The tensioner pulley should be replaced as soon as possible if it makes noise. Here is some information about the tensioner pulley: 1. The tensioner pulley mainly consists of a fixed housing, tensioning arm, pulley body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. 2. The tensioner pulley is a wear-prone component in automotive parts. Over time, the belt may stretch, and some tensioner pulleys can automatically adjust the belt tension. Additionally, the tensioner pulley makes the belt run more smoothly, reduces noise, and prevents slippage. 3. The function of the tensioner pulley is to adjust the tightness of the timing belt. It is generally replaced together with the timing belt to avoid future issues. Other parts do not need to be replaced as long as regular maintenance is performed.

What does the yellow exclamation mark symbol on the fuel gauge mean?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these four situations: General Malfunction: An exclamation mark inside a triangle indicates a malfunction in the car's general performance or components and functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission failure warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside parentheses represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Failure: A yellow bulb with an exclamation mark is the lighting system failure indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. There is also a red exclamation mark inside a circle with parentheses, which represents a brake system warning. This could indicate a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.

Where is the air filter element of the BAIC EU?

The BAIC EU does not have an air filter element. This is a pure electric vehicle, which does not have an engine and thus no intake system. According to the maintenance manual, the car's air filter element is generally replaced every 10,000 to 20,000 kilometers or during every other maintenance session. However, it is recommended to clean the air filter element every 5,000 kilometers to reduce the buildup of throttle sludge. The function of the air filter element: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinders, and preventing airborne dust from being sucked into the engine, which would accelerate the wear of the piston group and cylinders. Air filter element: It is a type of filter, also known as an air filter cartridge, air cleaner, or air filter. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine needs to intake a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinders, accelerating the wear of the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly severe in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders. Dirty air cleaner: Using an excessively dirty air cleaner while driving can cause insufficient air intake into the engine, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must maintain a clean air cleaner. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air entering the cylinders to reduce early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must first pass through the fine filtration of the air cleaner. An excessively dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to have little dust and is lightly clogged, it can be cleaned with high-pressure air from the inside out and continue to be used. An excessively dirty air cleaner should be replaced promptly.

Why Does the Car Shake When Starting in Winter?

Winter car starting shake reasons are: 1. Low temperature: The exhaust pipe and oxygen sensor temperature is low, the vehicle ECU cannot obtain accurate data in time, causing errors in ignition and fuel-air mixture control, leading to weakened vehicle power output; 2. Car carbon deposits: Throttle carbon deposits have adhesion, preventing the fuel injection from reaching the required gasoline amount for combustion; 3. Spark plug aging: Different ignition gaps cause power deviations in each cylinder. Solutions for winter car starting shake are: 1. Let the car idle after cold start to allow the temperature to rise; 2. Clean the throttle and fuel injector; 3. Replace the spark plugs.

What to Do When Car Battery Voltage Is Too Low?

The solution for low car battery voltage is to use a portable charger to recharge it. The functions of the car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system during engine startup; 2. Supplying power to the car's electrical equipment when the engine is off or idling at low speed; 3. Acting as a voltage stabilizer for the entire vehicle's electrical system; 4. Storing excess electrical energy generated by the alternator. Precautions to prevent car battery discharge include: 1. Turn off all electrical equipment before parking; 2. Do not forget to turn off the car lights after shutting down the engine; 3. Avoid completely draining the battery; 4. Regularly check the battery voltage.
