Q: My temp gage barly goes past 130

asked by on

Today i was driving around town n i noticed that my temp gage was barly off of 130 n it should have been at operating temp by that time. Im thinkin it might the thermostat stuck open. But im not sure the truck did sit n barly drove for last few years up intill the last 6 months after i took it over from my dad. Maybe just need a good radiator flush not sure.
My car has an automatic transmission.
