What Causes the Car Water Warning Light to Illuminate?
1 Answers
The illumination of the car water warning light indicates that the engine's water temperature is too high. Detailed reasons for the car water warning light turning on are as follows: 1. Coolant issues: The normal operating temperature of an engine is around 90 degrees Celsius. If the temperature is too high, it may be due to insufficient coolant in the antifreeze reservoir or excessive water mixed into the antifreeze. The purpose of antifreeze is to help cool the entire radiator system. When there is a deficiency or too much water, the engine may "overheat." 2. Radiator problems: This includes three aspects: (1) Leakage in the radiator body, corrosion inside the radiator, or damage from impact. Check for any signs of leakage around the engine. (2) Dirt such as mud, lint, or gravel on the radiator surface, or scale from tap water, causing localized temperature increases in the radiator. (3) Leakage in the hoses connected to the radiator, leading to insufficient cooling water and elevated water temperature. 3. Water pump issues: The circulation of cooling water is driven by the water pump, which pressurizes the cooled water from the radiator into the engine water jacket, forcing the heated coolant back to the radiator for cooling. If the water pump fails to operate properly, it cannot generate sufficient pressure to circulate the coolant to the radiator, resulting in poor coolant circulation and excessive water temperature. If the water pump is faulty, it needs to be replaced with a new one.
