What are the reasons for the high water temperature in Jianghuai Junling?
4 Answers
Cooling system leakage leading to insufficient coolant; The radiator fan is stuck or damaged and cannot perform the cooling function; Prolonged high-speed driving can easily cause the water temperature to be too high; Other common reasons include: broken fan belt, leakage in the radiator or water pipes, thermostat failure, oil leakage, water pump failure, etc. Below is relevant information: 1. Solutions: For vehicles experiencing high water temperature due to prolonged driving, you can pull over, turn on the hazard warning lights, and let the vehicle cool down naturally; A damaged radiator fan also requires finding the nearest repair shop for inspection as soon as possible. 2. Hazards of high water temperature: The normal water temperature of an engine is between 85-95 degrees Celsius. When the water temperature is too high, the viscosity of the engine oil becomes thinner, reducing its lubricating performance. High-speed components such as pistons and valves are prone to deformation, causing the engine to lose power. In severe cases, it can lead to cylinder scoring and crankshaft seizure, requiring major engine repairs.
I've been driving a JAC Junling truck for several years and have encountered high coolant temperature issues multiple times. The most common cause is insufficient coolant level - too little liquid can't provide proper cooling. During long-distance hauls, the fan may get stuck and stop rotating, especially in hot summer weather when heat dissipation is less effective. A leaking water pump due to aging can prevent proper coolant circulation. Once when I was hauling cargo up a steep slope, the temperature suddenly spiked - inspection revealed the radiator fins were clogged with mud. There was also an instance where the thermostat failed and stopped coolant flow. My recommendations: always check the reservoir level before trips to ensure it's not empty; avoid aggressive acceleration and reduce load during long hauls; regularly replace antifreeze and clean the radiator. Engine damage from overheating is costly and dangerous - early intervention saves money and ensures safety.
Having repaired vehicles for over a decade, I've frequently encountered high coolant temperature issues in JAC Junling trucks. The main causes include: coolant leaks leading to low fluid levels, inefficient water pump operation, stuck thermostats, and poor heat dissipation. Fan system failures such as burnt wiring or damaged blades preventing rotation. Faulty sensor readings may mislead the dashboard display while actual conditions are normal - diagnostic tools are required for verification under high-temperature conditions. A dirty radiator clogged with dust obstructs airflow and requires flushing. My repair approach starts with checking for leakage points and testing pump pressure. For maintenance, seasonal coolant replacement and descaling the pipes save trouble; avoid heavy loads and long uphill drives to prevent excessive strain. Never delay repairs to avoid costly cylinder scoring damage.
As a new driver, I haven't been driving my JAC Junling for long when the temperature gauge started frequently jumping to high levels, which made me nervous. I asked an experienced driver friend who taught me to first check the coolant reservoir and try topping it up with water. If the water pump is broken, the water flow won't circulate normally and is usually accompanied by unusual noises. If the radiator is dirty, you can simply rinse the fins. Listen to the fan to determine if it's spinning. When driving, avoid prolonged high-speed operation, especially during summer when carrying heavy loads or climbing hills, as it can easily lead to overheating. I've personally tried stopping in time to cool down, which is effective—don't let the problem worsen, or the repair costs will be high. Temperature control is directly related to safety.
