What Are the Types of Lubricating Oil?

What is the reason why an automatic transmission car sometimes does not move when shifted into gear?

Here is a detailed introduction to the specific reasons why an automatic transmission car does not move when shifted into gear: 1. Functional obstacle: Generally, the inspection starts from the driving wheels through the rear axle to the drive shaft, then to the transmission, and finally to the clutch. If the drive shaft rotates but the car does not move forward, the fault lies in the rear axle. Lift the rear axle and rotate one rear wheel. If the other rear wheel rotates in the opposite direction but the drive shaft does not rotate, it indicates that all the rivets of the driven bevel gear are broken; if the other rear wheel does not rotate either, the half shaft should be disassembled and inspected for breakage. 2. Transmission fault: If the car is shifted into a certain gear to start but the drive shaft does not rotate, it indicates a fault in the transmission. Remove the transmission cover and inspect whether the transmission shift fork is broken and whether the guide block fixing screws are loose. If the above inspections are normal, perform a gear-shifting test. If the second shaft does not rotate when a certain gear is engaged, it means the half-round key of that gear is broken.

Where is the brake light switch on the Nissan Qashqai?

The brake light switch on the Nissan Qashqai is located inside the brake pedal. Additional information: 1. Installation location: Brake lights are generally installed at the rear of the vehicle, with the main body color being red to enhance the penetration of the light source. This ensures that vehicles behind can easily detect when the vehicle in front is braking, even in low visibility conditions, thereby helping to prevent rear-end collisions. 2. Body color options: The Qashqai offers six color choices. Compared to Ivory White, Moonlight Silver, Feili Gray, and Jasper Black, the Fashion Gold and Xuan Ya Red options are undoubtedly more vibrant. On the road, the Fashion Gold variant is the most commonly seen. 3. Tires: The Qashqai mainly features two tire and wheel rim combinations. The 2.0XL or MT/CVT models come with 16-inch hollow five-spoke rims paired with Hankook tires, while the mid-to-high-end 2.0XV Thunder/Tiger/Dragon models are equipped with 17-inch five-spoke rims and Bridgestone tires.

What Causes High Engine RPM in Winter?

High engine RPM in winter is caused by reasons such as not warming up the car before driving, severe carbon buildup in the engine, or faults in the engine's intake system or pipelines. Not warming up the car before driving: It is necessary to warm up the car before driving. Generally, warming up for about half a minute is sufficient; prolonged warming up is not required. Then, gradually accelerate to avoid damaging the car's engine. Severe carbon buildup in the engine: Dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. In this case, the carbon deposits should be cleaned promptly. Faults in the engine's intake system or pipelines: It is recommended to inspect the intake system or pipelines; check the throttle body (including sensors); inspect the coolant temperature sensor; examine the fuel injectors and ignition system; and check the accelerator pedal and its sensor.

How Often Should the Coolant Be Replaced?

Coolant should generally be replaced every 2 years or 40,000 kilometers. Below are detailed explanations about coolant (antifreeze): 1. Definition: The full name of coolant is antifreeze coolant, meaning it is a cooling liquid with antifreeze properties. Coolant prevents the liquid from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. 2. Functions: Engine coolant has characteristics such as antifreeze, anti-boiling, anti-corrosion, anti-scale, and being foam-free. It is not affected by seasons or regions. 3. Quality Standards: The primary measure of coolant quality is its antifreeze performance. Water freezes at 0°C, while standard coolant can typically reach -40°C. High-quality coolant should achieve around -60°C, which is an important indicator of its quality. Another factor is the boiling point of the coolant. Water boils at 100°C, whereas coolant should reach at least 108°C. In other words, the lower the freezing point and the higher the boiling point, the greater the temperature range, indicating better coolant quality.

How Often Should the Spark Plugs on a Toyota Corolla Be Replaced?

Toyota Corolla uses Denso iridium platinum spark plugs, model SC20HR11, with a replacement interval of 60,000 to 80,000 kilometers. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the owner's manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plugs are crucial components of a gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Main types of spark plugs include: standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs.

How Long is the Validity Period of the Driving Skill Test Certificate?

The validity period of the driving skill test certificate is three years. Applicants must complete the subject two and subject three tests within the validity period. If the tests are not completed within the validity period, the passed subjects will be invalidated. Article 32 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" stipulates that for students who apply for a motor vehicle driving license for the first time or apply to add a permitted driving model, the vehicle management office shall issue a driving skill test certificate within one day after passing the subject one test. If the driving skill test certificate is lost, you can go to the driving school to reapply. If the written test admission ticket is lost, it can only be reprinted. The reprinting methods are as follows: Previously saved backups, including scanned copies, webpage screenshots, saved webpage files, photos, etc., are all valid as long as the information is clear; log in to the local personnel examination website again, enter the printing page, and reprint; if none of the above methods can solve the problem, please call the examination organizing unit, usually the local personnel bureau, to inquire about the relevant situation and arrange for a separate print.
