What is the normal temperature range for antifreeze?
1 Answers
The normal temperature for antifreeze is indicated by the center of the gauge, which is 90 degrees Celsius. Antifreeze is an essential component of a car's engine. It circulates within the engine's cooling system, carrying away excess heat generated during engine operation, ensuring the engine operates at its optimal working temperature. Below are the key functions of automotive coolant: 1. Winter antifreeze protection: To prevent the coolant from freezing when the car is parked in winter, which could cause the radiator or engine block to crack, the freezing point of the coolant should be approximately 10 degrees Celsius below the lowest temperature in the region, preparing for sudden weather changes. 2. Corrosion prevention: Coolants contain a certain amount of anti-corrosion additives to prevent corrosion within the cooling system. 3. Scale prevention: The coolant should minimize scale formation during circulation to avoid clogging the pipes and impairing the cooling system's heat dissipation function. 4. Boiling prevention: Coolants that meet national standards typically have a boiling point above 105 degrees Celsius. Compared to water's boiling point of 100 degrees Celsius, coolant can withstand higher temperatures without boiling (overheating), meeting the cooling demands of high-load engines to some extent.
