Removal & Installation

Print

  1. Drain the cooling system to a level below the ECT sensor.
  2.  
  3. Unplug the harness connector from the ECT sensor.
  4.  
  5. Remove the ECT sensor from the engine.
  6.  
  7. Installation is the reverse of removal. If reusing the old sensor, coat the threads with GM sealant 12346004 or equivalent. New sensors are already coated; additional sealant is not needed. Tighten the sensor to 16 ft. lbs. (22 Nm) on 3.6L engines or 15 ft. lbs. (20 Nm) on 4.6L engines.

CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Turn the ignition OFF .
  4.  
  5. Remove the coolant temperature sensor electrical connector.
