What maintenance items are required for a car after driving 20,000 kilometers?

What are the reasons for the Audi A6 wiper not working?

Wiper not working reasons are as follows: Check the wiper blades: If you usually don't pay attention to car wiper blade maintenance, you may find them severely damaged on rainy days and unable to work properly. In this case, simply replace a set of wiper blades in time. Check the wiper motor: After opening the car hood, you can see the wiper motor. You can touch the wiper motor with your hand. If it feels hot, it indicates an internal short circuit in the motor, and replacing the motor can solve the problem. Check the wiper linkage: There are many connection points in the wiper linkage. If these points have issues, the wiper won't work properly either. You can judge whether it's a linkage fault by observing the wiper's operation. Check the wiper fuse: To protect the car's circuits, each electrical device is equipped with a fuse. If the wiper doesn't work, you can check if the wiper fuse is blown. You can replace the blown fuse with a spare one from the car.

How Many Kilometers Should a Timing Belt Be Replaced?

Automobile timing belts should be replaced every 70,000 to 80,000 kilometers. Below is relevant information about automobile timing belts: The function of timing belts: The main function of a timing belt is to drive the valve train of the engine. It connects the timing pulley on the engine cylinder head at the top and the crankshaft timing pulley at the bottom, ensuring that the engine's intake and exhaust valves open or close at the appropriate times to allow the engine cylinders to intake and exhaust normally. The importance of replacing timing belts: The timing belt connects the camshaft and the crankshaft, controlling the opening and closing of the valves and the rotation of the crankshaft and the up-and-down movement of the pistons. If the timing belt breaks, the timing of the valve opening and closing and the piston movement will be disrupted, causing the valves and pistons to collide with each other. This can lead to damage to the valves and pistons, engine failure, and in severe cases, damage to the engine itself.

What is the standard illumination distance for car low beam headlights?

"There is no standard regulation specifying the exact illumination distance for car low beam headlights in meters, only requirements for the luminous intensity and beam position of headlights. However, generally speaking, a car's low beams should illuminate the road 25-35 meters ahead of the vehicle on level ground. Article 48 of the 'Road Traffic Safety Law' stipulates: On roads without central barriers or centerlines, drivers must switch to low beams when meeting oncoming vehicles at a distance of over 150 meters. Low beams must also be used when meeting non-motorized vehicles on narrow roads or bridges. When driving at night on roads without streetlights, under poor lighting conditions, or in low visibility situations such as fog, rain, snow, dust, or hail, vehicles traveling in the same direction at close distances should use low beams. When passing sharp curves, slopes, arched bridges, crosswalks, or uncontrolled intersections at night, drivers should alternately switch between high and low beams as a signal. When driving on unlit roads at night at speeds below 30 km/h, low beams may be used. For speeds exceeding 30 km/h, high beams may be used. On well-lit road sections at night, low beams should be used."

How Does a Fuel Gauge Work?

The working principle of a fuel gauge: When the fuel level in the tank decreases, the float sinks, moving the sliding arm and increasing the resistance. As a result, the current returning to the fuel gauge decreases relatively, causing the fuel gauge reading to drop. The fuel gauge consists of a thin metal rod and a float connected to the rod, with the float typically made of foam plastic. The end of the metal rod is attached to a variable resistor. A resistor is a device used to impede the flow of electric current. The greater the resistance, the smaller the current that passes through. The fuel gauge is a relatively simple device. Current flowing from the sender passes through a resistor, which may be wrapped around or located near a bimetallic strip. The bimetallic strip is connected to the fuel gauge needle via a linkage. When the resistance increases, the current passing through the heating coil decreases, causing the bimetallic strip to cool down. As the strip cools, it straightens, moving the fuel gauge needle from 'full' toward 'empty.'

How to Solve the Problem of High Fuel Consumption?

High fuel consumption can be addressed by inspecting and repairing car components. Here are specific methods to solve high fuel consumption: Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. After cleaning, it is best to drive at high speed for a while, as this helps increase exhaust volume and allows stronger airflow to carry out larger carbon deposit particles. Check the oxygen sensor: As an internal control unit in the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. When the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust during driving, and the oxygen sensor should be replaced at this time. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.

Where is the thermostat located on the Besturn B30?

The thermostat of the Besturn B30 is located at the water inlet of the engine water pump. Introduction to the thermostat: It automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will severely affect the normal operation of the engine. For example, if the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine's warm-up time, resulting in the engine temperature being too low. Function of the thermostat: The role of the thermostat is to prevent the engine from becoming too cold. For instance, after the engine is operating normally, when driving at high speeds in winter, without a thermostat, the engine temperature might become too low. In this case, the engine needs to temporarily stop the water circulation to ensure the engine temperature does not drop excessively.
