You may also see temperature warnings on your gauge or inconsistent temperature readings.

This helps bleed trapped air from the cooling system and improves cooling water circulation at idle speeds.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eCan I test my old thermostat before replacing it?\u003c\/summary\u003e\n  \u003cp\u003eYes. You can suspend the old thermostat in a pot of water with a thermometer. Heat the water and observe the temperature at which the thermostat begins to open. For this model, it should start opening around 60°C (140°F). If it doesn't open, or opens at a significantly different temperature, it should be replaced.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eMy engine model is listed, but the part photo looks slightly different.
