Correct replacement cycle and misconceptions of heavy-duty truck coolant

1, Correct replacement cycle for heavy-duty truck coolant
The standard replacement cycle for conventional engineering heavy-duty trucks, tractor trailers, and dump trucks is every 2 years or 40000 kilometers, whichever comes first. For overseas working conditions such as high temperature, high load, and continuous operation in Africa, the Middle East, and Southeast Asia, it is recommended to shorten the cycle and completely replace it every 1.5-2 years.
Vehicles with long-term heavy loads, mountainous climbing, and frequent idling will experience faster coolant aging, and their anti freezing, anti boiling, and anti rust capabilities will continue to decline. Regularly replacing the coolant can ensure smooth circulation of the cooling system, effectively avoiding faults such as hot pot boiling in summer and pipeline freezing and cracking in winter.
2, The Four Most Common Misconceptions in Daily Use
Misconception 2: Mixing different colors and brands of coolant
Misconception 3: If the coolant does not change color, there is no need to replace it
The coolant appears clear, but the internal anti-corrosion and anti boiling additives have long been depleted and ineffective. Failed coolant cannot protect the metal waterway, which can easily cause internal corrosion of the engine and leakage of the water tank, belonging to the "invisible damage to the car". By the time a high-temperature fault occurs, the damage is irreversible.
Misconception 4: Only replenishing without replacing, long-term failure to drain old liquid
Many drivers only add new fluid and do not completely replace it. The mixture of new and old fluids dilutes the performance of the original solution, greatly reducing its anti-corrosion, antifreeze, and high-temperature resistance effects, resulting in the cooling system being in a sub healthy state for a long time.
3, Correct maintenance tips
When replacing the coolant, it is recommended to thoroughly clean the water tank and waterway to remove scale and impurities; Maintain sufficient liquid level in daily life and regularly check whether water pipes and pumps are leaking water; Priority should be given to using high boiling point long-acting coolant in high-temperature areas, suitable for heavy-duty continuous operation, and reducing high-temperature faults of heavy trucks from the root.
Summary
The maintenance of coolant is not about adding more, but about periodic replacement and standardized use. Avoiding misunderstandings such as adding water, mixing, and using beyond the expiration date can effectively protect the engine cooling system, allowing heavy trucks to operate stably under high temperature and heavy load conditions overseas, significantly reducing the maintenance cost of the fleet.
