What Kind of Coolant Goes in a Semi Truck?

Semi trucks are essential for transport and freight services. To keep these heavy-duty vehicles in optimal condition, they must be properly maintained.

One important aspect of maintenance is making sure the right kind of coolant is used.

Coolant helps ensure that the engine of a semi truck doesn’t overheat and malfunction. It works by transferring heat away from the engine and circulating it throughout the cooling system. Coolant also prevents corrosion and rust from damaging key components, such as the water pump or radiator.

When selecting coolant for a semi truck, it’s important to choose a product that meets or exceeds the manufacturer’s specifications. Most manufacturers recommend using a long-life coolant that contains silicate-free extended life inhibitor technology. This type of coolant is designed to last for up to 150,000 miles before needing to be replaced.

In addition to selecting an appropriate coolant, it’s also important to choose one with the correct viscosity level for your semi truck. Viscosity is a measure of how thick or thin a fluid is; higher viscosity means the fluid is thicker while lower viscosity means it’s thinner.

For semi trucks, it’s best to use a coolant with medium viscosity (20 – 50 cSt) as this will provide adequate protection during normal operation while still allowing enough flow through the cooling system components.

Conclusion:

In conclusion, when selecting coolant for a semi truck, it’s important to choose one that meets or exceeds the manufacturer’s specifications and has an appropriate viscosity level (20 – 50 cSt). Long-life coolants containing silicate-free extended life inhibitor technology are recommended for optimal performance and protection up to 150,000 miles before needing replacement.
