Why is the heater not working after replacing the coolant?
1 Answers
The reasons why the heater is not working after replacing the coolant are: 1. Radiator blockage; 2. Cylinder head gasket failure causing coolant deterioration. The functions of automotive coolant are: 1. Providing anti-corrosion protection for cooling system components; 2. Preventing scale buildup to avoid reducing the radiator's cooling efficiency; 3. Ensuring the engine operates within the normal temperature range. Precautions for using coolant include: 1. Regularly checking the coolant level and replenishing it promptly if it falls below the lower limit; 2. Observing whether the coolant has turbid sediments, and replacing it in time if turbidity is found; 3. Different vehicle models have coolants of different colors, which should not be mixed; 4. Before winter, measure the freezing point of the coolant to prevent it from freezing.
