How to Solve the High Water Temperature Issue in Pajero?
2 Answers
If the car's water temperature is too high, it is necessary to stop the vehicle promptly for cooling down, and then check whether the antifreeze in the engine is sufficient. Insufficient antifreeze can cause the car's water temperature to rise, and timely replenishment is required to maintain the water temperature within a relatively balanced range. The following are the reasons for high water temperature: Thermostat failure in the engine cooling system leading to high water temperature: Because the thermostat cannot open, the flow of coolant inside the engine is hindered, resulting in excessively high coolant temperature. Improper functioning of the cooling fan in the engine cooling system: This leads to poor heat dissipation of the coolant. Therefore, the water temperature light comes on, causing the coolant temperature to be too high. Failure of the water pump in the engine cooling system: The water pump does not rotate smoothly, leading to poor coolant flow. As a result, the water temperature light comes on, and the coolant temperature becomes too high.
I remember during a long-distance trip in my Pajero when the water temperature suddenly spiked—it was really scary. At that time, I pulled over, let the engine cool for half an hour, and opened the radiator cap to check the coolant level, only to find it had dropped significantly—likely due to a minor leak. After topping it up with a coolant mixture, the temperature returned to normal. But that experience reminded me to regularly inspect the radiator and ensure the fan is working: if the fan isn’t spinning, it could mean a faulty motor or relay, requiring part replacement. Too much dust buildup on the radiator can also block heat dissipation, so periodic flushing helps prevent this. High temperatures can severely damage the engine, even leading to blown head gaskets in extreme cases, so never force-drive when issues arise—get it checked by a professional shop ASAP. Routine maintenance should never overlook the cooling system.
