Pay attention to the daily maintenance and cooling skills of the car water tank

If the water tank of the vehicle is improperly handled during normal driving, it is very prone to the phenomenon of "pot boiling". Encountering such situations will delay the owner's time, and if not handled properly, it may also lead to accidents of machine damage. Today, the editor is here to introduce the daily maintenance of the water tank and the cooling technique of the high-temperature water tank. I hope it will be helpful to the majority of car owners.

Tips for cooling high-temperature water tank

When the car is driving, white water vapor suddenly comes out of the hood, or the pointer of the water temperature meter quickly rises to the position of the high temperature "H" mark, which means that the engine temperature is too high. Usually caused by insufficient water in the water tank, water leakage, or the water tank fan is not running. The processing method is as follows:

Step 1: Find a safe place to park immediately, but don't turn off the flame immediately. Keep the engine idling to continue cooling, and open the engine cover to increase the cooling speed.

Note: When the water temperature is too high or even boiled:

1. Don't try to continue driving, so as not to cause large machine damage accidents.

2. Do not try to open the water tank cover, otherwise it is very likely that hot liquid will be sprayed out and cause burns.

3. Do not pour cold water on the engine block and cylinder head, which may cause the block to burst due to sudden cooling.

Step 2: After a period of time, check for water leaks under the car.

Step 3: Wait until the pointer of the water temperature gauge drops to the proper temperature, and then turn off the engine.

Step 4: Wrap the water tank cover with a wet towel, and slowly turn on the first switch (about 1/4 turn). After the water vapor pressure is released, fully open the water tank cover, check the water volume and quality in the water tank, and the fan belt Is there any abnormality? If the amount of water is insufficient, slowly add water to the highest mark.

Note: If the water tank is leaking or the fan belt is loose or broken, you can call the towing company to wait for the trailer to rescue. If necessary, after the engine has completely cooled down, drive the car to a service plant for repair at a low speed. Remember, you can't drive at normal speed, otherwise it may cause permanent damage to the engine.

Daily maintenance methods

Generally speaking, the antifreeze should be replaced when driving for 20,000 kilometers or one year; do not add tap water when there is no antifreeze.

Rusting and scaling of the engine water tank are the most common problems. Rust and scale will limit the flow of antifreeze in the cooling system, reduce heat dissipation, cause the engine to overheat, and even cause engine damage. The oxidation of antifreeze will also form acidic substances, corrode the metal parts of the water tank, causing damage and leakage of the water tank. The solution to the trouble of the water tank is mainly a routine inspection on weekdays. You should always check the water tank for leaks or rust. Clean it on time, replace or add antifreeze to increase the boiling point and extend the service life. Generally speaking, the antifreeze should be replaced when driving for 20,000 kilometers or one year. This can increase the boiling point, prevent the formation of scale, rust and improve the heat dissipation effect, so that the pump has a lubricating effect, and avoid and eliminate the engine damage caused by the instantaneous high temperature caused by the bubbles.
