What are the items included in a car's first maintenance service?

New car first maintenance usually involves simple tasks like changing the engine oil and oil filter, followed by a comprehensive vehicle inspection. The details are as follows: 1. Tightening nuts: During the first maintenance, all nuts on various parts of the new car will be inspected. Considering the break-in period of a new car, some screws may not be particularly tight. During the first maintenance, all screws will be tightened to the specified torque. 2. Chassis inspection: The car will be lifted to check the chassis for any scratches, underbody impacts, corrosion, or oil leaks. 3. Tire inspection: Mainly to check if tire wear is consistent. If one tire shows significantly more wear, it may indicate potential wheel misalignment. Additionally, tire pressure will be checked and adjusted as needed. 4. Computer system check: A computer system diagnosis will be performed to comprehensively detect any car issues, after which technicians will conduct repairs based on the identified problems.

How long should you avoid rain after replacing the windshield?

After replacing the windshield, avoid rain for three days. The method for replacing the windshield is as follows: 1. First, use a flat-head screwdriver to slowly remove the black protective strips around the windshield, then remove the wipers and the protective cover under the windshield; 2. Thread a steel wire through the sealant under the windshield, with one person inside the car and one outside, pulling back and forth to slowly separate the sealant until all the sealant around the entire windshield is loosened; 3. Use a small blade to slowly scrape off any remaining black sealant on the car, then use sandpaper for final cleaning until the metal frame is exposed. Wipe the dust off the newly purchased windshield with a cloth; 4. Apply polyurethane sealant to the frame of the car windshield in a triangular or diamond shape, making it as thick as possible to ensure a tight bond with the glass; 5. When installing the windshield, note that there are two small brackets on the car to support the windshield. Make sure the windshield rests on these small supports. Slowly press it into place, then apply another layer of polyurethane sealant around the windshield to attach the black protective strips; 6. After installation, reattach the wipers and the lower protective panel, and use transparent tape to secure the windshield to the roof. It's best not to drive immediately after completion; instead, let the car sit for two or three days to allow the sealant to fully cure.

Why Has the Steering Wheel Become Heavier Than Before?

There are several reasons why the steering wheel has become heavier than before: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which helps transmit steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering wheel will feel heavy and stiff. 2. Low tire pressure: Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel. This is not conducive to driving safety. 3. Toe-in: Toe-in can also affect the car's steering. The concept of toe-in is quite complex, but simply put, it helps the steering wheels automatically return to the correct position, ensuring the car can drive straight stably. If there is an issue with this aspect, it can also cause the steering wheel to feel heavy. 4. Steering gear or power steering pump failure: The steering gear and power steering pump are also critical components that affect the car's steering. Any malfunction in these two important parts can lead to steering difficulties. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked.
