What are the reasons for the insufficient heating in BYD F3?
1 Answers
BYD F3 insufficient heating mainly has the following reasons: 1. Abnormal engine water temperature: If it remains at a low temperature and fails to reach the operating temperature, the heating will definitely not be hot. At this time, you can focus on checking whether the thermostat is always in the large circulation state, or whether the water temperature sensor signal is accurate, and then repair or replace the faulty component. 2. There is a significant temperature difference between the inlet and outlet pipes in front of the heating radiator: If this situation exists, it is definitely due to a clogged heating radiator, which needs to be disassembled, cleaned, or replaced. 3. The flow rate and temperature of the coolant entering the heating radiator do not meet the requirements: The temperature can be measured using an infrared thermometer to check the temperature difference in the pipes, and the flow rate can be determined through diagnostic data and fault storage from the testing equipment. Common issues include pump slippage or damage, and damage to the heating flow valve and coolant circulation valve. 4. There is air blockage in the coolant system: Commonly, this occurs when the coolant is replaced without proper air bleeding. A more special case is damage to the cylinder gasket. Standard coolant bleeding methods can be used for further confirmation.
