How to Deal with Overheating Engine Coolant Temperature?
2 Answers
Methods to handle overheating engine coolant temperature: 1. Replace the coolant temperature sensor. If the engine isn't boiling over but only shows high temperature, it might be due to an inaccurate coolant temperature sensor. In this case, replacing the sensor should solve the problem. 2. Replace the thermostat. A thermostat that fails to open can prevent the circulation of hot and cold coolant. After the temperature reaches 90 degrees, open the hood and feel the hoses near the engine. If the hoses aren't hot, it indicates no coolant circulation. Normally, both sides should be hot. If not, the thermostat needs replacement. 3. Replace the water pump. Over time, the impeller of the water pump can get damaged or clogged. A malfunctioning water pump can't circulate the coolant properly, leading to rapid temperature rise, which requires replacing the water pump.
I've been driving for many years, and overheating is a common issue. The top priority is to immediately slow down and pull over, then pop the hood but stand back to avoid steam burns. Wait about ten minutes for the engine to cool down, then check the coolant reservoir level—if it's low, top it up with distilled water or coolant. Don’t rush to open the cap, as high pressure can cause hot liquid to spray and injure you. If the fan isn’t spinning, it might be a sensor or electrical issue. To stay safe, just call a tow truck and head to a repair shop—better to avoid turning a small problem into a major repair. During regular maintenance, always check the antifreeze and cooling system. A quick inspection before long trips can significantly reduce risks. In short, stay calm and take it step by step—that’s the most reliable approach.
