How to Check the Condition of a Thermostat?
1 Answers
Methods to check the condition of a thermostat: 1. Check the opening temperature of the thermostat valve. The thermostat is installed at the outlet of the engine water jacket. After removing the thermostat, immerse it in water and gradually heat the water. If the main valve opening temperature does not meet the requirements or fails to close properly at room temperature, replace the thermostat. 2. When the temperature is below 75 degrees, check if the valve is completely closed. If it is not fully closed, replace the thermostat. 3. Check the lift of the thermostat valve. When the water temperature is heated to 93 degrees, the lift of the thermostat valve should be greater than 8.5mm or more. If the valve lift does not meet the specified requirements, replace the thermostat.
