What is the reason why the Ford Focus automatic transmission cannot shift gears?

Is a car's water temperature of over 90 degrees normal?

A car's water temperature of over 90 degrees is not normal. The reasons for a car's water temperature being too high are as follows: 1. Coolant issues: Coolant leakage or insufficient coolant can cause the engine's water temperature to rise. In this case, the coolant level should be checked. If it is insufficient, first add coolant to the appropriate level, then check after a few days to see if the level has dropped significantly. 2. Radiator fan failure: If the radiator fan fails, when the vehicle is running at high speed, the heat generated cannot be transferred to the coolant in time, affecting heat dissipation and leading to an increase in the coolant's temperature, which can cause boiling and other issues. 3. Water pump failure: Water pump failures can include seized bearings or damaged impellers. Seized bearings are relatively rare, while damaged impellers are more common, such as impeller cracking or the impeller becoming loose from the pump shaft, which slows down the coolant circulation speed and can easily lead to engine overheating issues.

Does flooding a car affect it?

Flooding a car does have certain impacts on the vehicle. Additional details are as follows: 1. Engine cylinder block fracture: When the water level rises above the engine intake, water can directly enter the cylinders, forming a mixture of air and water. While gases are compressible, water is not. Consequently, when the crankshaft drives the connecting rod to compress towards the piston, the incompressible water causes the connecting rod to bend under hydraulic pressure. If the owner turns off the engine at this point and attempts to restart the car, the tremendous counterforce may cause the bent connecting rod to rub against the cylinder block, risking fracture of the engine's top section after deformation. 2. Transmission water immersion: Water can enter through transmission vent holes and other openings. The mixture of transmission fluid and water may require simple oil replacement and cleaning in minor cases. In severe instances, lack of lubrication accelerates mechanical wear and electrical damage, necessitating transmission overhaul. 3. Interior components: Untreated water ingress leads to mold growth, foul odors, deformation and damage. 4. Electrical components: Water causes short circuits in sensors, control units and other electronics. Flooded vehicle wiring may corrode over time, impairing normal operation.

What is the speed range for first, second, and third gears?

First gear is the starting speed, typically ranging from 0-5 km/h. Second gear corresponds to a speed range of 5-20 km/h. Third gear corresponds to a speed range of 20-40 km/h. Additional information is as follows: 1. Timing for upshifting: When the engine has sufficient power, it emits a dull "humming" sound. If after upshifting there is no power deficiency or shaking of the transmission mechanism, and the vehicle speed increases rapidly with smooth and natural driving, it indicates accurate timing for upshifting. 2. Timing for downshifting: When the vehicle speed and engine RPM continue to drop, and you feel the car losing power with engine compartment vibration, it's time to downshift one gear. Downshifting too early will cause noticeable jerking, wasting engine power, increasing fuel consumption, and affecting the lifespan of the engine and transmission. Downshifting too late will result in continued power deficiency even after downshifting, and further downshifting will still feel jerky. Misjudging the shifting timing can lead to such "irreversible" consequences, which will inevitably affect the driving experience.

At how many kilometers is the first maintenance for Volkswagen cars?

Volkswagen cars generally require their first maintenance at around 2,500 kilometers. The first maintenance refers to the initial service after the car has been driven, and its inspection items include: 1. Checking the car's coolant level; 2. Checking the brake and clutch fluid levels; 3. Checking the steering oil tank level and whether there are any oil leaks at the oil pipe connections; 4. Checking the battery fluid level and the windshield washer fluid level; 5. Checking the tension and aging condition of the belts for the generator, air conditioning, water pump, and power steering pump. Taking the 2021 Volkswagen Lavida Comfort Edition as an example, it is a compact 4-door, 5-seater sedan with body dimensions of: length 4670mm, width 1806mm, height 1474mm, and a wheelbase of 2688mm.

What are the new regulations for vehicle annual inspections within ten years?

The new regulations for vehicle annual inspections within ten years have adjusted the inspection cycle and the scope of exemption. The details are as follows: 1. Scope of exemption: The exemption scope for motor vehicles has been expanded from the original 6 years and within 6 seats to non-operational small and mini passenger vehicles with 7-9 seats. Starting from November 20, 2020, non-operational small and mini passenger vehicles under 6 years old with 7-9 seats can enjoy the exemption policy. 2. Inspection cycle: Exempted vehicles can skip on-site inspections for the first 6 years, only requiring formalities every two years, while inspections are required annually from 6-10 years. The new regulations indicate that the inspection cycle for private vehicles remains unchanged for the first 6 years, but for vehicles aged 6-10 years, the annual inspection is changed to biennial. This means exempted vehicles will have biennial inspections within 10 years, but only the 6th and 8th years require on-site inspections. 3. Vehicles not eligible for exemption: Vans; vehicles illegally modified and penalized by law; vehicles involved in traffic accidents causing casualties. Additionally, vehicles that have not been registered for over 4 years since the date of manufacture are not eligible for the 6-year exemption policy.

How many years is the first driver's license renewal?

The validity period of the first obtained driver's license is 6 years. Materials required for driver's license renewal upon expiration: Prepare 2 one-inch photos and a medical examination certificate. One photo should be affixed to the upper right corner of the medical examination form, and the other should be kept for the new license. Bring your ID card and driver's license to the license office, fill out the renewal application form, then submit the documents, medical examination certificate, and renewal application form to the staff, pay the processing fee, and wait to receive the new license. Before renewal, check if there are any unprocessed traffic violations. If there are, they must be handled first; otherwise, the renewal will not be processed. Plan the renewal time reasonably to avoid expiration. If the license expires and you are caught by traffic police, you will be fined but not penalized with points. It is best to have the photos and medical examination for renewal processed directly at the traffic police office, as self-prepared materials may not meet the requirements, leading to delays for retaking photos or redoing the medical examination. Renewal is usually completed on the spot, but in some large cities, it may take a few days, though it should not exceed 15 days. You will be notified to collect the new license. Within 15 days after the end of the scoring cycle, you must undergo a medical examination at a county-level or higher hospital and submit the results to the local traffic police branch for archiving.
