What Causes the Jetta's High Water Temperature and Non-rotating Fan?
1 Answers
The reasons for the Jetta's high water temperature and non-rotating fan are: damage to the cooling system's electronic components (thermostat, cooling fan); poor radiator heat dissipation; or insufficient coolant. Insufficient coolant: Coolant leakage or insufficiency can cause the water temperature to rise. Check for any signs of coolant leakage, and if found, promptly repair the leaking pipes, etc. If there is no leakage, add the same brand of coolant in time. However, it is not recommended to add water, especially in winter, as even if it does not cause a malfunction, it will dilute the coolant. Cooling fan malfunction: A malfunctioning cooling fan can result in the heat generated during high-speed vehicle operation not being transferred to the antifreeze in time, affecting heat dissipation and subsequently causing the antifreeze temperature to rise.
