What is the normal temperature of a car's water temperature while driving?
2 Answers
The normal water temperature of a car while driving is between 80 to 90 degrees Celsius. The water temperature refers to the temperature of the coolant. The reasons for a car's water temperature being too high are: 1. Scale deposits in the radiator and engine water jacket, causing poor heat dissipation and a rise in water temperature; 2. A damaged thermostat, preventing the coolant from circulating into the radiator; 3. A damaged water pump or slipping drive belt causing poor water pump performance; 4. Insufficient coolant leading to poor engine heat dissipation; 5. A malfunctioning or low-speed cooling fan. The solutions for a car's water temperature being too high are: 1. Clean the scale deposits in the engine; 2. Inspect or replace the thermostat; 3. Inspect or replace the water pump; 4. Add coolant to the engine; 5. Check the cause of the fan malfunction or low speed.
After driving for so many years, I've found that coolant temperature is a really sensitive indicator that needs constant monitoring. During normal driving, the temperature gauge needle usually stays in the middle zone, around 80 to 90 degrees Celsius, which is the optimal temperature range for smooth engine operation and high fuel efficiency. If it's too low, say below 60 degrees, it can cause poor oil circulation and increased wear; if too high, exceeding 100 degrees might lead to boiling and smoking, or even component damage. From my experience, the temperature gradually rises within minutes after starting, so keep monitoring the dashboard and avoid prolonged idling in traffic to prevent overheating. Regularly changing coolant and checking the radiator fan can also prevent issues. Remember, don't ignore minor problems - if you notice anything unusual, stop and check immediately. Safety always comes first.
