Is It Normal for a Car Sunroof to Leak?

It is not normal for a car sunroof to leak. Reasons for a car sunroof leaking: 1. The sunroof drainage outlet is blocked by debris, preventing rainwater from draining and gradually seeping into the car; 2. The sunroof sealing strip is damaged, leading to poor edge sealing; 3. There are gaps in the sunroof frame. A car sunroof is installed on the roof and can effectively circulate air inside the car, increase the intake of fresh air, and also provide a broader view and meet the needs of mobile photography and videography. Maintenance of a car sunroof: 1. Fully open the sunroof and use a clean, soft cloth to wipe off dust on the sliding rails, then apply a lubricant that does not easily attract dust to lubricate the sliding rail parts and transmission pipes of the sunroof; 2. Before long-term parking, thoroughly clean the sunroof with talcum powder to prevent chemical changes in the rubber strips due to prolonged exposure to air; 3. Check the rubber strips and grooves of the sunroof for dust, leaves, small branches, or other debris; 4. When using a high-pressure water gun to wash the car, avoid directing the water spray directly at the sealing rings around the sunroof.

How to Measure Car Engine Oil Most Accurately?

Correct method to check the oil dipstick: First, park the vehicle on a level surface because the oil pan is generally irregular in shape, and the markings on the dipstick are based on the upper and lower limits of the oil level in the pan when the vehicle is level. If the vehicle is tilted, the oil in the pan will flow to the lowest point while the dipstick position remains unchanged, resulting in an inaccurate oil level measurement. Steps to check the oil dipstick: 1. Locate the handle: Prepare a tissue before inspection, then find the handle of the oil dipstick in the engine compartment. 2. Wipe clean: Pull out the oil dipstick and use the tissue to thoroughly wipe off the oil clinging to the dipstick head. This will allow you to clearly see the markings on the dipstick. 3. Reinsert the cleaned dipstick: Ensure the entire dipstick is fully inserted, then pull it out again. Note: When removing the dipstick, pay attention to the way you hold it—it can be vertical, tilted, or horizontal, but never upside down, as this may cause the oil on the dipstick to flow backward, affecting the accuracy of the oil level reading. 4. Check the position: Observe the oil clinging to the dipstick to determine the oil level. If the oil level is below the MIN mark or above the MAX mark, it indicates that the engine oil needs to be topped up or there is too much oil.

How often should the coolant be replaced in a Cadillac XTS?

Cadillac XTS coolant generally needs to be replaced every two years or approximately 40,000 kilometers. Before completely replacing the coolant, a thorough inspection should be conducted to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way water pipe. The five-way pipe is named for its five connecting interfaces that link various parts. Coolant flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of coolant in this section, the water pipe should be replaced or the interface should be re-secured as needed. Drain the old coolant and then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir may have a faint pink tint. Continue adding clean water until the water coming out is clear. Note: Do not forget to remove the heater hose and drain the water from the heater core. About an hour after draining, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, add another container of coolant to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Top up the coolant again until it reaches the "MAXT" mark on the reservoir.

Where Are Lexus Factories Located?

Lexus has five main factories, three of which are located in Japan: the Kyushu Plant in Fukuoka, Japan; the Tahara Plant in Aichi Prefecture; and the Motomachi Plant in Aichi Prefecture. The other two are the Ontario Plant in Canada and the Kentucky Plant in the United States. Here are some related details: 1. Lexus Vehicles Sold in China: 90% of the Lexus vehicles sold in China are produced at the Kyushu Plant in Fukuoka, Japan. There are only two Toyota-certified factories worldwide, and the Kyushu Plant is one of them. 2. Lexus Production Time: At the Kyushu Plant, it takes a total of 19 hours for a Lexus vehicle to go from initial stamping to final assembly and inspection of nearly 30,000 parts. The painting process alone takes about 10 hours, while assembly and inspection take approximately 5 hours. 3. All Lexus Models Are Produced to Grade A Standards: Toyota internally classifies its production standards into four grades: A, B, C, and D, with D being the lowest. Vehicles produced to D-grade standards include all of Toyota's compact cars and some larger models supplied to the U.S. market, such as the Yaris series, Vios series, and Highlander. C-grade standards apply to mainstream Toyota models like the Camry and Avalon. The Crown is produced to B-grade standards, while the Crown Majesta and all Lexus models are produced to A-grade standards.

What is the 2020 Vehicle Inspection Policy?

2020 introduced new regulations for vehicle inspections, as follows: 1. Non-operational passenger cars: Non-operational passenger cars (including non-operational sedans, small and micro passenger vehicles) are subject to a 6-year exemption policy, meaning new vehicles within 6 years are exempt from on-site inspections. However, note that every 2 years, an inspection label must be applied for from the traffic management authorities; otherwise, it will be considered as failing the inspection. SUVs and MPVs with 7 seats or more do not qualify for the 6-year exemption policy. 2. Vehicles registered for over 6 years: Vehicles registered for over 6 years are subject to an annual inspection policy; vehicles registered for over 15 years are subject to a semi-annual inspection policy. 3. Operational passenger vehicles: Operational passenger vehicles registered within 5 years are inspected annually; those registered for over 5 years are inspected every 6 months. 4. Trucks: Trucks and medium/large non-operational passenger vehicles are inspected annually for the first 10 years; those over 10 years old are inspected every 6 months. 5. Inspection date: The inspection date is the month of vehicle registration, and inspections can be conducted up to 3 months in advance. For example, a vehicle registered in May can be inspected in March, April, or May. 6. Vehicles eligible for annual exemption: Vehicles eligible for annual exemption can complete the inspection online without visiting the vehicle management office. After verifying compulsory traffic insurance through the internet traffic safety service platform, the exemption label can be directly applied for online, eliminating the need for in-person visits or driving license endorsements, with the label delivered by mail.

Daily Driving Tips for Manual Transmission Cars

Manual transmission driving tips are as follows: 1. Sitting Posture: Place your right foot lightly on the brake pedal with the leg slightly bent to ensure sufficient force can be applied when needed. 2. Starting the Car: When starting a manual transmission car, depress the clutch pedal fully with your left foot, engage first gear, place your right foot lightly on the accelerator, slowly release the clutch while simultaneously releasing the handbrake and gently pressing the accelerator. After slightly lifting the left foot off the clutch pedal, immediately press the accelerator to achieve a smooth start. 3. Gear Shifting Timing: Generally, when driving in the city, the engine speed should be kept below 2000 RPM to balance good power performance with fuel efficiency. Experienced drivers can determine the optimal gear shifting moment by listening to the engine sound and feeling its vibrations. 4. Stopping at Traffic Lights: When approaching a traffic light, make an early judgment. If the light is about 200-300 meters away and the green light starts blinking, shift to neutral and coast to the intersection to wait for the red light. This saves fuel and is gentler on the brakes. 5. Downhill Techniques: When descending a long and steep slope, avoid coasting in neutral as it disables the engine braking function. In case of sudden situations, relying solely on brakes may not provide quick deceleration and could even lead to brake failure. 6. Avoid Prolonged Half-Clutch State: Some drivers habitually keep their left foot on the clutch while driving, thinking it offers better control. However, this practice significantly damages the clutch plate, especially during high-speed driving where prolonged half-clutch states can cause rapid wear. Additionally, starting in second gear can also lead to premature clutch damage.
