I unfortunately have a 99 Taurus with a partially plugged heater core.
It lets just a little bit of lukewarm air through. Is there a way to
unclog it without removing it? The cooling system has had some sort of
muddy looking substance in it since it was bought new...what is the
purpose of this? Is it some sort of stop-leak or something? Also, what
all would I have to do to switch it back to the regular green
anti-freeze? Is this a common problem with the Taurus? A lady I work
with has a 99 Sable, roughly the same mileage, (79000), and hers has a
similar problem. The door is operating fine, the thermostat is new, so
all it can be is the heater core, right?
the removal and replacement of the heater core...... new heater core
probably cost very little from autozone or advance auto parts.. go to
their web site and give them a try.... the core should come right out
without messing with the removal of the whole dash like the earlier
fords...... i think you just remove a small plastic piece on top of the
heater core and then remove it....
Thanks for the replies everyone! I wound up flushing the entire cooling
system, and just for kicks, I disconnected the hoses from the heater
core, and flushed it out seperately with hot water from a gardenhose. At
first it barely dribbled out, eventually got full flow. It looked like
some sort of sludge from that damn Dex-cool antifreeze. I replaced it
with the tried and true green kind. I guess time will tell if it works
Agreed... what makes this group the most valuable is when the original problem
is described and then the ultimate fix is posted. The interim ideas offered
aren't wasted though... they're just more possibilities to consider.
I'm hoping that if anyone else has a Taurus heater problem, what I did
would work for them too. I was definately not wanting to have to go
through the hell to replace the core. Being how this is the wifes car,
every little squeak and rattle would have been MY FAULT! lol

I thought coolant circulated through the heater core all the time. Seems
like if it was clogged up, then the car would have eventually overheated
due to constricted coolant flow.
While I have mine in the shop for them to figure out why I suddenly lost
overdrive, I'm having them check to see why the heater isn't working, too.
Well it DOES circulate all the time, the hot side comes off on the engine
side of the thermostat.
But that doesnt mean anything particularly in regard to the radiator as they
are "parallel circuits".
YOu're right in that a sludgy heater core would signal possible problems
later ... I'd bet the radiator needs attention too. However there's a good
chance that the rad has larger passages than the heater core.
I'm hoping that all the flushing took care of the radiator as well. I
ran it for quite some time with Prestone radiator super cleaner in it,
and let it flush for a long time. I also got that orange crap out of my
2000 Cavalier. It looks to be a major pita to change the heater core in
it, too. I sure do love my old Ford trucks...they are both 1978's, and
the cores can be changed in well less than an hour in them.
It looks like I get to do it all over again! GRRRRR!!!!!!!!!! The wife
came home last night, said it was blowing cold again...I have heard of a
bypass tube.....reckon if I got rid of that it would help? Damn

I had mine in to have some work done to see why overdrive was out and had
them check to see why my heater wasn't working. Clogged heater core here,
too. It's going to cost $427 to have it replaced. He's giving me a deal
on the labor by cutting off 3.5 hours.
I've decided to bite the bullet and get rid of this Taurus. As of
Saturday, I'll be trading it in on an '05 Impala SS. Maybe the wife will
let me borrow it sometime! After seeing all the Taurus problems,all over
the internet, I just do not want to go through a lot of junk all the
time. I do not mind working on the old stuff, but the new ones can be a
headache for me. The wife traded in a perfectly good Cavalier for this
Taurus, and it gave her 172,000 miles of, for the most part, troublefree

Well, my plan is to keep my Sable running, even to the point of replacing
the engine. I was tempted to buy a new Ford F-150, but I almost have the
Sable paid off. I want at least a couple of years of life without a car
payment. And I want to see if its actually cheaper to just keep replacing
the engine and transmission when needed. I'm up to 169,000 miles now and I
have had a lot of work done on it. It still runs as smooth as silky
I did buy this thing used and actually, I would like to start with a
brand-spanking new one so I can be sure it's taken care of properly for
maximum longevity. I don't know how my current car was treated for the
first 88,000 miles of its life. But it appears that I'll be putting about
50,000 miles per year on it. If the engine and transmission hold out for
300,000 miles, that'll be great. Maybe replace those once, then replace
the whole car the next time around. :-) It'd be great to look down and see
600,000 miles on the odometer. :-)
