Maintenance method of car water tank

1. Prevent cars from "opening pots" Car water tanks are most afraid of boiling pots, that is, the temperature is too high, and you should be optimistic about the temperature displayed on the dashboard when driving.Once you find that the temperature is too high, you should stop for inspection. If the car tank is smoking, you should stop and check it decisively.

2. How should the water tank of the car be maintained? Use a special freezer. When choosing or using a freezer, you should use soft water or neutral reagent. In general, you should use a special reagent, and you can't use acidic or alkaline, otherwise it will cause corrosion.

3. Don't try to continue driving, so as not to cause major damage accidents. Do not try to open the lid of the water tank, otherwise it is likely that hot liquid will spew out and cause burns. Do not pour cold water on the engine cylinder block and cylinder head, which is likely to cause the cylinder block to burst due to sudden cold.

4. Tips for the maintenance of the car cooling system Cooling system: The most common failure of the car cooling system is that the "water tank" is broken, resulting in the loss of water.With the loss of water, and failures such as boiling the water tank and accelerating powerlessness.

Where is the car water tank (the position of the car water tank)

The car water tank is on the inside under the front cover of the vehicle, close to the position of the engine. The car water tank generally refers to the radiator. The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system consists of three parts: water inlet chamber, water outlet chamber, main piece and radiator core.

Generally, the water tank is behind the air condenser. When the engine compartment is opened, we can only see the top cover of the water tank. Only by removing the bumper at the front of the vehicle can we clearly see the location of the water tank. Behind the water tank is a cooling fan, which is used to expand the air flow for better expansion.

The car water tank is under the hood of the vehicle.The car water tank is located under the hood of the vehicle. When you open the hood, you can see the water tank cover. There is generally a warning word "high temperature danger" on the water tank cover, which is equipped with antifreeze.

The water tank is in front or behind the fan. Because the fan dissipates heat to the water tank, the water tank of the car is mainly composed of radiator core, water pipe, heat dissipation air blades, upper water tank and lower water tank, etc.

How to judge the leakage of the car water tank

1. Check whether the water tank is closed: Sometimes the water tank cover will be loose because the car often bumps. If it is checked normally elsewhere, check whether it is loose. Check whether there are traces of emulsification in the engine oil: open the engine oil cover, and if there are traces of emulsification in the oil, replace the engine cylinder pad.

2. Add water to the water tank. Fill the vehicle tank with water, wait for a period of time, observe whether the liquid level drops, and then observe whether there is water on the ground of the parked vehicle. If the liquid level drops or there is water on the ground, it means that the water tank is leaking and needs to be repaired in time. The water tank is filled with gas.

3. If the car judges that the water tank is leaking, first check whether the water tank cover has been fastened and tried to fill the gas.Enter the water tank and see where the water in the tank seeps out when it is under pressure. Unscrew the cover of the engine oil to see if there are traces of oil emulsification. If so, disassemble the engine and replace the cylinder pad.

4. Inspection method for water leakage in the car water tank: first, check whether the water tank is tightly closed, check whether the oil has emulsification marks, check whether the water tank hose is leaking, then check whether the quality of the water tank is good enough, and finally check whether the water tank hose joint is leaking. Check whether the water tank is closed. Sometimes, because the car often bumps, the water tank cover is loose.

5. The performance of water leakage in the car water tank is that the engine temperature is too high, resulting in serious mechanical accidents such as insufficient power, increased wear, damage to the cylinder pad, and even burning tiles and pulling the cylinder. Possible causes and solutions for water leakage in the car water tank: The water tank cover is not tightened, just tighten it.
