What Are the Causes of Sudden Engine Overheating?
1 Answers
Engine suddenly overheating causes are: 1. The fan motor is not working or the fan clutch is faulty, preventing normal cooling; 2. The three-way catalytic converter is blocked or the pipe is broken, causing exhaust obstruction and leading to engine overheating; 3. The cooling system pipe is broken, causing coolant loss and preventing the heat dissipation from functioning normally; 4. The water pump, after long-term use, has highly worn parts that have fallen off; 5. Excessive scale deposits on the outer wall of the cylinder liner, preventing the heat generated by the cylinder from being transferred to the cooling water. The methods to deal with sudden engine overheating are: 1. Repair the fan motor and fan clutch; 2. Clean the scale on the outer wall of the cylinder liner; 3. Add cooling water; 4. Replace the three-way catalytic converter.
