What are the solutions for car overheating?
2 Answers
Causes of car overheating include water pump damage, dirty radiator surface, lack of coolant, and thermostat damage, each with different solutions. Details are as follows: Water pump damage: When the water pump is damaged, coolant cannot circulate in the cooling system, leading to car overheating. In this case, the water pump needs to be replaced. Dirty radiator surface: When the radiator surface is covered with dirt, heat conduction is poor, and heat cannot be dissipated into the air immediately, which can cause engine overheating. At this time, the radiator needs to be cleaned, and if necessary, replaced with a new one. Lack of coolant: When coolant is partially or completely missing, there is no cooling medium in the cooling system, and engine heat cannot be dissipated, leading to overheating. In this case, the coolant needs to be replenished. Thermostat damage: When the thermostat is damaged and stuck in the closed position, the coolant inside the engine remains in a small circulation loop, preventing the coolant in the radiator from participating in the circulation and heat dissipation. This results in higher water temperature when the vehicle is idling or driving at low speeds, and the faster the speed, the higher the temperature. In this case, the thermostat needs to be replaced.
When the car overheats, I always find a safe place to stop, turn off the engine, and wait for it to cool down. I usually pay attention to the temperature gauge while driving. If the car boils over, immediately turn off the air conditioning and switch the heater to full blast to dissipate the heat. After the car cools down, check if the coolant is sufficient. If not, add some tap water or purified water as an emergency measure, but don't open the hood too quickly to avoid burns. If the fan isn't working, it might be an issue with the motor or wiring, so check the fuses. During regular maintenance, ask the mechanic to inspect the water pump, belts, and radiator for any blockages to avoid breakdowns on the road. Last summer, my friend's car had a broken fan and caused a whole day of trouble, so don't ignore small issues—safety is the most important.
