it does not look very hard to replace the sensor....just unclip the lead (***after the engine has cooled, of course), unscrew the sensor and install a new one. They say use a new copper gasket too...sometimes just disconnecting the clip, checking that the contacts are clean and reinstalling the clip can get a sensor working again, but its a long shot.

guys, will any coolant leak out when the sensor is unscrewed?

just wondering.
