The thermostat is a temperature-controlled valve in the cooling system that regulates the flow of coolant through the engine. It stays closed when the engine is cold, allowing it to warm up quickly, and opens at the designed temperature to allow coolant to flow through the radiator for cooling. A stuck-closed thermostat causes overheating, while a stuck-open thermostat prevents the engine from reaching proper operating temperature.
In Spokane's cold climate, a stuck-open thermostat is particularly problematic. The engine takes much longer to warm up, the cabin heater blows lukewarm air, fuel economy suffers because the engine management system stays in cold-enrichment mode longer, and the engine may never reach full operating temperature during short trips in winter. A stuck-closed thermostat is more dangerous, as it can lead to rapid overheating and engine damage.
At Clutch Auto Repair in North Spokane, thermostat replacement is a straightforward repair on most vehicles. We replace the thermostat along with its gasket or O-ring, drain and refill the cooling system with fresh coolant, and bleed any trapped air. We verify proper temperature regulation with a test drive. Call (509) 487-0161 for a quote.
