1987 RX-7 add coolent light on and buzzer when stoped

my RX-7 buzzer for add coolent goes on and i already checked the level and seems to be fine as well as the sensor but it only goes on when im stopped once i start going it stops someone help me please...

connection may be loose. If your cooling system is okay its probably the sensor or the wiring to it.

mine went off all the time while driving, it was annoying as hell. coolant levels were fine. i grounded out the wire, but now im risking it. everything is new on my car, so i think ill b ok, but i still need to get it fixed soon.

you may have an air bubble in the system. Try unscrewing the air bleed screw on the upper radiator neck above the thermostat, and make sure that the coolant is full there.

thanks, ill check that out sometime, vehicle sitting in garage for now anyway..
