Should i be worry that my coolant light goes on even before I start the engine? There's no signs of leakage and it's been like this for months now, although i only drive the Rx7 on weekends. Any feedback would be great. Thanks in advance.

 

does the light go on and turn off, or does it make a sound and stay on?

 

the light does make that buzzing sound, although after driving the car for a couple of minutes or so; the light and the sound will eventually stop. However, it comes back on everytime i start the car again, and the whole process begins once again.

 

I would check the wiring to the sensor, or try replacing the sensor itself. It is designed to go off when the circuit is open, so if you have a loose connection that will cause it to go off. A long time ago I had it act up on me, the buzzer started and stopped while the key was still in the ACC position before starting the car, but it only happened once and never came back, so I didn't do anything. Also make sure you don't have air in the system and that you have the coolant topped off (obviously). If it still goes off even with coolant topped off, while the car is off, then it almost definitely is the sensor or wiring.
