The temperature gauge just started going into red then I let off the accelerator an turned the hot air up an it goes down then some times it's fine others the air only helps keep it out the redzone but the gauge is going up an down when I hit the gas or let off

    Restricted water and/or air flow at the radiator. Have cooling system checked before engine problems are caused.
