What does the H symbol on the FAW Jiefang truck dashboard indicate?
2 Answers
The H symbol light on the FAW Jiefang truck dashboard indicates that the water temperature is overheating. 1. Water temperature gauge: A meter that displays the temperature of the coolant, measured in °C (Celsius). Its sensor is a thermistor sensor that can be screwed into the engine coolant passage. The thermistor determines the amount of current flowing through the water temperature gauge coil to drive the magnetic head pointer to oscillate. 2. Water temperature gauge and fuel gauge: Indicator lights are also displayed. The water temperature indicator light signals high water temperature, and the fuel indicator light signals that the fuel is nearing a low level, serving as an auxiliary reminder. Other indicator lights: 1. Windshield washer fluid indicator: This indicator light is used to display the amount of windshield washer fluid in the vehicle. It is usually off. When this indicator light turns on, it means that the windshield washer fluid in the vehicle is insufficient and needs to be refilled. After refilling the windshield washer fluid, the indicator light turns off. 2. Recirculation indicator: This indicator light is used to display the working status of the vehicle's air conditioning system. It is usually off. When the recirculation button is pressed, the vehicle closes the external circulation, and the air conditioning system enters the recirculation state, this indicator light automatically turns on. It turns off when recirculation is deactivated. 3. VSC indicator: This indicator light is used to display the working status of the vehicle's VSC (Vehicle Stability Control) system, commonly found in Japanese cars. When this indicator light turns on, it means the VSC system has been turned off. 4. TCS indicator: This indicator light is used to display the working status of the vehicle's TCS (Traction Control System), commonly found in Japanese cars. When this indicator light turns on, it means the TCS system has been turned off.
I've been driving a FAW truck for many years. When the H light on the dashboard comes on, it means the engine coolant temperature is too high. If the temperature gauge needle points to the H zone, it indicates a problem with the cooling system, such as low coolant level or a non-functioning fan. Last time it suddenly lit up while I was hauling cargo, I immediately pulled over, turned off the engine to inspect, and found the radiator was leaking. I promptly refilled the coolant, preventing a major incident. This situation requires special attention - continuing to drive could lead to engine seizure requiring costly overhauls, which is both expensive and dangerous. I recommend checking the temperature gauge before each trip, regularly inspecting coolant levels and hose seals to maintain good vehicle condition for worry-free long-distance driving.
