What causes the car temperature gauge to be too high?
2 Answers
Possible causes: There may be leaks in the engine, such as water pump leaks, pipe damage, radiator damage, etc.; The thermostat in the engine cooling system has malfunctioned, causing the water temperature to be too high. Because the thermostat cannot open, the flow of coolant inside the engine is obstructed, leading to excessively high coolant temperature. The cooling fan in the engine cooling system is not working properly, resulting in poor heat dissipation of the coolant. Below are related explanations: 1. Insufficient coolant: Coolant leakage can cause the water temperature to rise. At this time, check for any signs of coolant leakage. If there is, the leaking components should be repaired as soon as possible. If there is no leakage, the corresponding coolant should be added promptly. 2. Coolant: Coolant, whose full name should be antifreeze coolant, means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during parking in cold seasons.
I remember last time when I was driving, the temperature gauge suddenly shot up, which gave me a scare. It might be due to too little coolant in the radiator or a possible leak, as the cooling system couldn't dissipate heat effectively. I immediately pulled over to check: opened the engine hood to see if the radiator water level was below the minimum line, and if so, added some distilled water or special coolant; if the radiator was clogged with dust or bugs, it could also overheat, so I simply rinsed the surface with water; a non-working fan is a big issue, so I listened for any humming sound. If the thermostat is stuck, the coolant can't circulate, causing the engine temperature to skyrocket. If you can't handle it, you'll need to call a tow truck, as forcing the car to keep running could burn out the engine cylinder head, leading to expensive repairs. I recommend checking the coolant every three months to avoid regretting it only after a problem occurs.
