What is the reason for the coolant not returning to the overflow tank?
1 Answers
The coolant not returning to the overflow tank is due to a degraded thermostat or the thermostat not reaching its operating temperature. Here are some precautions regarding the use of the car radiator: 1. Prevent the car from overheating: The car radiator is most afraid of overheating, which means the temperature is too high. Always monitor the temperature displayed on the dashboard while driving. If the temperature is found to be too high, stop and check immediately. 2. Stop and check: If the engine starts emitting smoke, the user should stop the car promptly and open the engine hood to increase the cooling rate. It is best to park in a well-ventilated area, avoiding tunnels or enclosed spaces. 3. Regularly replace the coolant: Over time, the coolant in the car radiator can accumulate various impurities, affecting its cooling efficiency. Therefore, it is essential to replace the coolant periodically as specified in the vehicle's manual.
