What to Do When the Water Temperature Is Not High but the Radiator Keeps Losing Water?
2 Answers
If the water temperature is not high but the radiator keeps losing water, possible causes include rising water temperature, malfunctioning water pump or thermostat, or poor sealing of the cylinder gasket. Here are some explanations regarding why the radiator keeps losing water even when the water temperature is not high: 1. Function of the Radiator: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature and protect it. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold. 2. Solutions: (1) Regularly check the radiator and replenish water in time. (2) Repair or replace the water pump or thermostat to restore normal function. (3) Ensure proper sealing of the cylinder gasket.
I've been driving for over ten years and often encounter coolant loss issues. When the engine temperature isn't high but coolant keeps decreasing, we need to troubleshoot step by step. First check for obvious leaks - inspect the water pump seals and hose connections for any wet marks. If you notice colorful stains under your parking spot, that confirms an external leak. If nothing's found, consider internal issues like a faulty cylinder head gasket allowing coolant into combustion chambers (check for white foam under oil cap). The heater core is another common leak point - you'll smell sweetness when using heater. Also, a deteriorated radiator cap seal can cause stealthy evaporation - try replacing it. If all else fails, visit a repair shop for pressure testing to prevent engine damage.
