What is the normal temperature range for a vehicle's coolant?
1 Answers
Generally, the normal temperature range for a vehicle's coolant is between 80 to 90 degrees Celsius. The coolant temperature refers to the temperature of the antifreeze. The reasons for high coolant temperature in a car include: 1. Scale deposits in the radiator and engine water jacket, leading to poor heat dissipation and rising temperature; 2. A faulty 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 antifreeze leading to poor engine heat dissipation; 5. A malfunctioning or low-speed cooling fan. Solutions for high coolant temperature include: 1. Cleaning the scale deposits inside the engine; 2. Inspecting or replacing the thermostat; 3. Inspecting or replacing the water pump; 4. Adding antifreeze to the engine; 5. Checking the cause of the fan malfunction or low speed.
