Kia 392203C010 Sensor & G/UNIT-WATE

Always be gentle when moving the ECT sensor or connecting/disconnecting it as any damage done to it will affect the efficiency of the fuel injection system. Preliminary actions are to remove the lead from the negative terminal of the battery and sweet partly discharge the cooling system. On the 2005 and earlier models when using a scanner, the ECT is on the coolant pipe above the thermostat housing cover. Unbolt and remove the air filter housing; then locate the ECT sensor electrical connector and disconnect it; the remaining bolts should be detached to free the mounting section of the sensor from the coolant housing. The process of installation is the opposite to the process of removal, paying extreme attention not to over tighten the mounting bolts to their recommended torque and refilling of the cooling system. On all 2006 through 2010 models the ECT sensor is located on the coolant housing beneath the throttle body, and facing the firewall. Disconnect the air inlet duct and the ECT electrical connector and then open the screws and take the sensor out from housing. Use a little of the liquid sealant on the threads before engaging them, but don't use Teflon tape because it interferes with grounding. Similarly, installation is the mirror process of removal and makes sure that sensor is tightened to the right torque and fill up the cooling system. For the models manufactured from 2011 and onwards, the ECT sensor is mounted to the coolant housing which is located below the throttle body. Disconnect the electrical connection, then take off the air filter housing, the spring clip; finally, take out the sensor from the coolant housing. Then Installation is done in the reverse manner to the above, insisting that the spring clip is well seated and the sensor is locked, thereafter, the cooling system is refilled.

Begin by disconnecting the cable from the negative battery terminal and partially draining the cooling system.
