Why do you think you need to replace the engine coolant temperature sensor?

You can go to www.autozone.com, click on the "repair guides" link and
navigate to the repair guide for your car and look under "engine cooling"
section for the procedure for removing, testing, and replacing the engine
coolant temperature sensor. The sensor is located under the exhaust
manifold, which has to come off if you replace the sensor.

If you are trying to fix a P0125 trouble code, replacing the engine coolant
temperature sensor will not do the trick. If you are trying to fix the
P0125, check the O2 sensor that is mounted in the exhaust manifold. The
procedure for checking the O2 sensor should also be in the autozone on-line
manual.

Let us know if you have any questions. Are you a Wolf hockey player or fan?
