Is a car temperature of 90 degrees normal?
2 Answers
When driving normally, the optimal temperature range for a car is between 70~90℃. If the temperature exceeds 90 degrees Celsius and remains high, it indicates abnormal engine operation. A car engine requires a specific operating temperature to function properly; temperatures that are too high or too low can adversely affect the engine's normal operation and performance. Below is an introduction to car engines: Classification of engines: Based on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines. Principle of engines: Common gasoline and diesel engines are reciprocating piston-type internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easier to start, and have lower manufacturing costs. Diesel engines have higher compression ratios, better thermal efficiency, and superior economic and emission performance compared to gasoline engines.
When I first started driving, I also thought 90°C was a bit high for coolant temperature and worried about overheating. Actually, most vehicles operate normally with coolant temperatures fluctuating between 85°C and 105°C – 90°C is perfectly within the safe range. My car has been running for almost five years now, and during daily commutes, the temperature usually stabilizes around 90°C with smooth engine operation and normal noise levels. You should only be concerned if the temperature rises above 95°C or even 100°C during highway driving or traffic jams – that’s when you might want to check coolant levels or whether the radiator fan is working. Slightly higher temperatures are also common when running the AC in summer. Make it a habit to monitor the temperature gauge and don’t skip maintenance, like annual coolant replacement, to prevent minor issues. Remember, 90°C is the sweet spot for your car – don’t let unnecessary worries ruin your driving pleasure.
