I have a 2000 Saturn and my temperture gage after it warms up reads normal, but when I drive down the road every so often it fluctuates down to cold then back up to normal. Could my water pump be going bad or would it just be the thermostat

Sound's like a bad coolant temp sensor i posted a diagram of where it is.Make sure the engine is cold when you change it you will loose coolant.All so make sure you get a brass tipped one the plastic tipped one's crack.There only like 10 when you change it make sure you inspect the connector if it's corroded you have to change the connector as well.Let me know how it goes.
