Coolant warning light comes on and temps go back to 80
As said in the title the warning light comes on for coolant when it’s at about 90 to 95 degrees then the temperature goes down to 80. I replaced the thermostat thinking that was causing the fault but it’s still happening

Faulty sender/sensor perhaps?

The sensor is built into the thermostat housing so it’s new aswell
