AISIN manufactures it for exact OE form, fit and function to help maintain cooling-system performance.
- Construction: brass and stainless steel.
- Start-to-open temperature: 82°C (179.6°F), holding coolant within its intended temperature range.
- Jiggle pin check valve: included, which helps bleed trapped air from the housing.
- Gasket/seal: included for a fresh seal at install.
The thermostat stays closed during warm-up to speed the engine to operating temperature, then opens at its rated temperature to route coolant to the radiator. Signs it may need replacing include overheating, an engine that runs cold, or a fluctuating temperature gauge. If a stuck thermostat is the cause of those symptoms, this assembly replaces it. Country of origin: Japan.
