What kind of coolant should heavy trucks use? Points to note when choosing coolant for heavy trucks

Heavy-Duty Truck Maintenance: The Importance of Coolants

Heavy-duty trucks often operate continuously under harsh conditions and intense workloads. Therefore, maintaining equipment to achieve optimal performance and reliability in challenging conditions is always a top priority. In addition to selecting the right type of lubricant, an equally important factor is choosing the appropriate engine coolant.

The Role of the Cooling System in Trucks

The cooling system in trucks plays a vital role in the vehicle's overall performance. Neglecting its maintenance can lead to nearly 50% of engine-related issues, such as:

• Radiator clogging with dirt and debris.
• Insufficient coolant levels.
• Malfunctioning thermostatic valves.

Coolants for Heavy-Duty Trucks

The primary function of coolant is to regulate and control the engine's temperature during operation, while also preventing corrosion and rust of engine components.

Coolants are typically available in pre-mixed forms or concentrated formulas, which need to be diluted with purified water. The recommended Ethylene Glycol/water ratio is 30/70 or 50/50, ensuring protection against freezing and overheating.

An essential aspect of coolant performance is its additive system, which must provide protection against cavitation that could cause cylinder liner erosion and engine damage.

1. Quality

• Manufacturer Recommendation: Always choose a coolant recommended by the vehicle manufacturer or a reputable coolant supplier.
• High-Quality Standards: Ensure the product meets stringent quality standards, including:
  • The proper Ethylene Glycol to purified water ratio (30/70 or 50/50) to maintain effective temperature control, especially under harsh working conditions.

2. Engine Protection

• Anti-Foaming Properties: Prevents air bubbles that can cause cavitation and engine damage.
• Corrosion Resistance: Protects radiators and other components from rust and deterioration.
• Extends Engine Life: Reduces the risk of breakdowns and enhances the durability of the cooling system.

Note: Coolant color is not a determining factor when selecting a product.

3. Compatibility

• Check the compatibility of the coolant with other components in the truck’s cooling system to avoid potential damage or inefficiency.

4. Replacement Frequency

• Regular Inspection: Frequently check the coolant reservoir, and top up immediately if the level is low.
• Periodic Replacement: Drain the old coolant, flush the system, and replace it every 2–3 years to maintain optimal engine performance.

Conclusion

Choosing the right coolant not only protects the engine but also enhances truck performance and extends its lifespan. Ensuring quality, compatibility, and regular replacement keeps the cooling system running smoothly and efficiently in all conditions.
