What are the reasons for engine stalling due to high temperature?
3 Answers
Engine stalling due to high temperature is generally caused by excessive water temperature. The following are detailed explanations and solutions for engine high-temperature stalling: Unreasonable equipment installation position: Excessive distance between the radiator and the engine, the fan being outside the air duct, or the air conditioning condenser blocking the radiator. Solution: If there is sufficient space in the engine compartment, change the installation position of the air conditioning condenser. If the generator has sufficient power output, install an electric fan in front of the condenser. Engine vapor lock: After draining the engine or refilling it when severely low on water, air may not be completely expelled from the engine, causing vapor lock and leading to excessive engine temperature. Solution: After refilling, run the engine for a few minutes, open the filler cap, and top up the water again. Component failures in the engine cooling system: Damaged water pump, faulty thermostat, excessive scale in the cooling system, clogged radiator tubes, or debris between radiator tubes can all cause high engine water temperature. Solution: Inspect and replace the relevant components.
As a veteran driver with over 20 years of experience, I've seen plenty of engine overheating and stalling cases. The main causes are cooling system failures - insufficient coolant, radiator clogged with dirt preventing heat dissipation, broken fan not spinning, or water pump leakage causing poor circulation. This happens more frequently during summer long-distance trips with AC on. I once experienced sudden temperature spike and automatic engine shutdown due to a stuck thermostat. The key is to pull over immediately, turn on hazard lights, and wait for cooling before checking/refilling fluids - safety first. Preventive measures like regular coolant replacement and radiator cleaning are crucial. Mechanics say blown head gasket or loose fan belt can also cause this - proper maintenance saves money and hassle while avoiding roadside embarrassments.
I was terrified when my newly purchased car, less than a year old, experienced engine overheating and stalled. That time on the highway, the dashboard warning lights flashed red, and the car suddenly stopped. The possible causes could be insufficient engine oil leading to lubrication failure and a surge in friction heat, or a malfunctioning cooling fan. After towing, the mechanic found that the water pump seal was broken, causing fluid loss. Since then, I've learned my lesson and check the fluid levels every month—don't be careless. New drivers should pay extra attention, especially during hot seasons, and frequently check fluid levels to ensure safety. If an incident occurs, stop immediately and seek help—never risk driving further.
