What This Thermostat is Used For
The thermostat controls coolant flow through the engine. When the engine is cold, it remains closed to help the powerhead reach operating temperature. As the engine warms, the thermostat opens to allow cooling water to circulate.
A properly functioning thermostat supports consistent engine temperature, clean combustion, dependable idle quality and correct cooling-system operation.
Reasons to Inspect or Replace the Thermostat
A thermostat stuck closed can restrict coolant flow and contribute to overheating.
A thermostat stuck open can prevent the engine from reaching its intended temperature.
Thermostats are commonly inspected during water-pump and cooling-system maintenance.
Salt, scale and debris can interfere with thermostat movement and sealing.
