I checked for anything leaking flushed my system out and back flushed my system out I have replaced the radiator waterpump pressure cap thermostats and thermostats switch about a year ago so all is fairly new but as soon as I turn my engine on it almost automactically reads its overheating any one with any help on this? ??

Have you changed the sensor for the temperature gauge?

[Girlfixinhertruck]

No but I will try that in the morning thanks

[Daryl Z71]

Let us know if it changes anything. It seems like there's a problem with your gauge which leads me to believe it could be the sensor.

Thank you and I will!
