What Causes a Manual Transmission Car to Fail to Shift Gears After Starting?

How Long Does It Take to Repair a Car at a 4S Shop?

Depending on the damaged parts and the extent of the damage, the repair time will vary. If easily worn parts like tires or lights are damaged, or if there are minor scratches on the front or rear bumper, the repair usually takes 1-2 hours. However, if core components like the engine or transmission have serious issues, the repair time can range from several days to several weeks. Factors affecting repair time: Generally, surface damage to a car is easy to repair, but internal damage requires disassembling the vehicle, which is more troublesome and time-consuming. The more severe the damage, the more difficult and time-consuming the repair will be. If spare parts are readily available, the repair will be faster. If parts need to be ordered, the waiting time will increase, prolonging the repair period. The skill level of the technician also affects the speed of the repair. Notes on car repair: You can choose to repair your car at a 4S shop or an external repair shop, each with its pros and cons. 4S shops guarantee repair quality and usually offer a warranty period after repairs, but they are more expensive and slower. Repair shops are cheaper and faster, but the quality can be inconsistent.

Can 5W20 engine oil be used in summer?

5W20 engine oil cannot be used in summer. The number after W in 5W20 engine oil is 20, indicating a relatively poor viscosity grade. During summer, high temperatures combined with continuous engine operation lead to increased internal temperatures. Engine oil with inadequate viscosity may cause engine damage. 5W20 engine oil is a multi-grade oil. W stands for Winter, the number before W represents the low-temperature resistance index, and the number after W indicates the viscosity index of the oil. 5W means the oil can withstand low temperatures as low as -30 degrees Celsius, meaning this type of oil can still perform its function at -30 degrees Celsius. If the number before W is 10W, it indicates the oil can tolerate low temperatures down to -20 degrees Celsius. In automotive engine oils, the summer oil grades are: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the maximum applicable temperature. The winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the minimum applicable temperature.

What type of fuel should a motorcycle use?

Generally, motorcycles use 92-octane gasoline, but 95-octane gasoline can also be used. Below is relevant information about gasoline: 1. Octane Rating: Different grades of gasoline have different octane ratings. The higher the grade, the higher the octane rating. Gasoline with a higher octane rating also has better anti-knock properties. Motorcycle engines with relatively high compression ratios generally require the use of 95-octane gasoline to prevent engine knocking. 2. Knocking Phenomenon: Knocking is an abnormal combustion phenomenon in the engine. A four-stroke gasoline engine has a compression stroke. After the compression stroke ends, the spark plug should ignite the combustible mixture, allowing it to burn and generate power to push the piston downward. Knocking occurs when the combustible mixture ignites on its own before the spark plug fires. At this point, the piston is moving upward, and the burning mixture pushes it downward, which can affect the engine's power output and even damage the engine. Severe knocking can even cause piston cracking or connecting rod deformation.

Can a car charge the battery while idling in place?

When a car is idling in place after starting, it can charge the battery. However, the electricity charged in this way is commonly referred to as "floating charge," which exists for a short period and will dissipate if the car is parked for a slightly longer time. If the battery charging indicator on the dashboard is not lit, it means the car is charging. If it stays lit, it indicates a charging fault, and the car should be taken to a repair shop for inspection. Below is an introduction to charging while idling: Operating principle of charging: Essentially, the engine drives the alternator (generator) to generate electricity, which is then rectified and stabilized to provide a certain voltage to the battery. Most of the time, this voltage is slightly higher than the battery voltage (e.g., 14V, while a normal battery is typically 12V), achieving constant voltage charging. Introduction to idling in place: Idling in place refers to a condition where the engine is running but the car is not moving, with the gear in neutral. This is often described as "working without output," consuming fuel without moving the car. The charging duration can also be affected by other factors, such as whether high-power devices are being used in the car, whether the air conditioning is on, or whether external USB power is being supplied. These factors can all increase the charging time.

Are the tires at 4S stores all original factory tires?

4S stores use original factory tires because all replacement parts at 4S stores need to be covered by warranty. Using original factory tires can to some extent enhance structural and performance guarantees. The parts used by 4S stores are directly supplied by manufacturers. If you go to an authorized 4S store for replacement, the tires will be identical to the original ones with no difference. During replacement, you can check the part number to verify if it's an original factory part. Advantages of using original factory tires: High compatibility with the vehicle: Original tires (parts) designed specifically for each vehicle model ensure the same technical condition and quality as new car parts, maintaining the vehicle's premium performance. Quality assurance: Every original tire (part) used by 4S stores is quality-certified by the automaker, ensuring reliable operation. Long warranty period: For genuine parts replaced at the customer's expense, replaced free of charge, or replaced free of charge due to recall repairs outside the vehicle warranty period (excluding vulnerable parts specified in the home vehicle three-proof certificate), the quality warranty period is 1 year or 20,000 kilometers. Whichever comes first between time and mileage applies.

What are the precautions for buying a car in full payment at a 4S store?

Precautions for buying a car in full payment at a 4S store include determining the ex-factory price, being cautious with free gifts, verifying the chassis number upon pickup, and inspecting the engine compartment. Determine the ex-factory price: When buying a car in full payment, consumers need to understand the ex-factory price. Generally, 4S stores do not force buyers to purchase insurance or other fees when paying in full, so consumers should negotiate based on the ex-factory price. Be cautious with free gifts: During price negotiations, 4S store salespeople may offer free gifts, which are usually inexpensive. If possible, consumers can request the value of the gifts to be deducted from the ex-factory price, making a price reduction more beneficial. Verify the chassis number upon pickup: When picking up the car, ensure the chassis number matches the code on the certificate of conformity. Check the production date of the car; a reasonable range is 3-6 months. Cars older than one year are not recommended for purchase. Inspect the engine compartment: Open the hood to check if the engine compartment is clean. Start the car for a few minutes, pull out the oil dipstick to check if the oil level and condition are normal, and inspect for any oil stains under the engine compartment.
