there are seven bolts in the dash, but have to take 2 bolts out that hold the fuse box plus 4 nuts that hold the steering column up and you can pull back the dash enough to get at the heater box and there 3 or 4 bolts that hold it in. then you can see 4 bolts on top of the heater core housing that you can take out. oh don't for get to disconnect the a/c hoses on the firewall and the bracket there are 2 nuts be careful. i did my wife's heater core in her 87 t-bird last week. if need pictures i have them okay at robdean2@hotmail.com
in order to remove a heater core, you must take apart the whole dash. when i tookout my heater core in my cougar i had a hard time and i cut the dash and later on i founf out that you take it all apart. that's all i know. Dustin from pa
What helped me the most was this website, it practically walked me through every step. Be careful with the dash, mine was very fragile and i came close to cracking it many times in this process. good luck! http://www.turbotbird.com/techinfo/Heater_Core/heater_core_replacement.htm

Begin by removing the water supply hoses from your 1989 Chevy heater core. Remove the heater core retaining bolts. The heater core can be removed.
The water from your 1989 Chevrolet Cavalier cooling system. Remove the heater core water supply hoses. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
you might be able to just go through the back of the glovebox to get to the heater core
you have to remove the dash, get a Haynes manual Chilton's may be better rent from library) follow the remove dash instructions, heater core is slightly to the left of the glove box. remove heater core cover, remove hoses from heater core (engine compartment) pull out old core. pia job.
First remove the dashboard to access the heater box and core! Then reversal of strip down to rebuild.
The 1989 Chevrolet heater core can be found behind the kick plate. You will need to remove the passenger side kick plate in order to access the heater core.
No................... Its located in the center of the vehicle but you will need to remove the side panels if equipped and then remove the lower heater core cover and the heater hoses.............
much more difficult. Ford usually install the dash as a unit and the heater core goes in from the front. If you have nerve enough, remove the glovebox and you should be able to see the bulge where the heater core is. Cover should be plastic, carefully cut the housing big enough to remove the core, remove it, reinstall. Can be done, just takes a little time and effort. Not as much as doing it the "right" way. <2008-04-18> Agreed. Would suggest Bar's Leaks or just bypassing the heater core. I live in Florida, heater core has two uses -- (1) to "warm up" the cold AC, mine is VERY cold without the heater core, to where I have to periodically cycle the compressor. (2) to heat the defroster air. Without a heater core, the cold air on defrost winds up counter productive.
behind the dash....
Disconnect the negative battery cable and drain the cooling system.Disconnect the heater hoses from the heater core inlet and outlet connections in the engine compartment.Allowing residual coolant from the heater core to drain. Cap the openings.Working inside the vehicle, remove the lower instrument panel sound insulator.Remove the heater floor outlet duct screws or clips and remove the duct.Remove the heater core cover by removing the attaching screws and clips.Remove the heater core cover.Remove the heater core retainers and remove the heater core.
