Car fuel pumps should be replaced every 40,000 kilometers. The fuel pump is a crucial component of the electronic gasoline injection system in a car engine. The functions of the fuel pump are: 1. To provide hydraulic pressure for operating control valves and clutchers, and to supply a measured amount of gear oil to the transmission and differential case; 2. To deliver transmission oil to the cooler for circulation and heat dissipation. The maintenance methods for the fuel pump include: 1. Avoid using water-containing substances for vacuum extraction; 2. Use the fuel pump for vacuum extraction after removing most of the solvent in an oven; 3. Operate the vacuum pump in the correct sequence; 4. Add the specified grade of lubricating oil; 5. Ensure the fuel is clean, free from impurities and moisture.

How to Renew a Driver's License at Age 60?

For individuals aged 60 and above whose driver's licenses are expiring, it is necessary to follow the regulations to apply for a downgraded license renewal. Since April 1, 2016, new regulations stipulate that motor vehicle drivers aged 70 and above must undergo an annual physical examination. Within thirty days after the end of the scoring cycle, they must submit a medical certificate issued by a county-level or higher medical institution or a military medical institution at the regiment level or above. Details are as follows: Only drivers with a C1 or higher license need to undergo downgrading. Those with a license below C1 do not need to renew their license but should only pay attention to its validity period. Required documents include the original driver's license, original ID card, a copy of the ID card, and three passport-sized photos. Visit the local vehicle management office to apply for an over-age license renewal, which requires payment for the physical examination and the license processing fee. Then, proceed to the designated location for a physical examination. After completing the examination, return to the previous window with the medical form and submit all prepared materials. Follow the instructions of the vehicle management office staff. Normally, the process takes about 30 minutes to obtain the downgraded C1 license, completing the renewal process for a 60-year-old's downgraded driver's license.

Where is the spark plug located in a vehicle?

Spark plugs are located at the top of the vehicle's engine. Spark plugs utilize high-voltage discharge to break down the air between electrodes, generating an electric spark to ignite the combustible gas mixture in the combustion chamber, thereby maintaining the engine's operation. The quality of the spark plug directly affects the performance of the car's engine. The main types of spark plugs include: standard spark plugs, insulator-protruding spark plugs, electrode-type spark plugs, seat-type spark plugs, and pole-type spark plugs. Spark plugs require regular maintenance. If the car's engine speed is 1,000 RPM, the spark plug needs to perform 500 ignitions per minute. During maintenance, it is essential to first soften the carbon deposits with gasoline or kerosene, then clean them with a non-metallic brush, and finally dry them with compressed air.
