The Toyota Genuine Thermostat is a direct-fit replacement for Toyota Hilux 2.4L Turbo Diesel 4x2 models built from 2022 to 2025. The Brass construction resists coolant additives, heat cycling and pressure fatigue. Replace the cap, thermostat and hoses together on high-kilometre vehicles - they are cheap compared with a head gasket. Pressure rating is 120kPa; running the wrong rating will either boil the coolant or stress the radiator seams. Hose is moulded to the factory shape with the correct bends, clip locations and internal diameter. Opening temperature is 80 degrees Celsius, matching the engine management calibration. Sold new with 12 Months warranty cover and full technical support.
