Thread: Heater Core Replacement

the console "has" to come out, seats are up to you. as your the one on your back on the floor board. i took mine out, its extra room. and its only 2 bolts per seat, whats the big deal?

theres other how to's with real pics too. take a search for them.

what the whole crappy job amounts to is removing every gold bolt you see around the bottom of the hvac box there, theres 2 layers.

and of course, leap frogging from one side to the other removing these bolts.

a good flash light or small drop light is a huge help, as you cant see jack for a lot of the bolts.

a beer or two to loosen yourself up helps, as well the aspirin for your back when done.


i dont know if it said so in this how to. but take the hoses off the alt bracket, and blow the core out, this way you dont spill any in the car when taking the core out.

and on the firewall from the inside is a screw holding the two tubes to the wall. you can see it sticking out on the outside of the fire wall between the in and out lines. thats the last bolt you'll get out. then the core will come out.

Jerseydoggs:

Interestingly enough, on my 2004 Grand Prix there wasn't a screw on the firewall holding the two tubes
in place. Once the heater core was exposed and the hoses removed, the unit slipped right out.

All:

What brand heater core do most people use as a replacement. I bought an OEM AC Delco Heater Core
from Amazon and I'm a little concerned that the two crimped on tubes can rotate with not a lot of effort
(they aren't loosey/goosey). The tubes on my original heater core are crimped rock solid into place and
don't rotate.

Is this normal? Just seems like obvious place for a new leak.

I'd hate to get it all back together and have it leak again right away.

I used a dramas one. Hoses moved around easily

Yes the aftermarket ones are meant to rotate so that you can get them into proper orientation.

the dash stays put, no need for all that jazz.

I did not remove my whole dash, but the job wasn't fun.

oh, no one said its pretty lol

LOL. The worst thing about that day is I was struggling with a sinus issue as well as a migraine. I crawled out from under the dash one time and thought I was going to vomit due to the caused disorientation.

that looks about right, left side get in undo stuff, right side find and remove more stuff, back to the left side over and over again lol

What's with the lighter on the floor lol?

read the posts man.

On 04+ the covers are held in place by plastic stakes that are melted. Dumbest design ever, but then again it is GM.

04 up are special, got extra dumb stuff added.

i looked the taurus one up, and wow. thank god moms didnt need one. but the dumb ass heater core water line circle aka by pass lines rusted out, now thats no fun to change.

what a crap idea they had. ford at its finest......
