What to Do When the Engine Temperature Is Too High?
1 Answers
Solutions for excessively high engine temperature: 1. Find a safe place to pull over and let the vehicle idle; do not turn off the engine, as shutting it down will stop both the cooling fan and coolant circulation, making the engine even hotter. 2. Open the hood to increase air circulation. Wait for the water temperature to drop before slightly loosening the radiator cap to release internal steam, then fully open it. 3. Do not add coolant immediately. Due to thermal expansion, boiling water in a sealed container creates pressure. Opening the radiator cap right after boiling may cause hot water to spray out, potentially leading to burns. 4. Check for leaks in the radiator hoses and ensure the coolant level is sufficient. If no coolant is available, mineral water can be used temporarily, but it must be replaced with proper coolant later.
