What to Do When the Engine Overheats and the Air Conditioning Turns Off?
1 Answers
Wait for the engine to cool down before turning the air conditioning back on. Even if the issue is resolved immediately, do not turn on the air conditioning right away, as the motor temperature remains high and requires cooling. Operating it prematurely can easily lead to motor burnout. Solutions for engine overheating: 1. During traffic jams or prolonged idling, if the engine temperature gauge shows excessively high readings, the electronic fan operates at high speed for too long, engine noise increases, and the problem becomes most noticeable when using the air conditioning in high temperatures. Solution: Check if there is excessive dust between the condenser and the radiator. Clean thoroughly with high-pressure air to ensure optimal cooling performance for both the radiator and condenser. 2. When using the air conditioning in high temperatures, if the idle speed is unstable, the RPM fluctuates significantly, acceleration is sluggish, or the engine makes unusual noises. Solution: While the engine is warm, check the temperature difference between the upper and lower radiator hoses. If the difference is too large, inspect the thermostat's opening and whether the water pump is experiencing speed loss. 3. If the engine is difficult to start after being turned off for over ten minutes when warm, or if it stalls automatically while driving. Solution: After the engine is warm, check the coolant reservoir's upper return hose for proper coolant flow. Poor or blocked return flow can cause the engine temperature to rise excessively.
