What to Do When the Water Temperature is Normal but There's No Warm Air?
1 Answers
When the water temperature is normal but there's no warm air, the following methods can be used to address the issue: Check if the radiator is leaking: Open the radiator and see if the water level is below the MIN mark. If the water level is very low, it's likely due to a leak. Add water, open the exhaust screw near the engine to release air, and check for leaks. Air in the radiator can also cause the water temperature to rise. Leaks usually occur when the engine is cold, so check after the engine has cooled down. Pay attention to whether there's any leakage at the heater hose connections leading to the cabin. If there are no leaks but the water level drops below the minimum mark within a week or half a month after filling, it might be due to a faulty cylinder gasket causing water to seep into the engine. Replace the water temperature sensor: If the engine doesn't overheat but only shows a high water temperature reading, it might be due to an inaccurate water temperature sensor, which needs to be replaced. Replace the thermostat: If the thermostat fails to open, preventing the circulation of hot and cold water, and the water temperature reaches 90 degrees, open the hood and feel the hoses near the engine—they should be hot, but the radiator should not be. If the radiator isn't hot, it means the water isn't circulating. Normally, both sides should be hot; otherwise, the thermostat needs to be replaced. Replace the water pump: Over time, the blades of the water pump can become damaged or clogged. If the water pump isn't functioning well and can't circulate water, the water temperature will rise quickly, requiring the water pump to be replaced.
