What Causes High Temperature in a Car Radiator?
1 Answers
The causes of high temperature in a car radiator are as follows: 1. Insufficient coolant: It should be promptly added to the appropriate level. Note that you should not immediately open the radiator cap or reservoir cap after parking, as the internal pressure is too high and opening it may cause instant spraying. Wait until the temperature cools down slightly before slowly opening the reservoir cap. 2. Faulty cooling fan: When the car is running at high speed, the generated heat cannot be promptly transferred to the coolant, affecting heat dissipation and causing the coolant temperature to rise, leading to issues like overheating. 3. Dirty radiator: The radiator has many pores formed by cooling fins, which can easily get clogged with lint, sludge, and other debris, reducing airflow and worsening heat dissipation. This can easily cause high water temperature in summer, and washing the radiator promptly can resolve the issue.
