Kia 3922038010 Sensor Assembly-Water Temperature

Handle the ECT sensor with care. Damage to the ECT sensor will affect the operation of the entire fuel injection system. Note: The ECT sensor is located at the left (driver's) end of the engine, on or near the thermostat housing. Disconnect the cable from the negative battery terminal. Partially drain the cooling system. Disconnect the electrical connector from the ECT sensor. Unscrew the ECT sensor from the coolant passage. Don't seal the threads of the new ECT sensor with Teflon tape, as this will interfere with the grounding of the sensor. Apply a small amount of liquid sealer to the threads before installation. Installation is the reverse of removal. Be sure to tighten the ECT sensor securely. Refill the cooling system.

Avoid sealing the threads of the new sensor with Teflon tape, as it will interfere with grounding.

Drain the coolant, disconnect the electrical connector for the sending unit, using a deep socket or a wrench, remove the sending unit, install the new sending unit, and tighten it securely, connect the electrical connector, refill the cooling system and check for coolant leakage and proper gauge operation.
