Is it normal for the car's front hood to get hot?

It is not normal for the car's front hood to get hot. Here are some precautions for using the car engine: Avoid driving in neutral: The engine itself has a fuel cut-off function during deceleration, and driving in neutral is not conducive to fuel economy. Pay attention to observation when using the vehicle: If you find oil on the ground, determine whether there is an engine oil leak and communicate with the car 4S store in time to eliminate potential safety hazards. Do not turn off the engine immediately: For cars equipped with turbochargers, do not turn off the engine immediately after high-speed driving or climbing a slope. Let the engine idle for 10 minutes before turning it off. Cars with turbochargers form carbon deposits several times faster than naturally aspirated cars.
For those who have been driving for years, it's completely normal for the engine hood to get warm when the engine is running. It's just like how the body heats up after exercise. Especially in summer when the AC is on or after highway driving, feeling a warm hood is nothing unusual. However, if it's too hot to touch or you smell something burning, that's a red flag. It could indicate a cooling system issue, like a coolant leak or a malfunctioning fan. After long trips, I always make it a habit to check the hood temperature and glance at the coolant temperature gauge on the dashboard—if the needle is in the middle, everything's fine. A quick reminder: don't let kids touch the hood right after parking, as it can easily burn their hands.
I can totally relate to this. The other day after a long highway drive, I noticed the hood was steaming hot. It's normal for the engine to reach working temperatures of 80-90 degrees Celsius, with heat transferring to the hood through metal conduction. But there are two key things to watch for: First, if you can keep your palm on the hood for more than five seconds, it's normal heat; if you can't even last one second, it's time for a check-up. Second, look for any abnormalities like white smoke or dripping coolant. Once my car's cooling fan failed, and the hood got so hot you could fry an egg on it, causing the temperature gauge to max out. In such cases, you must pull over immediately to check the coolant level, or the engine could be ruined. Also, never rinse the hood with water right after parking—the rapid temperature change from thermal expansion and contraction can damage the paint.
