You will need to trim some of the fiberglass in the area of the temp sensor to gain access. Be advised that if you connect the two wires on the temp sensor together, the fans will run. A good test before replacing the part. You can get a new sensor from NAPA Autoparts, just be careful of the temperature operation range (ON/OFF) of the sensor you purchase. I use a sensor that runs a bit cooler the the stock sensor. I purchased it online from Automotion which is a Porsche parts company. Look in their Porsche 924 area (It's a water cooled Porsche) to fine the sensor.
Needed to purchase a few different sockets to remove and reinstall the part. As I recall a 3-4" drive deep well socket was too deep and a standard socket was too short because of the two electrical connectors on the outside of the temp sensor. Needed to bend both the electrical connectors a little to fit into the area wher the 3/4" drive socket fits into the socket. So you can't fully engage the drive socket into the socket when loostening of tightening the part... Hope that make sence. Once you have the parts in your hand it will all become clear.
Are you having fan problems? There is also a relay in the fans electrical circuit. Describe you problem before replacing the part if you like.
