SOURCE: Coolant Temp Sensor
The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.

Fig. ECT sensor location-3.7L, 4.7L engines.
Back to Top Inspect/Test/Replace Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage.
