    I have a 2001 S80 T6. I haven't seen any coolant messages so can't help
    there. The fan blower operation is a normal event and not temperature
    related. It comes on an hour after shutdown and runs for a period of time
    to dry any condensation in the A/C system.

    I had to replace the original battery about 4 months ago. That is the only
    time the car would not start.

    Well, you have to love volvo, they have to get the award for over
    engineering every last detail, the same reason I love my care is the
    same reason it scares me... they do not follow the K.I.S.S. thoery of
    auto design... I mean come on, drying out the condesation in the AC
    unit? Isn't that a little over zealous?

    I think Roadie is on the right track. Dunno about the S80, but most cars
    with a "low coolant" indicator are telling you the level in the reservoir is
    low. Those sensors fail fairly often, but be sure the level is right.

    Hey mike, thanks for the follow up, I'm going to try to add coolant,
    it is hovering at the minimum line...

    You'd think so, but... in the early '90s, following changeover from R12 to
    R134a and the redesign of the AC system that involved, several automakers
    had a rash of evaporator failures. The early 850s were hit especially hard.
    Mysterious pinholes would form in the evaporators after only a year or two
    and a very expensive repair followed. The problem was traced to corrosive
    mud that formed when dust and pollen collected in the condensation on the
    surface of the evaporator. The first fix, one that was widely adopted, was
    the addition of cabin air filters. It helped a lot but must not have been
    quite enough. Volvo and Honda (also badly affected by evaporator failures)
    have now programmed the HVAC fan to dry out the evaporator after use. Other
    makers may be doing that, too.

    I confess I'm bewildered by the various types of antifreeze in use now. The
    safe thing to do is to add a pint or so of distilled water. It's compatible
    with any coolant! Eventually somebody here will have the full answer, but
    the water is a good start.

    Thanks for the response,

    I was waiting to see what was going to happen after a few mornings of
    cold starts. I have added some coolant to the car and since the error
    message of Coolant Low, Stop Engine or Coolant Low, Stop Safely has
    stopped coming up. Nonetheless, I am going to have the car inspected
    to verify that there are no small leaks that might cause future issues
    down the road. Thanks so much for you expertise and opinions!
