have a 1998 ford taurus with no heat,I changed water pump and thermostat but didn't help, I was told to change the heater core and I even bought the core but couldn't figure out how to take the core out.looks like the whole dash has to come out, if anyone has any idea please reply. Thanks

I don't know how to change it in a taurus, but did you check that your blend door was functioning properly?
Here is a basic explanation of how the heating system works.

The way that they say to change out your heater core is to remove the entire dash and steering column on said vehicle...it's a 7.5 hour labor intensive job that ford will do for anywhere from 600-900 dollars not a job for someone who does not have the proper tools and experience to tackle.

Ford also has a way to power flush the system with an acid that I was told by a ford dealership that they seem to have pretty good results with...you may want to inquire about that, I was told it costs around $160 -$200

time-saving on heater core replacement

This is what I found spulunking around the net, I have not tried this proceedure yet and you may do so at your own risk...GOOD LUCK!

clamp off and disconnect the heater hoses (and plug the heater core necks), of course. Remove the ashtray and its bracket (four 7 mm screws accessed from behind). You can take out the glovebox if you think it will help, Remove the side covers of the dashboard, which gives you access to remove two 13 mm bolts at each side of the dash. With the ash tray and bracket out, work through the opening. On many models you only have to remove the temperature (blend-air) door motor for access to the heater core access cover On others, there may be some things in the way. If the car has Electronic Automatic Temperature Control, there’s the EATC remote module. Disconnect the EATC remote module wiring connector and vacuum harness, then remove the module mounting screws and finally the module itself. There may also be a secondary A/C temperature (blend-air) door in the HVAC case, with an external connecting metal link and spring, etc., covered by a little metal shield, at the heater core cover. Start by removing the shield, then unhook a spring from the heater core cover, gently disconnect the metal link at both ends, and rotate the temperature door pivot shaft (plastic, so be careful) out of the way. Remove the retaining screws for the heater core access cover and take out that cover Remove the top cover on the dashboard (close to the defrost openings) – it’s held by spring clips. With this cover off, remove the three 8 mm bolts in the cover opening. Have a helper assist you to gently pull back and support the dash (helper on the driver’s side, while you work on the passenger’s side). You’ll be able to get enough clearance to remove the old heater core. As the helper still supports the dashboard, reverse the procedure to install the new heater core, gently realign the dashboard and reinstall all the fasteners. Sorry, but this won’t work on pre-1996 Taurus/Sable models.
