What Does It Mean When the Coolant Light Comes On?
1 Answers
Reasons for the coolant light coming on: 1. Low coolant level, which typically occurs right after starting the engine, can be resolved by simply adding more coolant; 2. If the light comes on during driving, it may be due to coolant boiling. In this case, you can shift to neutral and coast to allow air cooling. Coolant, short for antifreeze coolant, is designed to prevent freezing in cold weather, thereby avoiding radiator cracks and engine cylinder block damage caused by frozen coolant. Coolant consists of three components: water, antifreeze, and additives. Based on the antifreeze agent used, it can be classified into alcohol-based, glycerol-based, and ethylene glycol-based coolants.
