Why Does Water Spray Out When Opening the Radiator Cap?
1 Answers
Generally, this is due to thermal expansion and contraction, which is a normal phenomenon. Below is relevant information about diesel radiators: 1. Function: To cool the engine's water. In summer, it's necessary to switch to summer antifreeze coolant for cooling purposes. The boiling point of antifreeze is around 108 degrees Celsius, higher than that of water, preventing overheating. In winter, winter-specific antifreeze should be used to ensure it doesn't freeze outdoors while still providing cooling. Higher-grade antifreeze should withstand temperatures as low as -60 degrees Celsius. 2. Cleaning Method: First, prepare a cleaning solution with 30 kg of water, 2.5 kg of caustic soda, and 0.6 kg of kerosene, then pour it into the radiator. Start the diesel engine and run it at medium speed for about 10 minutes before shutting it off. After 10 to 12 hours, restart the diesel engine and run it at medium speed for another 10 minutes before shutting it off again to drain the cleaning solution. Add clean cooling water, start the diesel engine, and let it run at medium speed for self-cleaning. Repeat this process 2 to 3 times to completely remove scale buildup.
