    Q:
    How to Replace a Coolant Temperature Sensor on a Honda Crosstour? Posted by Customer
    A:
    Drain the engine coolant, remove the air filter housing, and disconnect the electrical connector from the ECT sensor. Unscrew and remove the ECT sensor and remove and discard the old O-ring. Tighten the ECT sensor to the correct torque, refill the cooling system, raise the vehicle, and support it securely on jackstands. Remove the lower splash shield, unplug the electrical connector, and untighten the sensor from the radiator. To reinstall, switch the removal steps going from the final step to the beginning step. Install a new O-ring on the sensor, tighten the ECT sensor securely, and refill the cooling system.

    Q:
    How to replace the Coolant Temperature Sensor on a Honda Fit? Posted by Customer
    A:
    There are two ECT sensors, the first is located in the cylinder head, facing the firewall, towards the driver's side of the engine, while the second is found at the right end of the lower radiator tank. Begin by draining the coolant from the engine. For the first sensor, remove the air filter housing, and if working on a 2009 or later model, take out the bolt securing the hose bracket at the left end of the cylinder head and move the hose aside for access. Disconnect the electrical connector from the first ECT sensor, then unscrew it from the cylinder head. Installation involves reversing the removal steps, ensuring a new O-ring is used and the sensor is tightened to the specified torque. Afterward, refill the cooling system. For the second sensor, raise the vehicle and support it securely on jackstands, then disconnect the electrical connector from the sensor located in the radiator lower tank. Unscrew the sensor from the radiator tank, and similarly, installation is the reverse of removal, using a new O-ring and tightening to the specified torque before refilling the cooling system.
