Flashpower thermostat for the LS Gen IV 5.3/6.0/6.2 (2007-2017). Listed for one application: LS Gen IV 5.3/6.0/6.2 engines, 2007-2017, in Chevrolet, GMC, Cadillac, Pontiac applications. Confirm your engine code and year against this listing before ordering.
What it does
The thermostat controls when coolant flows to the radiator and sets operating temperature. Stuck closed it overheats the engine; stuck open it never warms up, hurting mileage and setting a P0128. A new thermostat at the correct rating restores stable temperature.
