ya i looked at that before i even started.

the one about how to do with without removing the dash is helpful

he said theres a clip in the back you cant see but you can feel.

i removed that with no luck.

too late though i got mad at it and beat it to pieces, nothin left now.

there were 4 more against the interior firewall that i dont think could be reachable & two pieces of plastic right infront of the heater core, so that must of been why it wouldnt come out.

i hope i can get another whole case with my new heater core in there in one piece.

im gonna try and figure out how to remove all the brass around the center councle safely, if theres any hope.

il be getting back to work on my other car and let'er sit a while.

i dont know how you people get all those 7mm bolts out right for the dash. there were 3 that were litterally impossible for me. the center cluster on on bottom right, far passenger near windshield, and another i dont remember. i had to break them with a chissle but it worked out alright, for the dash at least.

another thing broken, if only id of beat on my tree stump, silly me

i can be a little impashent sometimes, then end up having to spend alot more time.

if it wasnt my pony i was working on id of probably stripped and junked it.

i seen an escort at a jy with the whole center section of the front of the car cut out, now i understand why

the heater core is the hardest thing iv ever not done

There are memebers here who have cut a hole in the firewall behind the core and removed it that way. I was asking but never got a detailed how-to on that one. But if mine goes, I'm cuttin a hole!

Member-me. I don't have the car anymore, but it's not that hard if you have the new heater core for the dimensions to cut the hole. Make a pattern with the new core, and then add a quarter inch all around for the cut. You'll need to weld a lip around the piece you cut out, and put some weather stripping on it when you screw it back on. That pretty much sums up the howto. Tools required dremel/rotozip or equivalant and the means to weld the lip to the pice you cut out.

Thanks Trencher. My initial inquiry here came after I was looking at the heater core pipes disappearing through the firewall and wondering about getting at it from that side. Trencher responded and said he had done exactly that.

I dont need a core replacement at this time but it'd be great if someone tried this and took a good series of pictures. It sounds so much better than ripping half the interior out of the car. I suspect that after the initial hole is cut and a panel is in place it'd take 15 minutes for a heater core replacement.

It's extremely easy to get the heater core out after you get the dash out. Last time I did mine it took me about 90 minutes from start to finish. Neuman and I pulled a dash at the junkyard in about 40 minutes once as well. If you had any questions about how to get it out you could've just posted and I'm sure someone would've helped.

Pulling the dash really is a breeze. If you don't follow the manual. If you disconnet the heater/ac controls, radio antenna, speedo cable. You can then remove a combo of 13 to 14 bolts and nuts. When the dash is pulled forward you can disconnect 2 multi connector plugs and the speedo from the cluster and pull the dash as a whole. It takes doing it the hard way once to curse ford, chiltons, and haynes for instructing you the wrong way of doing it.

true that ^

i just pulled the whole brass bar or basically the whole front interior, too bad im not in a derby

im yet to stick the box in, mainly cuz the drivers side of the box i got has all the lever/pulleys for it missing.

i dont know how the hell you people do this without tearing the box apart

reasons being

1. the heater core is attached to the black box with 4 screws directly facied inside the engine bay. so if your to pull it from the inside it will still be held to the box

2. the plactic flappers inside the box keep it from coming out from inside the engine. WITHOUT breaking them, maybe not a prob if the 4 screws are out.

3. the dash isnt easy to get out at all (for me at least) with the brass or plactic tubes in the way and i tryed many many times to remove the black tubes with no luck.

i couldnt find any way to reach each and every clip on the box not to mention separating it far enough for the core with all the stuff in the way.

welding it from the engine bay would have been alot easier.

i really suck at this

i thought it'd be really easy cuz iv taken out the cluster,center councle,glove box, etc on different occastions and wasnt expecting this to be so complicated.

well 3hrs later im done.

its was alot easier for me when i took the bracket off.

took about 5min to get the heater core box in that way.

did take a bit of time to get the bracket back on but not too bad.

i jumped to all that too fast.

only prob was i forgot to put the pcm (orsomethin) & bracket behind it before i pushed it in.

il just tape it in.

wheew

i was searching for one of those wrenches that work like a rachet but i think the lowest they go is 8mm. i love those thing, preferably the ones that can flip back and forth. when you buy wrenches that expensive you rarely lose them

Did mine few weekends ago and it definitly SUCKED like everyone else, but once it was done i remember thinking "that wasn't actually so bad"... so don't get too discrouraged about pulling the dash apart, i printed the entire how-to post and just had it with me, helped A LOT... as well as the wratcheting wrenches, those things are a must have for all jobs i'm finding

ya cant complain about how-to's they can save you alot of time.

id say its done but it aint over yet

im missing the controls to the temperater guage, since i beat it up and got one from a jy with them already pulled off that side. replace the other half but it will be alot easier & quicker since i know how to do it.

i drove all winter last yr with no heat under 30F so the time will be well spent, in the end.

FYI just did the heater core thru firewall on my 86 GT with factory A/C. So much easier and faster and when it happens again it will take maybe 10-15 mins! Wouldn’t even notice it unless u really look. Simply traced out heater core with sharpie. Used grinder to make small hole maybe 1in bigger than heater core then Used a dewalt oscillating tool to cut thru plastic like butter. Took maybe 30 mins tops to access the heater core. Spent maybe 20 mins making my access door from sheet metal. while the paint was drying I used that chrome tape they use on heat vents in homes to seal my plastic square I cut back together. Put on my foam strips like they use on windows and doors around the hole and screwed it down. Sealed up perfectly. The heat is absolutely perfect in it now. So maybe 2hrs in it. Forget taking dash out that’s just insane for a heater core. Spent rest of day with family driving around with heat.
