Why is the radiator always overheating?
1 Answers
The reasons for the radiator always overheating are: 1. The cooling fan is malfunctioning. When the car is running at high speed, the heat generated cannot be transferred to the coolant in time, which affects heat dissipation, leading to an increase in coolant temperature and causing issues like boiling over; 2. The car water pump is malfunctioning, with issues such as seized bearings or damaged impellers. Common impeller damages include cracks or loosening from the pump shaft, which slows down the coolant circulation speed and causes the engine temperature to rise excessively; 3. The radiator has many pores formed by cooling fins, which are prone to being clogged by lint, sludge, etc., resulting in poor ventilation and reduced cooling efficiency. This can easily lead to high water temperature in summer, and timely cleaning of the radiator can solve the problem.
