The temp sensor is on the passenger side of the engine. On the right side of the throttle body look straight down past the hoses you will see a sensor screwed in pointing forward. It has 1 wire going to it and you unscrew it with a 17mm socket.

Hello, your coolant temp sensor is mounted on the cylinder head coolant crossover pipe. If your standing at the front of your car with the hood open, if your looking at the engine the sensor is to the left of the throttle body under the intake manifold. I think it takes the open end of a 19mm wrench to unscrew it. There are 2 sensors back there and it's the larger of the 2.

SOURCE: where is the coolant sensor located?

The Coolant Temperature Sensor is located under hood, center, front engine area, below valve cover, mounted next to water outlet Under hood, center, front engine area, below valve cover, mounted next to water outlet.

REMOVAL & INSTALLATION CAUTION Use extreme care if removing a sender from a vehicle which has been driven recently. The coolant could be extremely hot.

  1. Disconnect the negative battery cable.
  2. Access the thermometer on the intake manifold (1.2L engine), radiator (1.6L, 1.8L, 2.7L engines), or coolant pipe (2.2L, 2.5L and 3.3L engines) and unfasten the wire harness attached.
  3. Loosen the draincock at the lower portion of the radiator and drain enough coolant into a suitable container to bring the level below the thermometer.
  4. Loosen and remove the thermometer. Inspect the threads of the manifold, radiator or pipe, and use a thread chaser to restore the threads if damaged.
  5. If reinstalling the original thermometer, remove sealing gasket and replace with a new one.

To install:
  1. Position thermometer, and new sealing gasket into hole in manifold, radiator or coolant pipe, depending on model, and hand-tighten.
  2. Using an appropriate socket, tighten the thermometer to 2-3 ft. lbs. (3-4 Nm).
  3. Connect the wire harness to the thermometer. Tighten the radiator draincock, if not already done.
  4. Connect the negative battery cable.
  5. Fill the cooling system with coolant and bleed.
