What are the causes and solutions for excessively high car coolant temperature?
1 Answers
Car coolant temperature too high causes: 1. Cooling system leakage leading to insufficient coolant; 2. Stuck or damaged radiator fan failing to provide cooling function; 3. Prolonged high-speed driving easily causes overheating; 4. Broken fan belt; 5. Radiator or hose leakage. Solutions for high coolant temperature: 1. If discovering high temperature caused by coolant loss, add small amount of distilled water as emergency measure - note never open radiator cap when hot due to burn risk; 2. For overheating caused by prolonged driving, pull over safely, turn on hazard lights, and let vehicle cool naturally; 3. If radiator fan is damaged, locate nearest repair shop immediately for inspection; 4. When replacing damaged thermostat, block the small circulation loop to ensure all coolant passes through radiator for cooling.
