What to Do When Prompted with Overheating Coolant Temperature?
2 Answers
A prompt indicating overheating coolant temperature suggests that the coolant temperature has exceeded the specified limit or the coolant level is insufficient. You should immediately stop the vehicle to inspect and replenish the coolant. Below are specific reasons for coolant leakage: 1. Minor leaks in the radiator inlet and outlet hoses: You can use adhesive tape or a cloth coated with grease to wrap the leaking area, then secure it with wire to prevent further leakage. 2. Severe damage to the radiator inlet and outlet hoses: Cut off the damaged section, find a plastic tube of suitable diameter and length to sleeve over the hose in the middle, and secure it with wire for emergency use.
If the dashboard indicates the coolant temperature is too high, I will immediately find a safe place to stop and turn off the engine. Never continue driving, otherwise the engine may be severely damaged or cause more serious malfunctions. Wait until the car has completely cooled down (approximately thirty minutes) before checking if the coolant reservoir level is too low. If it is low, add distilled water or specialized coolant as an emergency measure, but be careful not to burn your hands. After adding, start the engine and observe whether the temperature returns to normal. If it remains high or there are unusual noises, promptly contact a tow truck to take the car to a repair shop for inspection—possible issues include a clogged radiator, damaged water pump, or fan malfunction. While driving, always pay attention to changes in the temperature gauge to avoid overheating caused by long-distance fatigue driving. Regular maintenance checks of the cooling system can help prevent such problems.
