98 Explorer temp sensor question

[sobo]

Hi Guys,
I have a 98 Eddie Bauer v6 sohc and have a leak on top of my thermostat housing. I replaced the coolant temp sensor and the thermostat which took care of most of the problem but still have a slight leak. The temp sensor is closest to the driver side but what is the sensor closest to passenger side? When searching auto stores I only see the coolant temp sensor?
Thanks

You have a SENSOR and a SENDER. The sensor give coolant temp info to the ECU, the sender works the coolant temp gauge in the instrument cluster.

Often the screw-in type sender/sensor will cause leaks in the upper t-stat housing if they are disturbed. Later models used sender/sensor that push-in, are sealed with an O-ring and have a clip that holds them in place. You may need to replace the upper t-stat housing to stop your leak. You can upgrade to the newer style housing, but you'll need to buy the newer style sender and sensor.

Ditto. Don't know if you want to upgrade the lower thermostat housing after replacing the sensor.
Threaded brass inserts are leaking and new original lower or RH144 upgraded housing is needed.
