What is the normal temperature of coolant?
1 Answers
The normal temperature is indicated when the needle points to 90°C at the center of the gauge. After starting the vehicle, the antifreeze temperature rises rapidly. Once the needle reaches the central position, the heat exchange reaches equilibrium and the antifreeze temperature stabilizes. Generally, it's optimal to start driving when the temperature reaches the middle position. More information about coolant is as follows: 1. Introduction: Its full name should be antifreeze coolant, meaning it has antifreeze functionality. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold seasons when the vehicle is parked. However, it's important to correct a common misconception: antifreeze is not just for winter use; it should be used year-round. In regular vehicle maintenance, the engine antifreeze should be replaced every year. 2. Function: Automotive coolant is used to regulate the engine's temperature. If the temperature is too high, the engine cannot operate within its normal temperature range. Moving parts may expand due to heat, disrupting normal clearance tolerances, and lubricants may burn, degrade, or lose viscosity due to high temperatures, leading to seized components or accelerated wear. The normal operating temperature should be around 90°C; temperatures significantly higher or lower can cause damage to the vehicle.
