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.

Subject: Blinking red = light...

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?
