What This Part is Used For
The thermostat regulates the flow of cooling water through the engine. It stays closed while the engine is cold to help the powerhead warm up efficiently, then opens as the engine reaches its intended operating temperature.
Proper thermostat operation supports consistent engine temperature, reliable idle quality, efficient combustion and dependable cooling-system performance.
Reasons to Inspect or Replace the Thermostat
A thermostat that remains closed may restrict cooling-water circulation and contribute to overheating.
A thermostat stuck open may prevent the engine from reaching its intended operating temperature.
Thermostats are commonly inspected during water-pump and other cooling-system maintenance.
Corrosion, salt and debris can interfere with thermostat movement and cooling-system performance.
