What happens when the thermostat of Wuling Hongguang fails?
2 Answers
The following situations occur when the thermostat of Wuling Hongguang fails: 1. The temperature difference between the upper and lower hoses of the radiator is noticeable when touched by hand, with the upper hose being very hot and the lower hose being very cold; 2. The electric fan operates continuously at high speed. Due to the excessively high water temperature, the vehicle's computer controls the electric fan to cool down rapidly, causing it to run continuously; 3. The engine fault light on the dashboard illuminates, and the fault code read by the decoder indicates a vehicle temperature sensor malfunction. Generally, the temperature sensor and thermostat are designed together, so when the thermostat fails, it will report a temperature sensor fault.
My Wuling Hongguang had a thermostat issue before, which was really nerve-wracking. Once the thermostat fails, the engine temperature goes haywire. It either stays too low, causing incomplete fuel combustion, increased fuel consumption, weak power, and severe shaking, or the temperature suddenly spikes, possibly triggering the coolant temperature warning light. Prolonged operation under these conditions can lead to severe engine carbon buildup and performance degradation at best, or overheating and cylinder scoring at worst, costing thousands in repairs. When driving, it's advisable to keep an eye on the dashboard. If you notice abnormal fluctuations in coolant temperature, immediately pull over to a safe spot and have a professional technician inspect it. Never delay, as the problem will only worsen, affecting both driving safety and financial costs.
