How to Add Antifreeze to Shacman Heavy Trucks in Winter and Related Precautions

In winter, adding antifreeze correctly to Shacman heavy trucks is of great significance for the normal operation and maintenance of the vehicle. Here are the detailed steps and precautions.

When adding antifreeze, first, it is necessary to select the appropriate antifreeze. It should meet the requirements of the Shacman heavy truck model. Usually, the vehicle manual will provide clear specifications. For example, ethylene glycol-based antifreeze is commonly used, which has good antifreeze and anti-corrosion properties. Then, prepare tools such as a funnel, protective gloves, and goggles. The protective gear is to prevent direct contact with the antifreeze, as it may contain harmful chemicals.

Locate the antifreeze filler port in the engine compartment. The antifreeze reservoir is usually a translucent plastic container with “MAX (maximum level)” and “MIN (minimum level)” markings. In models like the Shacman X3000, the reservoir is relatively conspicuous, close to the front of the engine.

If it is the first addition or a replacement of the old antifreeze, drain the old antifreeze first. There is a drain bolt at the bottom of the vehicle. Open it to allow the old antifreeze to flow out. Ensure the vehicle is on a level surface and have a suitable container ready to collect the old antifreeze. This operation should be carried out when the engine is cool to avoid being scalded by high-temperature antifreeze. After that, slowly pour the new antifreeze into the reservoir using a funnel, being careful not to exceed the “MAX” mark.

During the use of antifreeze, several precautions should be noted. Regularly check the antifreeze level. It is recommended to check it once a week or before each long-distance driving. If the level is below the “MIN” mark, add antifreeze in time. Otherwise, the engine cooling system may not work properly, leading to overheating and potential engine damage.

Also, check the performance of the antifreeze regularly. The antifreeze’s antifreeze and anti-corrosion performance will decline over time and with use. Generally, it is advisable to replace the antifreeze every one to two years. Professional antifreeze testing tools can be used to check if the freezing point meets the requirements. In cold regions, the freezing point of the antifreeze used in Shacman heavy trucks should be 10 – 15℃ lower than the local lowest winter temperature.

Avoid mixing different brands or models of antifreeze. The components of different antifreezes may vary, and mixing them may cause chemical reactions, reducing the performance of the antifreeze and even resulting in precipitation or clogging of the cooling system. If it is necessary to change the antifreeze brand, drain the old antifreeze thoroughly before adding the new one.

Finally, pay attention to the toxicity of the antifreeze. Antifreeze usually contains toxic components such as ethylene glycol. Avoid contact with the skin and eyes. If accidental contact occurs, rinse immediately with plenty of water and seek medical attention. Also, prevent antifreeze leakage onto the ground during vehicle maintenance to avoid environmental pollution.

In conclusion, correct addition and proper use of antifreeze are essential for the winter operation of Shacman heavy trucks, which can ensure the reliable operation of the vehicle and extend its service life.
