What is the normal temperature displayed for car coolant?
1 Answers
Car coolant temperature displaying 90 degrees Celsius is normal. For proper operation, a car engine needs to reach a certain temperature - neither too high nor too low, as both extremes are detrimental to normal engine operation and performance. The temperature shown on the car's coolant gauge indicates the temperature of the coolant. To ensure the engine operates within the normal temperature range, vehicles are equipped with an engine coolant temperature sensor, typically displayed separately on the coolant gauge. If the antifreeze temperature becomes too high, an alarm will be triggered. After starting the car, the antifreeze temperature rises rapidly, causing the needle on the coolant gauge to reach the middle position. Once equilibrium is achieved at this point, the temperature stabilizes and won't rise further. This explains why warming up the engine is necessary after the car has been parked for some time before driving.
