Q: Fluctuating coolant readings
I have been getting a fluctuating reading on my coolant recently. My dashboard sensors are going from normal to 260 and back down. It goes up and down in readings the entire time I am driving. I changed the coolant, temperature sensors and thermometer. I didn't use a torque wrench to do this with. The problem still persists. Do you know what is going on? My engine seems to be a normal temperature.
