Message:
Ok, so my heater core went out, and i have the replacement part. But looking at the chiltons, it says that i need to remove the ac accumulator. Which means that i need to remove the freeon. Is there anyway to get around this??
how high of a dollar amount am i looking at to have someone do it for me?
thanks guys!

Xphile,
On my 00 the dash gets unhooked and just about removed from the firewall. Haven't read that chapter too close in the book. So I'd say "yea " ya need to discharge the A/c. Have the "pro" do it. The whole job will wear you down. My $.02. C YA

Mine went out earlier today. Antifreeze everywhere. Anyway, I have a 2000 and it seems that many people have this problem before putting too many miles into it. Is there some recall I could look at, or is this covered by warranty somewhere? The dealer is telling me it wil cost almost $500 for this crap and the truck is 2 years old and has 45k miles on it. Just paid that thing off 3 weeks ago. Also, I read somewhere a few minutes ago that it could be a seperation clip, not the core, that breaks and causes hoses to rub and wear down, slowly but surely, eventually rupturing but in the meantime giving the signals of a bad heater core. That's as easier and cheaper fix. But, I want more than just my own opinion before looking at it that way. Thanks.

i just put a heater core in my 97 3.9, and to say the least it was a pain in the ass. it took about 12 hours to do, and no you don't have to drain your a/c, at least with the 97's you don't. Let me just say, it is good to have a family member who owns a garage as a business, or else i would be broke. There is no easy way to do it. You have to drop the steering column, and roll your entire dash back onto your seats..yee haw, and after that you still can't get to the heater core, you have to break into the fort knox of an airbox that the genius's at dodge thought up, and then when you do get to it getting it out of the hole it is in. i think they built the truck around the heater core. as a matter of a fact i think that whoever thought of putting the heater core where they put it should be beaten severely. Ok i feel better having gotten all this out. Anyone put one in lately i would love to hear your opinion.

I can guarentee you it will be a pain in the a$$. I did mine on a 95 3.9 and you have to discharge the A/C, pretty much take everything out of the cab except maybe for the seats, and then your about a 1/3 of the way there. You still have to negotiate getting the air box out, take it apart, replace the core, and have fun sealing the box back up...I found that to be extra special fun. But not as much fun as trying put all that $hit back together. My radio hasn't worked in 2 years.

My 98 CC SLT dak had to have the core replaced just three weeks after I bought it brand new in September of 97. Warranty covered everything but they had my truck for two weeks.

Sam i did the heater core on my 98 and did not have to do anything with the freeon, i'm not sure how much difference your 2000 would be but i had to pull the dashboard off to get to the heater core and yes it was a job that i would prefer never to have to do again, so i'm pretty sure to have it done for you will cost a pretty penny, my heater core was buried in a box deep inside the dash board and the coolant lines were the only thing i had to disconnect from what i recall....its been a few years.

My 2000 Dakota 6 cyl heater core is leaking. I have the dash completely out, next is the heater/ac box. How do I disconnect the ac lines?
I took the "u" shaped clip off each line, however the lines would not separate.

A special tool is needed to disconnect them. Your local A/Z should have them for rent. Don't forget to evacuate the system before disconnecting the lines.

Just did the heater core in my ( 1997 )truck also. It was 3 days off and on to get it out, one day to put it back together.
You need to disconnect the accumulator, which is a pain in itself, since you have to get the disconnect tool onto the two fittings which are up against the firewall.
the heater core in these trucks is indeed built not for our beloved Daks, but for the 1987 Dodge Omni, if you can believe that...thank you engineers for building the truck around the core!
As far as removing everything to get it out, a few pointers. Yes, the steering column has to be removed, but only the four screws that hold it in place ( they have funky looking washers that help lock the bolts ) You need to disconnect the brace on top of the hump and remove it. You need to disconnect all the screws holding the wiring loom and loosen the fuse box.
It looks like this when the dash is out ( I removed mine for easy access..don't forget those ground straps! ) http://lh3.ggpht.com/_pf6aWNx1mbk/TDf3NhfNPFI/AAAAAAAADDE/U2BB3r4-Kc4/100_2444.jpg
If you are willing to attempt pulling the dash, then you can do the job..most of this job is pure will power. I did mine at night with the mosquito's biting.
Be methodical, and you don't have to remove anything off the dash other than the fascia around the gauges/radio and the glove box. You can leave the screws for the dash cover alone.
Also, the controls for the blend door selector..the vacuum lines....they can be disconnected at a fitting once you've pulled the dash partway out, there is a fitting halfway that you can disconnect easily.
As far as the A/C goes though, if it's charged, get it discharged professionally, otherwise you risk hurting yourself ( I give less than a damn about the environment, I'm more concerned about the guy working on the truck ).

Ya redfury is right. Ac thing exploded in my face last time I
disconnected them. It left me deaf for about two days.
Anyways...
Here's a list of all the things that need to come off.
First unplug the two sensors u der the steering wheel, then
there's a white box next to the brake pedal and disconnect
those three sensors, then parking brake connector.
Then ya need to unscrew the knee holster thing and then
unscrew that metal piece connected to the sensors for smog
checks. Then ya need to take off the white screw connected
to your transmission thing on your dash that says if you are in
drive and parking neutral and ya know. Then disconnect the
hood realease thing but make sure you pop open the hood
before you do this.
Then there are 4 screws connected to the steering wheel.
Then drop the steering wheel down then ya got the
dashboard and pull of the plastic cover to let you unscrew the
gauge face off. Unscrew that and then u unscrew the heater/
ac thing disconnecting the wire sensor. Then disconect next
the cable that opens the door in the ac heater core box. Then
ya unscrew the the air plug orange lookin thing. Then ya take
the ac button thing off and set it aside with the rest of the
parts you have taken off. Then ya take off the 5 bolts all on
top of the dash. Then ya unscrew the piece in the middle of
the whole dash where the cig lighter is and then disconnect
both plugs and then ya disconnect the 2 yellow and white
sensor things and then ya disconnect the chrome tip wire.
After that you are almost there. Ya can take off the panels on
the side of the cab and unscrew the big screw holdin the
dash on the driver and passenger side. Adter that is done ya
go to the middle and unscrew the two bolts in the middle of
the bottom truck an they are hidden under the carpet. After
that you pull the dash out. Then disconnect the sensor on top
then another sensor in the middle then the ac hose. And you
are set. Then unscrew the bolts on the firewall and pull the
box out. Before pulling it out ya need to disconnect the ac
lines, drain the coolant and disconnect heater core hoses.
Then ya can pull the heater ac box out. And reverse the
removal of everything. Simple right?
