Can You Still Drive When the Car Coolant Light Comes On?
1 Answers
When the car coolant light comes on, you should not continue driving, as it indicates either a lack of coolant or a malfunction in the cooling system. The functions of coolant: 1. Provides anti-corrosion protection for cooling system components; 2. Prevents scale buildup, avoiding reduced radiator efficiency; 3. Ensures the engine operates within the normal temperature range. Precautions for using coolant: 1. Do not mix different types of antifreeze; 2. Do not open the radiator cap or drain valve immediately after driving; 3. When replacing coolant, ensure all old antifreeze is completely removed and the radiator is thoroughly cleaned. Steps for replacing coolant: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze; 2. Flush the engine cooling system; 3. Add new antifreeze when the engine is cool, filling it up to the maximum mark on the radiator.
