Your thermostat is stuck in the open position. Replace the thermostat and no more problems. Quick fix and only costs about 20 dollars.
Under 20 dollars just make sure you have the right information as you will get wrong thermostat, and is very easy to change out. under radiator cap is where the thermostat is located and there are 2 bolts that hold it in.
