Recently, my low coolant light will sometimes come on right after I start the car, but will go away after a little bit. After it goes away, it doesn't come back on ever and the temperature gauge and stuff acts normal. I checked and have plenty of coolant. What should I be looking at or is this possibly something as simple as air bubbles in the system? Just don't feel like blowing up the motor.

Thanks.

 

Its probally a little low, or got a small amount of air in it... Whats happening is when you start it, whats in the radiator is a little low, when you get the car up to the temp the thermostat opens and starts throwing water back in there, so the senosr is covered enough to keep the light off

Take the radiator cap off when its cold, start the car up and right as the thermostat opnes a little bit add water/antifreeze solution until its full. Then put the cap back on, maybe you will get the air out like that..

 

i had the same problem when i first got my rx, mike's idea should fix it.
