Coolant Temp Sensor

Hello,
I have a 98 5.9, and the other day the message came up that my coolant temp sensor is bad. And it looks like they are no longer available. As of right now I am not getting the message again. I would like to be ready for when I do need to replace & asking what do I use?
Any input would be great!
Thanks,
Glenn-

Coolant sensor bad refers to the level sensor in the overflow bottle, not a temp sensor.

Hello,
Thanks for the reply. I will check the sensor in the coolant tank. So are the 2 sensors on the radiator hose's for the electric fans?
Thanks again !

Yep, the sensors in the radiator hoses are for the fan. The upper hose sensor is for low speed, the lower hose sensor is for high speed.

Its not a TEMP Sensor.

Its a LEVEL sensor. Its in the coolant overflow tank.
