What Constitutes Abnormal Wear on Car Tires?

What are the symptoms of a faulty coolant temperature sensor?

The symptoms of a faulty coolant temperature sensor are: 1. The temperature gauge needle does not move and points to the highest position; 2. Difficulty starting the engine when cold, displaying a warm engine temperature signal, causing the ECU to receive no signal for a rich air-fuel mixture and only providing a lean mixture; 3. Increased fuel consumption and unstable idle; 4. Difficulty accelerating, with the engine speed not increasing even when the throttle is fully pressed. A sensor is an electronic component in the car's circuit. If it is damaged, there is little room for repair, and it must be replaced. If you want to test the sensor, a simple method is to place the coolant temperature sensor in a heating cup (be careful not to submerge the connector part) and use the "resistance range" of a multimeter to measure it. As the temperature rises, the resistance should decrease. If there is no change, it indicates that the sensor is faulty.

Can 92 and 95 Octane Gasoline Be Mixed?

92 octane and 95 octane gasoline can be mixed, as these two types of gasoline only differ in their anti-knock performance. This means lower-octane gasoline can be mixed with higher-octane gasoline for use. However, vehicles that consistently use 95 octane gasoline should not mix in 92 octane gasoline—in other words, higher-octane gasoline should not be mixed with lower-octane gasoline, as this may result in insufficient vehicle power. The higher the octane rating, the greater the isooctane value, and the higher the proportion of isooctane, the better the gasoline's anti-knock performance, which significantly helps curb carbon deposit formation after combustion. When gasoline is compressed in the engine combustion chamber to perform work, if its anti-knock performance is poor, it may ignite prematurely, causing knocking. Gasoline with good anti-knock performance prevents this from happening. The higher the engine's compression ratio, the higher the requirement for the gasoline's anti-knock performance.

What to Do If the Driver's License Expires Without Renewal?

Penalties for driving with an expired license: Driving during the expiration period is prohibited and may be treated as driving without a license. If the license has been expired for less than one year, the driver can renew it at any time, but driving during this period may result in a fine of 200 yuan. If the license has been expired for more than one year without renewal, the traffic management department will revoke it. If the expiration period is less than three years, the driver must retake and pass the subject one exam to restore driving privileges. Driving during this period may result in a fine ranging from 200 to 2,000 yuan. If the license has been expired for more than three years, it will be permanently revoked. To drive again, the driver must retake the entire license exam. Otherwise, driving will be treated as driving without a license, punishable by a fine of 2,000 yuan and up to 15 days of administrative detention. Renewal process: The driver must submit the required materials to the vehicle management office where the license was originally issued. The office will process the renewal within one working day upon approval.

Within what distance of 50 meters is it prohibited for motor vehicles to park?

Motor vehicles are prohibited from parking at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. Parking in these areas not only endangers the driver's property and personal safety but also poses risks to others' property and safety. Below are the regulations for temporary parking of motor vehicles on the road: 1. Parking is prohibited in sections with no-parking signs or markings, sections with separation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, crosswalks, and construction zones. 2. Parking is prohibited at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. 3. Parking is prohibited in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (including within 30 meters of these locations), except when using these facilities. 4. Doors must not be opened or passengers allowed to board or alight before the vehicle comes to a complete stop, and opening doors must not obstruct other vehicles or pedestrians. 5. Roadside parking must be close to the right side of the road, and the driver must not leave the vehicle. The vehicle must depart immediately after passengers board or alight or after loading or unloading goods. 6. City buses are not allowed to stop to pick up or drop off passengers outside designated bus stops.

Will I Forget If There's Too Long a Gap Between Subject Two and Subject Three?

There might be some forgetting if the gap between Subject Two and Subject Three is too long. However, it's not a big issue. The main concern is unfamiliarity with things like the accelerator and brake, which can be refreshed before officially starting the lessons. The content of Subject Two and Subject Three is essentially different, so forgetting doesn't have much impact. Additional Information: Below is a related introduction to the content of the driver's license examination subjects: 1. Subject One: Driving theory foundation, road safety laws and regulations, etc. 2. Subject Two: Five mandatory tests including reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. 3. Subject Three: 16 test items including vehicle preparation, starting, driving straight, etc. 4. Subject Four: Safe and civilized driving test.
