Antifreeze
Antifreeze should generally be replaced every two to three years. If the antifreeze has been used for no more than two years and its color has not changed, it does not need to be replaced.
Power Steering Fluid
Power steering fluid is mainly checked, but there is a filter in the reservoir that needs to be replaced.
Gear Oil
Heavy-duty truck gear oil should be changed every year or 100,000 kilometers.

Engine Oil
Under normal circumstances, heavy-duty truck oil loss is minimal, but it is easily contaminated, thus losing its protective function for the diesel engine. During truck diesel engine operation, incomplete combustion of fuel produces a large amount of soot, and carbon and air deposits enter the engine oil. Mechanically, even more impurities will accumulate after trial operation. Simply adding oil without addressing the underlying issues can easily lead to accidents, such as burning tiles and axles. Therefore, truck owners are reminded that when changing engine oil, the oil passages must be thoroughly cleaned and mechanical impurities removed.

Filtration
If the oil filter is not replaced in a timely manner, excessive impurities will clog it, causing poor engine lubrication and severe wear. Furthermore, due to filter blockage, when the pressure difference between the filter's inlet and outlet reaches a certain value, the oil filter's bypass valve will open, allowing unfiltered oil to enter the lubrication system. This will accelerate the wear of engine components and form carbon deposits and gum deposits in the combustion chamber and valves, affecting the combustion of the air-fuel mixture.

Dryer Box:
The dryer box filters moisture from the air passage. The air passage remains dry in summer, but can freeze in winter! Unless you buy a new car within a year, the dryer box must be replaced; it's a matter of driving safety.

Tire Pressure:
Tire pressure generally decreases as the weather cools, requiring appropriate top-up.
Wheel Maintenance:
Focus on checking the brake pads and ABS sensor probe.
If the wheel hub axle is lubricated with gear oil, the wheel hub gear oil also needs to be checked and generally changed every 30,000 to 50,000 kilometers.

With winter approaching, roads are becoming increasingly wet and icy. Kayou needs a comprehensive inspection of its steering, braking, and cornering systems.
Chassis, suspension, and tire inspection are also necessary. Engine oils and fluids that need changing should be replaced promptly. The engine, in particular, should be carefully inspected. Any problems found should be repaired and addressed immediately.
