It's hard to show on the picture, but the thermostat open right on specs which is 180Β°F. It fits and looks identical to the original part, though it does not have the 'Toyota' logo molded onto the housing. Highly recommended. ### ⭐⭐⭐⭐⭐ Worked well on my Prado 120 1GR-FE *by on Reviewed in Australia 5 August 2023* perfect 84-85 degree idle ### ⭐⭐⭐⭐⭐ An effective replacement, it's Aisin!!! *by on Reviewed in Canada 1 June 2023* This part is better than good it's great.
