What is the normal temperature of car coolant?

[Jayden]

Car coolant's normal temperature is indicated by the center of the gauge at 90 degrees. Normally, after turning on the ignition switch, the coolant temperature gauge's pointer should deflect from 100°C towards 40°C, then gradually indicate the correct coolant temperature. Here's some information about coolant: 1. The full name of coolant is antifreeze coolant. It prevents the engine from freezing in winter and cools the engine when it generates high temperatures during operation, ensuring the vehicle can function properly in various environments. 2. Car coolant is composed of water, antifreeze, and additives. Based on its composition, it can be classified into alcohol-based, glycerol-based, and ethylene glycol-based types.
