1. First, open the hood of the car. Every car has a kettle full of antifreeze. Find the kettle with a scale line on it and see where the scale line is at the root of the liquid level. If the liquid level is lower than the scale line, it must be insufficient antifreeze;
2. When you come down, you need to see if it leaks antifreeze. If it leaks badly, you will find water under the engine on the ground. If you touch it with your hands, it's red and oily. It may be antifreeze. Go down and fix it directly;
3, sometimes it is difficult to find it with the naked eye in a short time, so this small method is needed, especially for people who don't know about cars. Sometimes engine overhaul is cylinder explosion caused by lack of antifreeze;
When parking at night, put a newspaper under the engine and check it the next day. If there is oil and water in the newspaper, you can be sure that antifreeze is leaking. The leaked antifreeze detected by this method is generally a small leak, which can be opened in a short distance, but it should be repaired as soon as possible;
If there is no oil and water in the newspaper the next day, add some antifreeze to the car and add it to the bottom of the pot at most. You can't fill it. Wait a minute to see if it's gone.
