Is it safe to drive with the sunroof open on the highway?

It is not safe to drive with the sunroof open on the highway. Driving with windows open on the highway poses significant safety risks. Here are the reasons why it is not recommended to open windows while driving on the highway: 1. Increased fuel consumption: At high speeds, the car's streamlined design effectively reduces wind resistance. However, opening the windows disrupts the airtightness, leading to increased air resistance and consequently higher fuel consumption. 2. Increased noise: Opening the windows at high speeds significantly increases wind noise, reducing comfort. 3. Interior gets dirty: Driving with windows open on the highway naturally makes the interior/roof lining more susceptible to dust accumulation. 4. Increased risk of accidents: The typical speed on highways is around 120 km/h, and many drivers store luggage or tools in the trunk. Strong winds from open windows can cause imbalance, leading to traffic accidents.

Do Sedans Have a Radiator and Need Water Refill?

Sedans do have a radiator and require water refill. Generally, when a car is low on coolant, water is added as a temporary solution. Precautions for adding water to a new car are as follows: 1. Do not use ordinary water as a substitute for coolant; 2. Avoid mixing coolants of different colors and specifications; 3. When using coolants from different brands, try to drain the original coolant from the cooling system thoroughly; 4. Regardless of high or low temperatures, coolant should be used for the efficiency and longevity of the cooling system; 5. Tap water contains many substances that can easily cause rust and scale buildup. Coolant, on the other hand, can lower temperatures, regulate heat, and is less prone to deterioration and chemical reactions.

Why is the temperature gauge normal when the thermostat is broken?

Thermostat damage temperature gauge normal reason is thermostat protection water temperature does not drop: The following is the relevant content introduction: 1. The working principle of the thermostat: The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, changes the circulation range of the water, and adjusts the heat dissipation capacity of the cooler to ensure that the engine works within a suitable temperature range. The thermostat must maintain good technical condition, otherwise it will seriously affect the normal operation of the engine. 2. The role of the thermostat: to prevent the engine from being too cold. After the engine is working normally, when driving at high speed in winter, if there is no thermostat, the engine temperature may be too low. The engine needs to temporarily terminate the water circulation to ensure that the engine temperature is not too low.

Is the Jetour X70 equipped with a dry dual-clutch transmission?

Jetour X70 is equipped with a dry dual-clutch transmission. Working principle of dry dual-clutch transmission: It uses two clutches to work alternately. The difference between dry and wet dual-clutch transmissions lies in the medium connecting the driving plate and the driven plate. Wet dual-clutch transmissions mainly rely on oil, while dry dual-clutch transmissions primarily depend on air. Basic structure of dry dual-clutch transmission: The friction plates of dry dual-clutch transmissions do not have sealed oil grooves and require air cooling for heat dissipation. Advantages and disadvantages of dry dual-clutch transmission: The advantage of dry dual-clutch transmission is fast gear shifting, while the disadvantage is its relatively low torque capacity.
