What are the reasons for the Lavida's heater not producing hot air?
1 Answers
The following are the reasons why the Lavida's heater may not produce hot air: 1. The thermostat is constantly open or opens too early: The cooling system prematurely enters the large circulation cycle, and with the low external temperature, especially when the car is moving, the cold air quickly cools the antifreeze, preventing the engine water temperature from rising and the heater from producing hot air. 2. The water pump impeller is damaged or slipping: The flow rate through the heater's small radiator is insufficient, preventing the heat from rising. 3. There is airlock in the engine cooling system: Airlock causes poor circulation in the cooling system, resulting in high water temperature and the heater not producing hot air. If there is always air in the cooling system, it is likely caused by a damaged cylinder gasket allowing air into the cooling system. If the inlet pipe of the heater's small radiator is very hot while the outlet pipe is relatively cool, this situation indicates a blockage in the heater's small radiator, which should be replaced.
