no just lower the level or be quick about plugging in the new sensor, that is what I do, u may lose a cup of coolant but much less hassle than draining the radiator.

2.2L Engine

NOTE Use care when handling the coolant sensor. Damage to the coolant sensor will affect the operation of the fuel control system.

  1. Turn OFF the ignition.
  2. Drain the coolant system.
  3. Disconnect the Engine Coolant Temperature (ECT) sensor electrical connector.
  4. Carefully back out the ECT sensor.


Fig. Coolant temperature sensor for the 2.2L Engine

To install:

  1. Coat the threads only with sealer P/N 9985253 or an equivalent.
    NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  2. Install the ECT sensor and tighten the ECT sensor to 18.5 ft. lbs. (25 Nm).
  3. Connect the ECT sensor electrical connector.
  4. Refill the engine coolant system.
