OEM Thermostat for the 2010-2011 Toyota 4Runner equipped with the 2.7L.
The Coolant Thermostat allows coolant to flow through the engine once it has reached operating temperature. A bad or failing Thermostat will become stuck open or closed. If the thermostat is stuck open, the vehicle may not reach operating temperatures, and if it is stuck closed, the engine can possibly overheat and damage other components.
Ensure optimal function and fitment with this genuine Toyota replacement part.
