I just purchased a 2000 v70xc and went thru the car changing all fluids and giving myself a date for repair and upkeep. I dropped the anti-freeze and filled the system back up, but now the dashboard red warning light with the little fan goes on and stays on......anyone know of a reason why, and how can I get the light to go off....my OBDII shows no codes...all systems pass....the temp needle is at the 3 o'clock position..... and the fan cycles appropriately??????? Any help would be greatly appreciated, can't find anything in my vadis either. A big THANKS up front.

There is a sensor in the bottle that may be stuck or faulty, look in the bottle and move it with a screwdriver, see if it helps.

 

Thanks for the info, pulled bottle and gave it a little shake, I'd rather not be putting tools down in there, if I can help it, everything is fine now.

Hello, If there is gunk in the bottle you can wash it out with a floor cleaner (Spic-&-Span, Mr Clean, etc). A magnetic float rides vertically around an inverted, tube shaped casting which houses the coolant level sensor. If that goes out, it's an easy fix. It unplugs and simply lives in the inverted tube; held in place by a rubber collar. Kira

 

Thanks much, cleaned it out and it is working fine now, thanks for the quick response.
