Google 2006 Saturn ion thermostat replacement. The link won't paste for some reason

there is a switch in the coolant tank ,could be stock or defect

your battery maybe weak or the terminals of your battery are loose. check your battery charge and clean and tighten your battery terminals.

This sounds like a reset problem. Possibly the ignition interlock ( Just another word for Factory reset code needed for your computer.) Usually the little padlock symbol will be on in dash. Removal of the battery could and usually will fool the computer into thinking the car is being hot wired into starting.

you need to buy a new one . remove the screws. remove the broken one and reinstall the new one....seriously

I don't know where you live I lived in CA when I bought my Saturn and when that light came on in my Vue it was an emissions light had a small pin hole in one of the lines for the emissions

Possibly loose or dirty battery connection

Sounds like a controller concern.Most likey ECM located under hood near battery.has to be programmed when replaced.hope this helps
