ok, my check engine coolant light came on, so i checked fluid levels and it was fine, so i thought maybe it could be just a short for the check light, but then i opened the radiator cap when it cooled down, and i saw what looked like a little bit of rust in the tube that goes to the recovery tank, so is it possible that theres sediment in the tube thats keeping the fluid from going to the recovery tank? also i drove the car around for about a hour paying close attention to the temperatures, and the coolant gauge didnt go to dangerous levels.. so whats yalls opinion on this, should i take it in to be looked at?

 

If it was the "Low coolant" light, don't worry about it. They are notorious for going bad. Most people just uplug it.
