Correct ways to maintain cars in winter.

1, external maintenance. Maintenance engine cleaning, check whether the oil brake fluid antifreeze is insufficient. The low temperature and cold weather in winter is related to driving safety. The maintenance of automobile interior is particularly important. Oil, air filter, battery, antifreeze, spark plug, throttle, fuel injector and clutch must be inspected and maintained regularly and in time. If summer oil is used, it must be replaced.

2. Maintenance and maintenance of cars in winter. Battery life. Most car owners may only notice the existence of batteries in winter. The life of a battery is generally two to three years. If this time limit is exceeded, the battery needs to be replaced. If it is not replaced in time, the battery will leak, so it is likely to be damaged in winter.

3. Check whether the engine oil is sufficient. In winter, cars can run normally. Engine oil plays a very important role. Before winter comes, be sure to carefully check whether the oil dipstick is within the normal range, and then check whether it is time to change the oil in your car. You can refer to the maintenance manual. If it snows heavily, cover the car.

4. Replace or add antifreeze in time. The outdoor temperature is very low in winter. If the vehicle wants to run normally, it must have enough antifreeze. Otherwise, the water tank will freeze, it will not circulate normally, and the vehicle will malfunction. The antifreeze should be between MAX and MIX. It just takes time, and if it is missing, it must be replenished in time.

5. Adjust the tire pressure. It is very cold in winter. Try to ensure that the tires of the car are inflated more than in summer, because the tires are easy to expand with heat and contract with cold, so that driving is comfortable and safe. Don't refuel only when the car is warm-up, because the oil viscosity increases in winter and the circulation is slow. Four-wheel alignment is prone to snow and ice on the road in winter. At the same time, rubber, metal, plastic and other materials will harden at low temperature, and the control system will become heavier accordingly. The sense of road is weakened. Incorrect four-wheel alignment can easily affect safety. Cold weather does great harm to cars, such as breakdowns.
