Some models are very simple to dismantle and even need to be replaced every 5000 kilometers. Therefore, it is advisable to replace it according to the official maintenance schedule of the vehicle.

Antifreeze Many vehicles are equipped with long-lasting antifreeze at the factory, and they can be used for more than 10 years and more than 100,000 kilometers. Under normal circumstances, when there is no sediment or floe in the antifreeze, you do not need to replace it.

Brake Fluids Brake fluids are usually recommended by automobile manufacturers for replacement in 2 years or 40,000 kilometers. Of course, they can be extended to 3 years or 60,000 kilometers. For general models, choose DOT4 brake fluid.

The battery life of a typical battery is usually around 2-3 years, but it can be maintained for a longer period if properly maintained. If you feel that it is going too hard, you should pay attention to whether the battery should be changed.
