The Role of Proper Coolant Maintenance in Heavy-Duty Truck Performance

Coolant, also known as antifreeze, plays a vital role in heavy-duty truck engines. It helps regulate the temperature of the engine by dissipating heat and preventing it from overheating. The coolant also protects the engine from corrosion and rust, lubricates the water pump, and prevents freezing in cold weather conditions. Therefore, maintaining proper coolant levels and quality is critical for the truck's performance and longevity.

Make sure that coolant is filled up at all times 

The first step in proper coolant maintenance is to ensure that the coolant level is always within the recommended range. The coolant level should be checked regularly, especially before long trips, and topped up if necessary. Low coolant levels can cause the engine to overheat, leading to engine damage, breakdowns, and costly repairs. It is also essential to check for leaks in the coolant system, such as radiator hoses, water pump, and thermostat housing. Leaks can cause a loss of coolant and lead to engine overheating, which can cause severe damage.

Receive coolant flushes as required 

The quality of the coolant is another critical factor in heavy-duty truck performance. Over time, coolant can become contaminated with debris, rust, and other particles. Contaminated coolant can cause clogging and corrosion of the engine's cooling system, which can lead to overheating and engine damage. Therefore, it is essential to flush and replace the coolant regularly according to the manufacturer's recommendations. The recommended interval for coolant replacement varies depending on the truck's make, model, and age. However, a general guideline is to replace the coolant every two to three years or every 30,000 to 50,000 miles.

Pick the right coolant 

It is also crucial to use the recommended type of coolant for your heavy-duty truck. Using the wrong type of coolant can lead to engine damage and void the manufacturer's warranty. Different types of coolants are available in the market, such as organic acid technology (OAT), hybrid organic acid technology (HOAT), and inorganic acid technology (IAT). Each type of coolant has its properties and is designed for specific engine types. Therefore, it is crucial to consult the owner's manual or a qualified mechanic to determine the right type of coolant for your heavy-duty truck.

Be mindful of additives 

Another aspect of proper coolant maintenance is the use of additives. Additives can enhance the coolant's properties and prevent corrosion, rust, and scaling. Additives can also improve the coolant's performance in extreme weather conditions, such as hot summers or cold winters. However, it is essential to use the recommended additives for your heavy-duty truck's coolant system. Using the wrong type of additives can cause engine damage and void the manufacturer's warranty.

Final words

Now that you have learned the importance of prioritizing coolant maintenance for your heavy-duty truck, it is vital to consider other measures that contribute to optimal truck performance. Alongside proper coolant maintenance, regular oil changes, air filter replacements, and tire rotations play a crucial role in maintaining the engine's health, fuel efficiency, and overall safety of the vehicle. Adhering to the manufacturer's recommended maintenance schedule and keeping a maintenance log can assist in tracking and prioritizing necessary tasks. By conducting regular maintenance, you can identify and address minor issues before they escalate into significant problems, mitigating the risk of breakdowns and expensive repairs.
