When the engine temperature is too high, even if the car is turned off and the key is removed, the cooling system will still automatically activate to cool down the engine system. Below is an introduction to engine maintenance: 1. Keep it clean: Keep the oil, water, air, and engine body clean. Impure fuel can affect the matching components, while impure coolant can hinder engine heat dissipation. 2. Keep it sufficient: Ensure sufficient oil, water, and air. Proper engine maintenance keeps the engine in good condition. 3. Quality fuel: Use reliable quality fuel and pay attention to the maintenance of the fuel system, which is especially important for fuel-injected engines. Regular inspection, addition, and replacement of engine oil are also part of engine maintenance. 4. Regular cleaning: Regularly clean the engine radiator to remove rust and scale, which is a method of engine maintenance. Also, regularly clean the fuel system to control carbon deposits and maintain the engine in optimal condition.

It's quite common for the car to still make noise after turning off the engine. I've seen this countless times during my decades of working in auto repair shops. The most frequent cause is the cooling fan continuing to run. When the engine runs for a long time and gets too hot, the electronic control system will keep the fan running after shutdown to prevent overheating damage to components. If the fan doesn't stop, it might indicate a faulty temperature sensor or a stuck relay - otherwise it's normal self-protection. Additionally, the exhaust system may produce some ticking sounds as metal parts contract during cooling. My advice: don't rush to drive off. Wait a few minutes after turning off the engine to listen for the noise source, and pop the hood to check if the fan is running. If the fan noise stops after a few minutes, no problem. But if it keeps running indefinitely, you'll need to check the electrical circuit or battery, otherwise it might drain the power and prevent the next startup. Remember this issue occurs more frequently during hot summer months - regular cleaning of the cooling system to prevent blockages can reduce trouble. Safety first - when discovering problems, have them properly handled by professionals for best results.

Why does the Geely Icon use a three-cylinder engine?

Geely Icon uses a three-cylinder engine mainly for the following reasons: Technological advancements: There have been breakthrough advancements in three-cylinder engine technology. When people mention three-cylinder engines, they can't help but think of the vibrations that make hands go numb. Due to the inherent structural defects of three-cylinder engines, the vibration issue is difficult to eliminate. The only solution is to use technological means to reduce the transmission of vibrations to the car body, thereby improving comfort. Compact size: Three-cylinder engines are small in size and light in weight, which reduces the overall weight of the vehicle and decreases fuel consumption. Small displacement: With only three cylinders, the engine has a small displacement, aligning with the national call for emission reduction and energy conservation. It also reflects the environmental responsibility of a major corporation.
