Even though it’s as important as oil checkup, people often neglect to control the engine coolant (antifreeze). This can have serious consequences for the truck considering that the engine coolant is responsible for managing the boiling point in the summer and freezing point in the winter. What’s more, it also protects the engine from the corrosion. Essentially, engine coolant is vital in all vehicles. Still, as a trucker, you should be aware of the fact that larger vehicles such as trucks also have a much greater need for a proper coolant. Therefore, make sure that you efficiently choose your truck’s engine coolant.


Why change the engine coolant often?

The coolant needs to be changed because the chemicals in it break down and become less effective over time. This ends up generating rust and mud, which can damage the cooling system.

If your truck’s cooling system is damaged, the risk of the engine overheating becomes a lot bigger, and can ultimately cost you more money compared to a coolant change.

When it’s time to change your truck’s engine coolant, you’ll have to find the right one. The easiest way to know which one to buy is to go straight to your truck’s brand for guidance.


Mix the engine coolant

As a general rule, the engine coolant is mixed with water in a 50/50 ratio.

You should never have less than 40% of the water in the mixture. It’s often thought that the main function of the coolant is to stop the freezing of the engine, but the mixture also helps lower the freezing point and increase the boiling point, which can be much more important.

Do not use just any water, however; it must be deionized or distilled. If you mix the coolant incorrectly, it could cause rust and corrosion, as well as cavitation of the cylinder wall that would eventually damage your engine.

Also, many manufacturers recommend the use of a pre-diluted coolant.


Check the coolant level

Locate the coolant reservoir under the hood of your truck. It should be a small transparent tank with minimum and maximum lines shown on the side. If the level is below the minimum line, you must add coolant to keep your engine protected.

If your truck’s engine coolant is lacking, the engine may overheat in a matter of minutes, which will generally cause irreversible and costly damage.


Wait for your engine to cool

If you must add more coolant, remember to only do it when the engine is cold. It’s very dangerous to open the tank while it’s hot. Once cold, carefully open the lid of the tank and add the coolant until it reaches the correct line.


Replace the coolant when it’s time

The chemicals in the coolant start doing their job every time you start your truck. This fluid is pumped through your engine to maintain a uniform operating temperature and prevent corrosion. So, the longer your truck stays with the unchanged engine coolant, the less efficient this process will be.

That is why you must respect the intervals of changes and maintenance. Check the manufacturer’s recommendations to know exactly when it’s advisable to replace your truck’s engine coolant.


Bottomley Enterprises hopes to raise awareness about the importance of regular checkup and top-up when it comes to the engine coolant in one’s vehicle, and especially the truck. This can make a difference between a fully operating and out-of-order vehicle. Interested in joining forces with us? Then feel free to fill out the driver’s application on our website.
