When replacing the belt, it is necessary to replace the tensioner pulley. Here is an extended introduction about the tensioner pulley: 1. Structure: The tensioner pulley mainly consists of a fixed housing, tension arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the different tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. 2. Function: The tensioner pulley is a wearable part in automotive components. Over time, belts tend to stretch. Some tensioner pulleys can automatically adjust the belt tension. Additionally, with a tensioner pulley, the belt operates more smoothly, reduces noise, and prevents slipping. The function of the tensioner pulley also includes adjusting the tightness of the timing belt.

What is the fuel consumption of the Pajero V93?

The official fuel consumption of the Mitsubishi Pajero as per the Ministry of Industry and Information Technology is 12.4L/100km. Here are the relevant details: 1. In actual driving conditions, road conditions and engine operating conditions are very complex, so the official fuel consumption will be lower than the real average fuel consumption of car owners. 2. The engine of the Mitsubishi Pajero is derived from the 6G71 engine by enlarging the cylinder, so its stroke is as short as that of the 6G71 engine, only 76mm. Although it is a 6-cylinder engine, to obtain greater power output, it is necessary to increase the engine speed, and higher RPM is required to gain torque and power, which is not ideal for off-road vehicles. 3. Fortunately, Mitsubishi has made a series of modifications to the later Pajero models, reducing the compression ratio, which greatly improved the overall durability of the engine, and optimized the torque curve, allowing for a larger torque of 225Nm at 2000-5600rpm.

What Are the Reasons for Poor Cooling Effect of Car Air Conditioning?

Here are the reasons for the poor cooling effect of car air conditioning: 1. Clogged air filter: A clogged air filter results in reduced airflow. Although the air is cool enough, insufficient airflow makes it feel like the cooling is inadequate. Replacing the air filter can solve this issue. 2. Excessive dust in the evaporator box: It is generally recommended to replace the air filter twice a year—once in winter and once in summer. The air conditioning system should be cleaned once every one or two years, depending on usage frequency, preferably in summer. There is no need to clean the heating system in winter. 3. Dirty condenser: The condenser, located in front of the radiator, is used to dissipate heat from the refrigerant. It can often get clogged with debris such as lint, leading to poor heat dissipation and reduced cooling performance. 4. Insufficient refrigerant: If the refrigerant level in the air conditioning system is low, the pressure decreases, reducing the amount of heat removed and resulting in inadequate cooling. 5. Faulty components in the air conditioning system: Damaged compressor, expansion valve, etc., require inspection and repair at a 4S shop.

What to Do When BMW RDC Tire Pressure Monitoring Fails?

The sensor or module may be malfunctioning, it is recommended to have it checked at a 4S shop; If the sensor or module is not malfunctioning and the program has not been flashed, then resetting it should be fine; Reset before going out, the car needs to be driven for a while, it will automatically check. BMW's tire pressure monitoring system RDC consists of a DSC module with RDC control function and 4 wheel sensors. In many European and American countries, it is a legal requirement for vehicles to be equipped with this system. When the vehicle speed reaches 20-30km/h, the RDC starts working, with the wheel sensors having a test cycle of 3 seconds, sending data to the DSC module every 30 seconds. If a loss of tire pressure is detected, the test and data transmission cycle is shortened to 1 second. The effective working temperature of the wheel sensors is between -40℃ and +125℃. The lithium-ion battery of the wheel sensors is designed for a service life of 10 years.

Can the battery still be used after adding water when it runs out?

The battery cannot be used after adding water when it runs out. Because only distilled water can be added to the battery, otherwise it will affect the battery's function. Here are some related introductions about car battery maintenance: 1. Turn off all lights before turning off the engine: Some older models do not support the function of automatically cutting off the power after turning off the engine, so the car lights and interior reading lights need to be turned off manually before turning off the engine. If you need to find something in the car or need lighting, you can use your mobile phone or flashlight for lighting, so as not to forget to turn off the reading light and cause the battery to lose power. 2. Turn off the air conditioning and audio before turning off the engine: The air conditioning system involves the compressor and blower, and the audio is also a high-power electrical device. If they are not turned off before turning off the engine, they will automatically start the next time the car is started, which will cause a heavy burden on the battery and damage it. Especially for some music enthusiasts who have modified the car audio, the usual power consumption increases, and the impact on the battery when starting will be greater.
