Three chapters of automobile maintenance

First of all, the water in the tank

Some people like to add antifreeze to the water in the tank. The main purpose of antifreeze is antifreeze, lubrication and corrosion protection. Its principle is to reduce the freezing point by adding antifreeze solution to make the water in the water tank become a mixed solution, which is not easy to freeze; At the same time, its boiling point is relatively high, so it can also reduce the evaporation of water in the water tank and enhance the effect of cooling the engine when used in summer. In addition, antifreeze has the function of anticorrosion, which can avoid the corrosion of water tank, and lubrication, which can lubricate the bearing of water pump.

note:

When the engine and water tank are overheated, removing the water tank cover may cause steam and antifreeze to spray out, so don't open the water tank cover at this time.

Second, the wiper water

Better add a little windshield cleaner. Washing the windshield with clean water is not very effective.

note:

When using concentrated cleaning solution, add water according to the manufacturer's instructions.

◎ Do not mix the ready-made detergent with water, because tiny foreign objects in the water will block the system. Water freezes and damages reservoirs and other parts of the system.

◎ When the weather is very cold, only the cleaning liquid can be filled up, and the remaining space is reserved for expansion when it freezes to avoid damaging the liquid storage tank. Third, battery water.

How to check:

Although some batteries are maintenance-free, that is, there is no need to add water. In hot summer areas, there are still some batteries that need water. When the battery water is insufficient, there is no need to add any supplement, just distilled water. Battery water will evaporate faster in summer, so check it more every summer to prevent too little battery water from damaging the battery and reducing its life.

note:

Please don't use matches near the battery to avoid explosion. If you need to light the cabin, please also use a flashlight.

◎ If your car doesn't use waterless batteries, always check whether the battery water is enough. If it is not enough, be sure to add it carefully.
