Question about 2002 Chevrolet Impala
Need to locate and replace engine coolant sensor
If you are refering to the coolant level sensor (causes low coolant light to turn on), it is located on the radiator near the battery on the passnger side. It is on the radiator tank, just below the radiator cap and the upper connection for the transmission line. Heres a picture of the sensor on my 2002 Impala when I removed the radiator (it's the square thing in the center of the picture):

Usually found either on thermostat housing or close by on the lintake manifold. Usually can be removed with a regular wrench.

It is on the Driver side of engine in between the COP's (Coil on plugs) simply unplug the wire use a 19 or 3/4 deep well socket and unscrew it and put it new one... The whole process should only take 10-15 minutes.

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.
