If overflow tank empty, then when coolant contracts, air gets into system.  Air in system = blinking red light.  Probably need to drain and refill cooling system.  See archives or Bentley for instructions.

  Hi all gurus,
  I have this '85 van and the coolant light started to blink.  I never use the car really.
  The overflow tank is empty, but the expansion tank is full.  It happened after I had the A/C guy out here.  I think there is no connection.  What is the remedy or the solution to this?  Anyone?
  Zoltan
