Symptoms of Low Water Level in Vehicle Radiator?
2 Answers
When the car radiator is low on water, the dashboard will illuminate a warning light to alert the driver. Symptoms of low water level in vehicle radiator: 1. Radiator scale lines: After opening the engine hood, you can see the coolant expansion tank, which has min and max scale lines. If the coolant level is below the min line, it indicates low water level. 2. Antifreeze: Modern car engines are water-cooled engines, which rely on the continuous circulation of coolant to dissipate excess heat. The coolant in water-cooled engines is generally antifreeze coolant, commonly referred to as antifreeze.
Once when I was driving to the mountains for fun, I noticed the temperature gauge needle climbing rapidly during the uphill climb, almost reaching the red line. I quickly pulled over and popped the hood, only to find the coolant reservoir level so low it was nearly invisible, with waves of hot air and steam billowing out. After years of driving, I finally understood that abnormal temperature rise is the most direct sign of low coolant level, which you can clearly see on the dashboard. If you keep pushing the car under these conditions, the power becomes noticeably sluggish—you press the gas but the speed won't pick up. This issue becomes even more apparent during summer traffic jams; when you turn on the AC, you'll clearly feel hot air blowing out, with the vents almost burning your face. So now I've made it a habit to check the coolant reservoir before long trips, ensuring the level stays between the high and low marks.
