Reading the gauge on a car air pump: Every car air pump is equipped with a small screen. This screen not only displays the preset tire pressure but also shows the real-time tire pressure during inflation. For example: When testing a tire, if the screen displays 2.5, it means the tire pressure is 2.5 BAR. Below is a related introduction on how to use a car air pump: 1. Power source: Most car air pumps draw power through the 12V cigarette lighter socket, but some can also be powered via the battery. 2. Connecting the air valve: To prevent air leakage at the connection point during inflation, car air pumps generally use a threaded tightening method to connect to the air valve. 3. Setting the inflation pressure: Set the desired inflation pressure on the tire pressure setting panel of the car air pump. 4. Starting inflation: Once everything is ready, press the inflation start button, and the car air pump will begin inflating the tire. When the preset tire pressure value is reached, the car air pump will automatically stop working.

What Causes the Battery Light to Illuminate on the Dashboard?

The main reasons why the battery light illuminates on the dashboard are: 1. Loose battery terminals. It is necessary to check the positive and negative terminals of the battery for looseness and severe oxidation, which can lead to poor contact. The battery terminals should be cleaned and tightened. 2. Loose alternator belt. The alternator belt should be inspected for looseness or slippage. If the belt is loose or slipping, it cannot charge the battery, and the battery light will illuminate. It is advisable to visit a 4S shop for inspection or repair. 3. Fault in the charging circuit system. A thorough inspection and repair of the charging circuit system should be conducted at a 4S shop.

What are the reasons for rapid consumption of car antifreeze?

There are mainly the following reasons for the rapid consumption of car antifreeze, which are: 1. Unreasonable design of the cooling system; 2. Leakage occurs; 3. Poor circulation leading to fast consumption; 4. Coolant entering the cylinder and being burned. Additional information: 1. Coolant, also known as antifreeze, is a liquid composed of antifreeze additives, additives to prevent metal corrosion, and water. 2. It needs to have properties such as antifreeze, anti-corrosion, heat conduction, and non-deterioration. Currently, antifreeze with ethylene glycol as the main component, along with anti-corrosion additives and water, is commonly used. 3. The engine cooling system of internal combustion vehicles is a liquid-cooled closed-loop system composed of cylinders, jackets, and radiators. The working condition of the cooling system directly affects the normal operation of the vehicle and its service life.

What is the difference between car coolant and antifreeze?

The differences between car coolant and antifreeze are: 1. Applicable seasons differ: Coolant refers to any liquid that can lower the engine temperature, which can be water or antifreeze. Water is limited by seasons; antifreeze is suitable for all seasons, with high quality and guaranteed performance. 2. Applicable regions differ: Coolant is suitable for the southern regions; antifreeze is suitable for the northern regions. The functions of car antifreeze are: 1. Providing anti-corrosion protection for cooling system components; 2. Preventing scale formation to avoid reducing the radiator's cooling efficiency; 3. Ensuring the engine operates within the normal temperature range. Precautions for using antifreeze: 1. The antifreeze level should be checked regularly and replenished promptly if it falls below the minimum level; 2. Observe whether the antifreeze has any turbid sediments, and replace it in time if there are; 3. Different car models have antifreeze of different colors, which should not be mixed; 4. Before winter, measure the freezing point of the antifreeze to prevent it from freezing.
