    Default 2000 Taurus No Heat

    Not getting heat from the vehicle (used to work fine)
    Have already flushed coolant system and replaced thermostat.

    Anyone with experience or real knowledge of this problem please help.
    Links to places with good info also appreciated.

    TIA

    To add to the above when the defroster is used it also does not put out
    any heat.

    Does the water temperature on your temperature gauge rise?

    It may be that the heater core or hoses going to the heater core are
    blocked.

    If the engine warms up OK, it's probably the blend door actuator that
    has gone bad. but if you have climate control, it could be the ATC
    control unit. The owner's manual usually has the self test for the ATC
    in it, and it's also available many places online.

    It's possible your water pump looks like this:

    when it should look like this:

    I thought they had this problem licked by 2000, but your car may have
    had another issue resulting in the water pump failure.

    I thought the water pump issues were mainly with the 2.5L version in the
    Contour/Mystique (the plastic impeller would crack and not spin with the
    shaft, or come lose and shatter.)

    Those pics are NOT of a plastic rotor! It is METAL eroded by
    cavitation. This is a Vulcan issue, the 2.5 is a Duratech.

    A friend who worked at the local Ford dealer, said it was delt with,
    but not enough.. there was supposed to be some kind of sealer, which
    would prevent the erosion from happening..

    Contrary to someone else's remark, of it being cavitation, hardly..
    Cavitation is caused by a
    lack of water, and a vaccume is caused, by the water beginning to
    actually boil, til it
    suddenly gets a brief amount to lower the vaccume, where it litterally
    hammers the entire
    system. (firefighter, same thing happens if running a pump too hard,
    without enough water
    through the hoses to supply.. Blown quite a few steamer caps (main
    inlet caps) off trucks,
    and masacured too many impellers that way.)

    the true cause, is the dissimilar metals, and electrolytic action. add
    the cast iron block & heads, add a aluminum pump chamber, and a mild
    steel impeller just sitting in the middle. the result, the slight
    acidity to the antifreeze etches the mild steel.

    I ran into the exact same problem, with a 1999 vulcan (3.0 V6 OHV) and
    it cost me dearly, to get it back roadworthy again. (2 sets of head
    gaskets, new pump, new radiator, machining to the read head to
    eliminate warpage, serpintine belt) Mine didn't look as bad as the 1st
    photo (image002.jpg), it still had the points left, but resembled a
    martial arts throwing star.

    the friend said they were coming in, in waves once the problem
    appeared.. All they could do, was replace the pump, and whatever
    damage, and send them on, till the sealant was used.. but even that
    wouldn't stay. (rust on the block internals, it couldn't adhear.)

    Yes, the problem was partially electrolysis and corrosion but cavitation as well.
    Cavitation in the cooling system is well known to folks who deal with diesel engines.
    The theory is exactly as you describe but on a much smaller (molecular) scale. The
    combustion pulses cause micropulses in the cooling system along with harmonics of
    those micropulses. This causes the coolant molecules to separate into gas that tends
    to coat the hot internal surfaces of the engine. Vibrations shake the bubbles loose
    allowing contact with liquid which causes rapid cooling of that tiny area. These areas
    eventually erode. Impurities then leach out of the eroded metal and cause corrosion in
    the cooling system. They also cause the PH in the coolant to become acidic, leading to
    severe electrolysis and erosion of the water pump impeller.

    If your "friend" is a Ford tech and has been properly briefed on this "concern", he
    SHOULD know this. (BTW, In Ford speak, a problem is only a "problem" if they have a
    fix. Until then, it's a "concern")They "came in waves" in about 1999-2003. There was
    NO SEALER EVER INVOLVED in the Brown Coolant recall or recommended afterward. The
    pumps weren't replaced, as a rule, either.
    I did MANY "Brown Coolant" recalls on Tauri at the dealer during this period. The
    systems were flushed with a highly alkalne solution, flushed, and the proper mix of
    ethylene glycol added. There were also bypass hoses added to the cooling system to
    alleviate the cavitation. I always thought that the water pump and core plugs should
    have been replaced on all of those vehicles. They have been an area of concern since
    then on used Tauri.
