What are the causes of high temperature in a car engine?
2 Answers
Causes of high temperature in a car engine include: 1. Fan motor not working or fan clutch failure; 2. Blocked or ruptured catalytic converter pipes; 3. Ruptured pipes in the cooling system; 4. Long-term use of the water pump leading to severe wear and part detachment; 5. Unstable pressure in the radiator cap causing spring loosening and improper sealing. Solutions for high engine temperature are: 1. Open the radiator cap, start the engine, and observe if there is any water circulation in the radiator; 2. Remove and inspect the thermostat; 3. Check if the radiator surface is blocked; 4. Inspect the fan belt to ensure proper tension.
Last time I drove to the mountains for vacation, the engine suddenly gave a high-temperature warning, which really scared me. I immediately pulled over to check and found that the main cause was insufficient coolant, as some fluid had leaked due to aging hoses. This is what happens when there's a problem with the cooling system, like a clogged radiator or a malfunctioning fan. When the car is climbing steep slopes at high speed, the heavy load on the engine can also cause the temperature to spike. At the time, I checked the fan and found it wasn't spinning—probably a motor issue. High temperatures are extremely dangerous and can cause engine components to deform or even crack. I want to remind everyone to check the coolant level and fan before long trips, and clean any dirt off the radiator to prevent such incidents. Safety on the road comes first!
