Temp Light Flashes While Driving

:screwy: Hello All, I have a 1998 Pont. Trans Sport 3.4 v6. While driving the temp. light blinks/ flashes on for 3 sec. off then blinks again. The gage on the dash is reading low about 120 deg. Any Ideas? TKS:rofl:

It either indicates "Low Coolant" level



or a loose connection ? ;)

Now it stays on all the time andgage on dash does not move. Top radiator hose is HOT and bottom is barely warm? help
