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

Heavy-Duty Truck Maintenance: The Role of Coolants

Heavy-duty trucks often operate continuously under harsh conditions and at high intensities. Therefore, maintaining equipment for optimal performance and reliability in challenging environments is always a top priority. Alongside selecting the right lubricant, an equally critical factor is choosing the correct engine coolant.

The Role of the Cooling System in Trucks

The truck's cooling system plays an essential role in overall vehicle performance. Maintenance issues in this system can account for nearly 50% of engine-related problems, such as:

• Radiator clogging due to dirt and debris.
• Insufficient coolant levels.
• Malfunctioning thermostats.

Engine Coolants for Heavy-Duty Vehicles

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

Coolants are typically available as pre-mixed solutions or concentrated formulas that need to be diluted with purified water. The recommended Ethylene Glycol/water ratio is either 30/70 or 50/50. These ratios are suggested to protect the engine from freezing or overheating.

An important aspect is the additive system in the coolant, which must provide protection against cavitation—a phenomenon that can cause cylinder liner erosion and engine damage.

Key Considerations When Selecting and Replacing Coolant for Heavy-Duty Trucks

1. Quality

• Choose a coolant recommended by the vehicle manufacturer or from reputable brands.
• Ensure the product meets high-quality standards:
  • Maintain the proper Ethylene Glycol/purified water ratio (30/70 or 50/50) to ensure effective temperature control, particularly in extreme working conditions.

2. Engine Protection

• Anti-foaming: Prevents air entrainment, which can cause cavitation and engine damage.
• Anti-corrosion: Protects the radiator and components from rust and damage.
• Engine longevity: Reduces the risk of failures and extends the durability of the cooling system.
• Note: Color is not a decisive factor when choosing a coolant.

3. Compatibility

• Assess the compatibility of the coolant with other components in the vehicle's cooling system.

4. Replacement Schedule

• Regularly inspect the coolant reservoir; if the level is low, replenish immediately.
• Drain the old coolant, flush the system, and replace it periodically every 2–3 years to maintain engine efficiency.

Selecting the right coolant not only protects the engine but also improves performance and extends the lifespan of heavy-duty trucks. Ensuring quality, compatibility, and periodic replacement keeps the cooling system stable and effective under all conditions.
