I’ve had a new heater core sitting on my parts shelf for 10 years. Finally the inspiration to install it! Thanks for the video.
Same I stopped driving my mustang in 2012 because I didn't want to f#ck with the heater core and I put a 347 stroker in my 88 BMW 325is and it's more fun to drive and different. Just mustering up the ambitions today and started ripping it apart before I found the video.
D G hell ya man. It’s the hot season in the Midwest so the heater core is the last thing on my mind, but I’ll get to it by fall. BMW sounds sweeet
Man, this is what I'm talking about, a Technical Fox video, thanks for posting this, awesome!
There are Fox owners who've replaced them and Fox owners who haven't replaced them...YET!
I will be saving this video, thanks again!
If you have a mint car I suggest you pull the dash slowly and completely. Gives you a chance to clean rewrap the harness in cloth tape in places its come loose, clean the dash frame and replace dry rotted fasteners. Quick jobs are ok for beaters
The last time I did one was in 98, but I believe we pulled the whole dash and did not need to disconnect the a/c. So if you have more time than money, that's also the way to go.
Never understood the "quick" mentality,90% of the time it ends in disaster, i understand a "alternator, a radiator, only car, gotta get to work in the morning situation" but a job like a heater core, ill take 3 days if i have to, plenty of people that can take me to work if need be,i see these videos all the time,to each his own i guess, i do have to say my favorite is cutting up the trunk area on a Mustang to change the pump,Ive done so many i can drop the tank in 20 minutes and thats taking my time,not sure why you would want to cut your car up.
Done it four times over 24+ yrs on my 87. Got it down to under 4 hours, and never disconnected the AC. Drill with a flex shaft was a time saver! Side note, I knew a Ford AC tech that could do 3-4 in a day. He had all the shortcuts down.
Thomas Bailey in what city?
@@bigboy9350 Houston, Tx
So your 87 is on its 5th heater core ?
@@bryanroupe8646including the original, I guess it is the 4th. I've pulled the dash a couple more times changing interior color and the evaporator. I drove it daily 306k miles over 24 years. Did the first one at about 6 yrs. That one only lasted like 3-4 yrs. The 3rd one failed after less than 2yrs, cheap parts store POS. The next one (Ford part) was good for another 5-6 yrs before I changed the whole
AC system to r134a. A couple of years later, the motor blew. I hope it is still good after sitting the past 9 yrs!
@thomas Bailey what’s The Guy name in Houston tx, I’m here in San Marcos
Just did this today based on your video and only took 1:45 to do and I have been putting this off for awhile cordless tools make it quick. Thanks for the step by step
I once Installed the whole heater box/evaporator assembly in a 1980 Mustang from another Mustang because mine didn't have air conditioning. It took me three days because I had to remove all the dashboard and install the new ducts and a/c controls. Was very careful because the plastic dash was fragile and was afraid to break any part of it. Had to prop it up at different stages so it wouldn't break from hanging by a few screws. As I removed the screws, I would label them with masking ape because not all of them are the same; length, thickness or type of threads. Power drivers are great but when you are reinstalling some screws, you should start them by hand because the driver may strip or crossthread the fasteners before you are aware of it.
The electric ratchet looks handy enough for me to need one. I like the way he works. I'm same way tearing down takes longer put it back together. AWESOME JOB
Power tools make a HUGE diff, and those 1/4 and 3/8 powered ratchets are plenty cheap
I use my little M12's for everything and you can buy batteries on Ebay for like $12
This guy could do this in his sleep. Great vid! Keep up the great work. We ALL appreciate it.
Glad to help
Dam i did my 87 GT convt. Changed out the heater core but it took long long time i guess it was my first time doing it? I didn't have you tube to help out like a day's thank God for RUclips 🐺
On beaters, 2-3 hours. On clean survivors 5-6 hours because I replace dash clips, make sure the harness doesn’t rattle and trim pieces don’t come loose. Not a fun job but years ago when we discovered not yanking the whole dash life changed for us lol. There’s more shortcuts but those are for the OG’s to keep very hush hush.
Really? More shortcuts but hey, lets not share them because we're dickheads....
Man this brings back memories...
Had to do this back in '89,, to my girlfriends/now wife's '85 hatchback....Ford Dealership said they'd need the car for a week to replace it... Me, with some help from her Father, did it in two days...All handtools, with NO Manual to help...Had to figure it out as we went....Talk about fun...... Must have done something right,, It's Never been changed since....Still got both of them, The wife and the Car..... Oh,,, and back then,, Freon was a Buck Fifty a can at K-Mart...lol
Thanks for showing a faster way of doing this....'Cause I know it's only a mater of time till I'll be changing it again....
1988 Mustang GT convertible-
I just got my dash pulled back enough to get to the heater core. I couldn't have done it without your video. Thanks.
bob potter about to start on mine; any tips?
@@cristiangonzalez8527 take photos with your phone for reference. If you have AC, the evaporator does not have to be evacuated/removed. Move aside enough to get to the bolts behind the evap bracket.
bob potter I accidentally already evacuated it last year. Didn’t know any better haha. Couldn’t for the life of me disconnect the ac line though at the firewall. Had to disconnect the front part of it
My fix was I only drive it in warm weather now lol
c431inf 11b lol amen brother
Yup. I'm never going to drive mine in the winter anyway and I'm not selling it so screw all that noise.
@@JRC99 exactly, the second time mine went I bypassed it with a socket and some clamps that was 17 years ago 🤙 this things mine forever
The thing that impressed me the most was how he just threw the bolts and screws around! haha send it!🤘
Very impressive indeed! Dover is a Master Mechanic of the highest order for sure.
I was waiting for the shortcut but it never happened.
I liked this video because its not me doing it.
No shit I'd rather R&R the entire engine than doe a heater core.
I've done this a few times it's a pain but he makes it look really easy..lol
Took me 3 hours to do mine. Dover has it down!
Three hours is better than the first one I did, took me all day (following bad advice)
@@FoxcastMedia I want to buy a 86 mustang gt the car looks in great shape but the ac and heater are not working , the price is $3,500 not sure if it's worth it
Nice I have had to do this on every fox that I've owned. I also replaced the the blower on a few of them since I was there & had it all apart anyways.
Thank you for the video. I just replaced the heater core in my 88GT your video was extremely helpful.
I just did this about a month ago! Unhooking the a/c probably makes it more accessible but i left it hooked up and changed it out no problem
First thing i did buying my Fox was a burnout...that followed with a burning my foot after hot AF coolant spilt all over my thin shoe. Since then bypassed the heater core and been like that ever since. After seeing this video i think I’m ready to tackle it lol
Ha yupp rebuilt my first mustang and same thing happened to me. That was 25 years ago. Just bypassed it and went on too.
Thankfully i was able to flush out my heater core with some very light pressure from the garden hose. Saved me from having to take the dash out again. Same with my sn95.
I am glad the 86 dash comes out without touching the center console. Finally a 4 eye issue that is easier. i have changed mine twice in 25 years took 5 hrs the 1st time about 3 hrs the 2nd. Thanks for uploading. alot of people needed to see this!
Just finished mine THANX to this video...VERY HELPFUL !
That exactly how I did mine back in 09, took me 6 hours. It was my 1st and only time doing it. No RUclips videos to help.
The next day it was 7°
Heater core jobs are easy on fox cars! I wish i could make a living at changing them out for people. I thoroughly enjoy doing them.
I cut a hole in the firewall in my 85 GT. Made a spring loaded flap.
DAMIT it took me a whole day
It’s obvious this guy has done this several times. If you are not a professional at fox body dash assembly don’t get disappointed if it takes you a little more time that guy is about as good as it gets on knowing exactly what to remove and what tool it takes is usually half the battle
But showing you can do it is motivating
Thanks guys! You all are making my Fox Body resto so much easier.
Impressive. Replace and soundtrack equally impressive.
I had to do this on my old mustang years ago. It seemed like a terrible job, but looking at the drawings I came up with a shortcut and did the job in less than an hour. Take out the glove box and pull down the carpet behind the glove box and you'll see a thick plastic. Take a box cutter or other cutting tool and cut out a square around where the heater core should be and pull the plastic piece out. Voila, there's the heater core. Can't remember exactly what it looked like, but I was able to pull out the old core and install the new one easily. I put the plastic piece back in, glued and duct taped it in place, put the carpet and glove box back, and was done.
Much needed video for any fox owner! Great content!
I lucked out with a ‘79 I owned. It did not have A/C, only a heater core.
To replace it:
1. Drained the radiator.
2. Unscrewed the glove box and remove.
3. Unscrew the plate that covered the heater core and remove.
4. Unscrew hose clamps connected to the heater core and remove.
5. Slide out the heater core.
6. Insert new heater core and reverse above process.
Did not have to remove the dash.
Thinking about it, what saved me the most, no air bag.
Not saying air bags are unnecessary.
Thanks!!! Have an 83 and this video had me cursing already!
I pulled the plate and found the heater core easily accessible. (No a/c either)
The music got so much better at the end. What is the deal with the infatuation of "music" that sounds like a baby saying the same crap over and over again on RUclips car videos? Looks like that guy has replaced many Fox heater cores in his time. He made quick work of it! Thanks for the upload.
One thing you forgot. Dover is a boss with the foxbodys,but anyone else,do not just toss the screws anywhere. Separate and put them back where they go.
Well i ordered mine last night this coming weekend goin thru right of passage... Wish me luck
Starting my 88 fox body build soon. I appreciate this.
This is going to help me a lot cuz just found out got to replace mine and im not paying for the labor
People make a fox heater core out to be a much bigger job than it really is. Couple hours at the most, and that’s taking your time not to break or lose anything. It can also be done without dumping the A/C.
I bought my fox (first car) with busted heater core, I took it to a couple of mustang guys and the two of them had the car back to me in two hours. Cost $200, which wasn't a bad deal. That was in '04, now I'm sure I can do it in 2-4 hours by myself since I have tons more experience working on stuff...
They didn't mess with the AC lines either, it still worked and I know they sure didn't recharge it.
Standing ovation! Watching Dover work is like watching a virtuoso violinist or Michael Jordan, it's art!
I've done this twice (which took forever) and I never removed the AC drier...and I don't remember what the consequences were.
Seen ole JD pull many dashes. In many make and models. He is a pro at the tedious stuff.
I have a 84 mustang I've put 3 in mine in last 24 years, 1st time took me 2 days and lots of bad words. 2nd time I cut the front on the heater box where the heater core sits and made a cover for it so I dont have to drain my ac or unbolt the box from the firewall now. Last one I put in only took 45 mins.
Outstanding work, quite rare on youtube to get a worthwhile how-to video.
I was tired while watching this , I started dozing off when he took the arm rest off, woke back up when he was putting it on .😂was kinda trippy
The type things nightmares are made of. I can't imagine how it can be done so quickly, what a talent for a real tough job. Have done it on older model and it was no fun and would never like to do it again.
Man this video saved me some money. Wasn’t that bad of a repair. Thanks for the info.
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 great way to show the less time consuming way to do this job ! Kens hiding in the back ground when I buy another fox if I have to job I will know haw do the more efficient way to to do the job.thank for teaching how do this job easier 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
You should put an evaporator in it as well if your keeping the ac.
Great video. No fluff. Get the job done. Thanks
That's exactly the way I did mine. Took me 10 hours. Had to disconnect my A/C as well.
Exactly how you should bang out a heater core. I'm going out on a limb here but I'm willing to guess this cars been under water at one point? I'm also going to go out on another limb and say Dover is 6'4 or 6'5? He's crawling around a little fox interior
Eric Debisz Not sure about the under water, but I’m a hair under 6ft and he makes me look short a/f 😂
I did mine in like 6 hours.. I’m glad I did it because a shop wanted $700 to do it.
Dover works on these foxbodys like if he built them himself lol. He is for sure a master mechanic an u should be lucky he is your friend haha. Keep up the awesome videos.
Had mine done about 7 years ago, then it sat for a long time. I'm slightly worried it may be going bad again. None of those symptoms yet though. PS - Dover is FAST!
My old Ford truck was a PITA as well. Thanks Ford.
Awesome video guys Dover you rock brother all you guys do
Thanks for this amazing video ill be changing my heater core this week god bless.
Great video and heater core removal advice, thank you!!!
Oh and great videos thanks🐺
* tech tip . When changing the heater core ,rub some white lithium grease over the heater core tubes . It makes your instal of heater hoses much easier especially with new stiff heater hoses . Also when replacing the hoses instead of playing captain destructo and pulling the old off and possibly damaging a other wise good heater core ,take a razor blade and slice through the old heater hose and it will be a breeze to remove the old stock in hose with little chance of damage to the heater core . You can also use lith grease (a light coat ) on all coolant hoses (upper /lower hoses ,bypass hoses,heater hoses etc ) for easy instal and removal since you are likely the next guy to service the vehicle.
Hey from Ontario Canada ! MY 85 fox burst the heater core while mid-track in the quarter , shifting at 6200 rpm.... I think it was cause I just installed a new High volume Weiand water pump and the extra water pressure made it Balloon. Next time I'm gonna get the standard volume pump !
I did a similar stunt.. LMR has a restrictor fitting the goes in the heater feed hose to reduce the pressure. Be sure to get one or make your own. See jrichker at www.stangnet.com..
Dover is a beast!
Is there a way to make a "door" in the engine bay where you can just remove the hoses, slide the old one out and put the new one in?
Thanks for this video, helped me out alot! Love the channel
I used to believe in always putting in a motorcraft heater core when replacing it until my last foxbody that went through THREE!! I flushed the coolant, replaced all battery cables, grounds, new hoses with restrictor and still didn’t help. Every year it would start leaking. Put a spectra aluminum heater core in and not a single issue after that. I’m a tech by trade so a heater core is no big deal but having to do it every year was getting annoying really fast.
Great information 👍🏿
I think I will keep mine bypassed!!! I live in TX and don't need no freakin' heat!!
Not bad did mine in two hours.didn’t have to take out the console.
How in the world did you get to it without removing the dash.
@@graysonwilson3483 read original statement !
Cool, thanks👍
Great video
Dover making it look really easy 👍👍
Do you guys know why the air will only blow out of the defrost vents? I have a 91 and an 89 and both are doing it.
vacuum line on the engine side of firewall that connects to heater box is not connected or has a leak. not pulling enough vacuum. look on the passenger side firewall should a small plastic line.
Great info!!!
I replaced mine taking my time in about 4 hours and now I have a squeak whenever I hit a bump, which there are thousands of them in Houston. I don't want to remove my whole dash to find out what it is either. I've tried moving everything by hand and hear nothing. Only when I drive. I don't have another driver so that I could pinpoint it out.
Yeah that looked pretty easy. i did mine a few years back in a cold garage in February and i did not discharge the A/C . I had no way of doing it and didn't want the R12 to go into the atmosfere. I also removed the seats for better access. got it changed in 2 days vs 1.5 hours but it works now and won't be doing it again for a long time. Hopefully never.
What was he using a 1/4 drive ratchet cause I was thinking about about buying 1! I see a lot of people have a really hard time getting that front bolt out of the heat core cover! I was going to do mine in September but I had to have heart surgery good thing about mine I have a 87 coupe it's a 4cyl car I only drive it about 20 miles a day when the motor or transmission goes up going to drop a V8 in it but I am going to change the heater core while the 4cyl is still in it! That a/c canister u don't have to remove the lines it has a clamp around it loosen it up u can slide it up or down to get to the heater box bolt behind the bracket! But Dover in them it's nothing to recharge the a/c system! But I am glad I seen this Video I was going to take the whole dash out seats cluster unplug all those wires by the steering column! Dover is the man he knows his shit I wish I had a friend like Dover lol! Thanks for the awesome video Dover!
My buddy said that's the first part on the assembly line when they built the foxbody the rest of the car was built around it LOL
Thanks for the vid! I have to do this a SECOND time right now on my fox. I replaced it the first time two years ago. OEM core lasted 30 years, this one lasted 2! I bought the most expensive and highly rated one on LMR. I've heard some people say that copper cores are best as that's what Ford put in em at the factory and I think that many be true based on how long my aluminum (?) one lasted. Any suggestions on this?
Also, I didn't have to do any A/C evacuation on it the first time. Is this hard to do?
This man is asking the real questions.
Quality today is most def NOT what it was in the 80s and 90s; just yesterday, I had to replace the "original" 60lph fuel pump in my 93 2.3l mustang; replaced it with a 115lph. With every new CEO, to show they were worth the company's "investment" in them, what do you think suffers? QUALITY. EVRYTHING now adays is "engineered to failure" and nothing will last 20-30 years again; be good to get 10. I have a side by side fridge the previous owner left when I bought my house in '05, that was manufactured in 91 for Sears by Kenmore; I've NEVER had a single problem with water pump, dispenser, ice maker, compressor... There is no quality nowadays; EVERYTHING is throwaway and remanufactured.
Could you just cut through the firewall n pull it out them just put a custom cover on the firewall n paint it just a thought cause mine has taken a shit n I bypassed it for now but I don't really care cause I only drive the fox in summer anyway ✌
12:00...he ain't lying....my right side pipe came clear out of the heater core when I removed the hose
Bro great job this is going to be a major fox video if I can give you 100 👍🏽i would!!! Its a hit
I've got a 4-eye dash with OEM air conditioning. It's different from Aero foxbodys but still a pain due to the AC evaporator. Heater core works for now, but for how long? I had to do one on my old 1986 Mercury Grand Marquis and it wasn't too fun(the original looked old, crusty and brass/alum just like the one you pulled from this Foxbody FYI). Lots of scraped knuckles and F-bombs, lol. Hope I don't have to do this for a while...
Ask Dover if he'd come to Tennessee to do mine. I bought a car that unfortunately had a bad one and I didn't realize that before I purchased.
Good grief, this reminds me of the heater core I changed on my old mustang. I see ford used the “move 98% of the dash to do the job” theory. I have only changed one in a mustang and it was a 2001 model. I did it as preventative maintenance because the car had sat for a couple years and I was already changing all the coolant hoses.
Good how to though, keep it up.
If you’re replacing the heater core, would you recommend replacing the evaporator too since everything is pulled apart already?
Great video. Sometimes you can pour in a leak sealer that will fix the leak permanently. I had an 1987 Dodge Ram 50 that started to leak from the heater. I bought a bottle of Blue Demon and decided, why not try it? Saved me a lot of time and work, never replaced the heater, even sold the truck after 3 more years. No more leaks. There are several other brands of stop leak that probably work just as well.
elppedro77 that’s a great way to permanently close your thermostat
What tube did you put the factory restrictor sleeve inside the heater hoses???
Honestly its not as bad as everyone makes it seem i gota take my dash off because one of the last owners decided to removed the entire hvac box
Nice job guys!
Ok my cars a summer car for sure now lol
I need to do this to my XF Falcon Ute which is harder than the foxbody.
Dover be doing his thing he knows his shit!! 👍👍👍👍👍👍👍👍👍👍👍👍👍
I had a 89 lx hatch that this happened to and I live in Wisconsin. Need less to say I stopped driving the car in the winter. Haha
Very informative
I know this is an old video but how similar is this process in an 85 foxbody T-bird?
Always be gentle removing the heater hoses from the heater core. Use a brand new razor blade and slowly slice through the old hoses a little at a time until you cut all the way through. This is the best way to avoid damaging the soft metal and prolonging the life of your heater core.
If you're replacing the heater core and the hoses, why be gentle?
