The gear oil should be changed approximately every 40,000 kilometers. The specific replacement interval should be based on the manufacturer's user manual. The service life of vehicle gear oil is related to factors such as the vehicle model, oil quality, usage conditions, and driving habits. Gear oil, also known as transmission oil, can be divided into manual transmission oil and automatic transmission oil. Gear oil is primarily composed of petroleum lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents. It is an important lubricant used in various gear transmission devices to prevent gear surface wear, scuffing, and seizing, thereby extending their service life and improving power transmission efficiency.

How to Deal with Peeling Car Clear Coat?

Car paint peeling repair steps are: 1. Clean the car paint surface and ensure it is thoroughly dried; 2. Remove the peeling part of the car paint; 3. Simply repaint using the required painting method and materials. Additional information: 1. After the car has just been painted, it is best not to wash the car for at least 24 hours, preferably 48 hours, because the newly applied paint has not fully adhered during this time. Washing the car within this period will definitely damage the clear coat on the paint surface, thereby reducing the paint's adhesion capability. 2. Car paint peeling occurs because there was an issue with the ratio of clear coat to hardener during the painting process, preventing the clear coat from adhering properly.

What is the working principle of the intake air temperature sensor?

The working principle of the intake air temperature sensor is: During operation, the intake air temperature sensor contains a thermistor with a negative temperature coefficient. This thermistor detects temperature changes and adjusts the resistance value, thereby altering the circuit voltage. Below is a detailed introduction to the intake air temperature sensor: 1. Principle: The intake air temperature sensor is a negative temperature coefficient thermistor. When the temperature rises, the resistance value decreases, and when the temperature drops, the resistance value increases. The voltage in the vehicle's circuit changes with the variation in resistance, generating different voltage signals, which enables the automatic operation of the vehicle's control system. 2. Function: The intake air temperature sensor detects the intake air temperature of the vehicle's engine and converts it into a voltage signal, which is then input to the ECU for use as a signal for fuel injection correction.

What does ETC expiration mean?

ETC expiration may be caused by self-removal or relocation of the OBU device, ETC running out of power, or the ETC electronic tag falling off or becoming loose, all of which can render the ETC unusable. If a newly issued ETC shows an expired card, this is normal and does not affect activation. You can press the ETC anti-tamper switch on the back, and the red light will briefly turn on. The OLED display will show "ETC tag invalid," indicating that the ETC electronic tag is not activated, which is normal. ETC activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on." If inserting and removing twice without the electronic tag attached displays "Tag invalid," this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click "Connect device" and wait patiently for the "Connection successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.

Which Side is the Brake and Which Side is the Accelerator in an Automatic Transmission?

In automatic transmission models, the left side is the brake, and the right side is the accelerator. Automatic transmission vehicles do not require the driver to shift gears manually, so there is no clutch pedal—only the brake and accelerator pedals. When driving an automatic car, only the right foot is needed. It is extremely dangerous to place the left foot on the brake pedal while driving. Here are some precautions for driving an automatic transmission car: 1. Both the brake and accelerator are operated by the same foot, typically the right foot. This design is for safety reasons, as it enhances safety during emergencies when people may panic. 2. When pressing the brake or accelerator, the body needs support to maintain balance. The right foot operates the pedals while the left foot remains firmly on the floor to stabilize the body. If both feet were placed on the brake and accelerator, they would both be in a semi-suspended state without a stable point of contact, which could lead to unstable operation of the accelerator or brake.

Why does the car stall at idle?

Here are the reasons why the car stalls at idle: 1. Throttle blockage, carbon buildup, or abnormal opening; 2. Carbon buildup or blockage in the fuel injector; 3. Spark plug burning or damage; 4. Use of low-quality gasoline, leading to fuel pump blockage; 5. Insufficient combustion of the air-fuel mixture in the cylinder. Solutions for the car stalling at idle: 1. Regularly clean the throttle; 2. Regularly clean the fuel injector to prevent carbon buildup; 3. Replace the spark plugs; 4. Use gasoline from reputable gas stations. Additional information: Car stalling at idle refers to the engine running well from low to high speeds after starting, but stalling immediately after releasing the accelerator pedal or first running unsteadily and then stalling.

What Causes the Clutch of Baojun 730 to Lose Pressure?

Dirty transmission oil, clutch spring failure, and spring aging are the reasons why the Baojun 730 clutch loses pressure. Dirty transmission oil: If the clutch oil is dirty and contains impurities, it can cause severe wear on the internal piston of the clutch master cylinder and may even clog the oil holes, leading to a loss of clutch pressure and poor clutch return. During driving, the oil passage may become blocked by air, and the working cylinder in the transmission may wear out, resulting in the clutch failing to return properly. Generally, the transmission oil should be replaced after 6 years or 60,000 kilometers of driving. Clutch spring failure: If the clutch return spring ages and loses its elasticity, it may cause the clutch pedal to not return properly. After purchasing the car, the clutch is carefully calibrated. However, poor driving habits or subpar workmanship can lead to loosening or deformation of the clutch pedal spring. If this is the case, simply replacing the spring with a new one will resolve the issue. Spring aging: In manual transmission cars, the clutch is frequently pressed during driving. Over time, this continuous use can cause the clutch spring to wear out and age, rendering it ineffective. In such cases, replacing the spring at a repair shop will restore functionality.
