives to create a protective film on the metal surface in the cooling system. This type of solution is usually green or blue and is commonly used on older trucks or engines made from traditional cast iron, copper or alloys.
The advantage of IAT coolant is the ability to quickly create a protective layer for metal parts immediately after being put into use. At the same time, the product has a reasonable cost and is easy to find in the market. However, due to the coating mechanism, the solution easily forms residue during long-term operation and needs to be replaced periodically for about 2-3 years or about 40,000 km depending on conditions of use.
Organic Acid Technology
OAT technology coolant uses organic additives to protect the cooling system by selective mechanism at locations at risk of corrosion. This type of solution is usually red, orange or pink and is suitable for modern trucks using many aluminum alloy details in the cooling system.
The outstanding advantage of OAT technology is its stable corrosion resistance for a long time, limiting the formation of dirt and maintaining good heat transfer performance throughout the cycle of use. In addition, the life of the solution usually lasts up to about 5 years or 150,000 km, suitable for vehicles operating continuously under high load conditions.
However, users should be careful not to mix OAT solution with other coolant to avoid chemical reactions affecting the cooling system.
Hybrid Organic Acid Technology
Active technology coolant is a solution that combines the characteristics of both IAT and OAT technology to take advantage of these two additive systems. This type of solution is usually blue or yellow and is used on trucks with cooling systems that require high performance.
Thanks to the hybrid protection mechanism between inorganic and organic additives, the active solution creates a quick protection layer for the metal surface and maintains stable corrosion resistance for a long time. This helps the cooling system to operate more efficiently under complex operating conditions.
The replacement cycle of the active coolant is usually between 3-5 years or about 150,000 km depending on actual exploitation conditions. During use, the operator should be careful not to mix with other coolant to avoid precipitation in the system.
3. How to choose the right truck cooling water

The selection truck cooling water It is necessary to rely on many technical factors related to the engine structure and actual operating conditions. Users should consider the following criteria to ensure the cooling system operates stably and long-term efficiency:
- Engine materials: Engines that use many aluminum alloy details are usually suitable for cooling water with OAT or active technology. Meanwhile, older engines using cast iron or copper materials can use IAT solution.
- Actual operating conditions: Long-distance trucks, heavy loads or continuous operation should prioritize solutions with long life and stable corrosion resistance.
- High temperature environment: In hot climate conditions like in Vietnam, the coolant needs to be able to transfer heat well and stabilize the boiling point for a long time.
- Frequency of continuous operation: Vehicles operating with high intensity should use a solution with a long change cycle to reduce maintenance time.
- Recommendations from the manufacturer: Users should refer to the technical instructions of the vehicle manufacturer to choose the right type of solution for the cooling system.
