Steps
Let the engine cool and drain coolant
Work only with a fully cooled engine. Place a drain pan under the radiator, open the drain, and capture coolant; close the drain once the level is below the sensor.
Remove the old sensor
Remove the lower splash shield and unplug the sensor connector. Remove the 17mm retaining fastener and withdraw the sensor from its mounting point.
Install the replacement sensor
Position the new sensor and install its retaining fastener to the vehicle's specification. Reconnect the electrical plug and route its wiring away from hot or moving parts.
Refill and bleed coolant
Reinstall the splash shield and refill the radiator with the correct coolant. Follow the vehicle's bleeding procedure, setting the heater controls as directed and monitoring coolant level as air escapes.
Cool and check the system
Shut the engine off and allow it to cool fully before replacing the radiator cap. Check the overflow bottle level and inspect the sensor and drain for leaks.
Check your vehicle’s repair manual for exact specifications and fit.
