Can I Put Regular Coolant in Semi Truck?

Regular coolant is generally used in smaller automobiles such as cars, SUVs, and light trucks. Semi trucks are larger and require a much heavier duty coolant than regular coolant can provide.

Semi trucks have much larger engines, and due to their size and weight they generate a higher amount of heat than smaller vehicles. Regular coolant is not designed to withstand the extreme temperatures generated by semi truck engines, so it can break down quickly and cause major damage to the engine.

What Happens If I Put Regular Coolant in a Semi Truck?

Putting regular coolant into a semi truck can lead to serious problems if not addressed quickly. The regular coolant will be unable to handle the heat that the engine generates and will break down and become acidic.

This acidity can corrode metal components, leading to costly repairs or even engine failure. Additionally, regular coolants often contain silicate-based chemicals that are not suited for semi truck engines and can cause clogs in the cooling system, resulting in decreased performance.

What Type of Coolant Should I Use in a Semi Truck?

Heavy duty diesel coolants are specifically designed for use in semi trucks. These types of coolants contain a variety of additives that help them withstand high temperatures better than regular coolants.

They also contain corrosion inhibitors that help protect metal components from rust or other damage caused by acidic breakdowns. Heavy-duty diesel coolants are specifically engineered for use in semi trucks, so they should always be used instead of regular car or light truck coolants.

Conclusion:

It is not recommended to put regular coolant in a semi truck as it cannot handle the high temperatures created by the engine and may cause corrosion or clogging which can lead to costly repairs or even engine failure. Heavy-duty diesel coolants should always be used instead as they are specifically designed for use in semi trucks.
