He CL gurus. My radiator light has been coming on the last couple of days when I start my car and turns off after 5 min of driving. The radiator is brand new. Its a Koyo stock replacement. Its filled with Toyota /Lexus coolant. Any ideas on what could be causing this light to come on??

Is the overflow tank filled? If it's new, it probably burped out some air after driving a bit.

Thanks for the info. I will check the overflow tank again. The light seems to only come on when the engine is cold and a few intermittent times on the freeway. Is there a sensor that could be going bad? If so do you know where it might be located.
