Really concerned it could f**k up my cooling system.
Any idea what's going on?
Thanks for the help

Do they shutoff automatically after leaving ignition in "ON" position for a while? If they do, this is normal.
The Thermostat opens at 170F and send fluid to radiator. Closes at 160F and just circulates water.
If you are reading 180F, it's at the coolant temp sensor which is in rear water piping. Not temp in radiator.
Your obviously getting power but if doesn't shutoff, then you could have a stuck FAN control relay (easy to check and/or replace) IT gets signal from IPDM and ECU.
If nothing else is acting up, I would defer the IPDM and ECU until you check cheap easy stuff. ( Relay and coolant temp sensor and fan control module)
