How much should it cost to replace a temperature sensor in a 1999 Saturn ls?
Depending on the labor rate of the shop, altogether costs for repair should be $125 or less. The coolant temp. sensor itself is around $20 and the labor guide calls for 1.1 hours of labor.

I'm not looking at the unit. Are special tools required?

 

Should not require any special tools, installation is straightforward. Here are the instructions.

NOTE: There is only one temperature sensor used for all coolant temperature readings the ECT sensor. The PCM uses this sensor to operate the temperature gage in the instrument cluster, illuminate the hot/low coolant lamp and for air/fuel control. This sensor is a two wire sensor.

REMOVAL

  1. Turn ignition Off. NOTE: Engine coolant must be drained below level of engine coolant temperature sensor before removal.
  2. Disconnect electrical connector from engine coolant temperature sensor. NOTE: The connector must be removed by squeezing the sides. Apply pressure to sides of connector gently with pliers. Do not pull on wires.
  3. Remove engine coolant temperature sensor using a deep well socket.

INSTALLATION

NOTE: Tap out sensor mounting hole in engine to remove any thread sealant residue. Clean any thread sealant from sensor threads and coat sensor with correct thread sealant if installing the same sensor.

  1. Apply thread sealant Saturn P/N 21485277 (Loctite 242 Threadlocker or equivalent) to sensor threads.
  2. Install engine coolant temperature sensor. - Torque: 8 NM (71 in. lbs)
  3. Connect electrical connector to the engine coolant temperature sensor. Push in until a click is heard and pull back to confirm a positive engagement.
