Dash Pod Lights???

I own a GDE 1991 Range Rover and noticed an interesting light flashing on my home from work today. It flashed red and the picture looked like the radiator. I checked the coolant fluid level which was a little low and added soem coolant to see if that solved the problem, but alas the problem persisted till I got home. The light is on the bottom row of warning lights on the far right, lower corner. Please help!
Thanks
