- Part 2 goes over the process of opening the heater box, swapping out the heater and AC evap cores and quickly reviews the dash and components reinstall.
As much as I dreaded this job, it actually went well and now I have beautiful heat and no more coolant smell.
Thanks for watching.
Leave me a comment. Anything I could have done better?
Great workmanship !! Good filming techniques. Now all she needs is interior LED lighting !
I just R&R my engine after getting it rebuilt, and on my first drive I noticed the heater core leaking. Grrrrr. I was going to pay to have it replaced, but after watching your video's I think I can probably do it. I will use them as my guide. Thanks so much for taking the time to make them. Stay healthy..
Thank you!! This job is somewhat tedious with all the little things you have to remove but it’s “easy” and way cheaper to do it yourself! Glad you found the video helpful! Good luck!
Thanks for the great video! Help to others who may do the same repair. I decided to test all the controls before I put everything back together. I had WEIRD electrical stuff going on. Turning on the heater fan turned on the dash high beam and turn signal indicators. The blower fan would only engage when I turned the interior dome lights on, otherwise the resister hummed. I ripped out all sorts of stuff and spent 3 days hunting with my multimeter for a short. One time I had the entire heating system working until I slid the dash back in, only to have my problem return. Finally figured out that I needed to button up the metal screws on the bottom on each side of the dash to get enough of a ground. Problem solved! 😀
Very much appreciate the xj heater core series. Gives me motivation to knock out all of the heater core and ac woes on ours. Cheers B
Thanks!! It was a big help to me. Since I am apparently the "Chief cook and Bottle Washer and Heater core Changer" anymore. I try to read up on all I can find. Yours was very helpful to me. I will be removing the front seats for more room as I am handicapped and will need it. Thanks again, Teresa
You sound just like me, minus a few other choice words, when im wrenching on my XJ. Good work on the videos! Doing my heater and evap core these next couple days.
Thanks for this. I was about to pull my dash out to access the vent cowl that is leaking all over my floor and I realized if I am going to dig that far in, I might as well swap out my poorly performing heater core and leaky evap core. Take care of it all in one dash dismantle.
A fellow jeeper who also uses the blue ryobi if mine had an hour counter lol thank you for going threw this process prob the best video on this job i have done this one 3 times now but never had time to record it
Heck yeah. These blue robin tools last a long time. Literally have had them for over 15 years!
I will gladly pay my XJ Dealer 👍😊. Fantastic video ✌️
Oh yeah..Totally...It's "fun"...Glad you liked the video...Hoping that was the last heater core I have to install...lolololol
@@JustJeep_It You have the patience of Jobe- that task was no joke. Stay well and long live the XJ👍😊
Doing mine. At 14:47 - I understood every word!
Best video out there. Thanks so much for taking the time. Just tackled this and am about to charge the system. Would like to buy you a coffee, how can I do that?
Very helpful video, and well done, thanks! Most of it applied to my 89 Comanche. Key differences: after ordering parts and opening it all up, my AC turned out to be a dealer installed option version. Evap core was smaller than factory, and all sources (that I could find) had only the larger factory version which would not fit in the box. Original mfr doesn't make it any more. Luckily the core was basically ok, so I cut and soldered new fittings to fit new Expansion valve. Easier than trying to make a new box or get one from the junkyard. Also, being an 89, many of the gaskets/seals and other foam parts were rotted out so a lot of custom weather stripping was needed. Assuming the dealer installed option applies to several model years, I suggest that others going at this job look at the box size under the dash before they start so they know what they are getting into. A box that is smaller where the Evap core goes than what the video shows would take folks on a different path.
Great video made my xj heater core a breeze 10/10
Great job! You made this video perfect by not showing the obvious. Love the Arnold bit. I do the same thing! ARgggg.. Get to the chopper!
Thanks. Glad the video was helpful. And glad to meet another Arnold impersonator lol
Your video was very helpful and want to say thank you! Took me about 10hrs or so. My northern michigan XJ is ready.
I’m glad this helped you!!!! Good job getting yours done!!!! It’s a good bit of work but it’s done for a long time
you did a really good job my friend well done,very informative as well,a great guide to how its done.all the best and take care.
Thank you very much for the kind words. I I’m glad you found this video helpful!
Nicely done! Also good to see I'm not the only one with XJ grill keychains.
Thank you!! And yes. I got mine from ironrock offroad
The part one is good but I wonder how you wiggled that center console out? I have been working on mine for a couple hours.
Very thorough video. I didn't see the evaporator drain hose . Doesn't that get connected to the heater/evap box, so any condensation gets drained to the street? Thanks.
Yes. The little hose attaches to the box to channel water away from the firewall.
My heater core leaked for two years.
The air conditioning compressor died 2 years ago. So I just moved the heater hoses from the heater core tubes to the evaporater tubes.
My heat is fantastic & no more fogging on the windshield!
Just had to make some adapters because the tube sizes are not the same.
Literally genius idea. I’m going to repost this. Thanks for sharing!!!!!
@@JustJeep_It Glad to help, whether it's a Jeep or any other vehicle.
It's been hooked up for 6 months, over the winter, & no leaks.
I might add a ball valve to reduce or shut off the hot water flow. There's too much heat unless the weather is below freezing.
Solid videos, thank you very much! I just picked up a 99 Cherokee Classic and there’s a coolant smell when the heat is on, “wispy” streaks on the side windows, and the entire cabin fogs up like crazy. I haven’t used the heat, the defrost works fine on cold and keeps the windows clear, but I miss the warmth 😂. Thankfully the heat is still hot, I’m probably catching it at the start. I’ve done a few heater cores on German cars/SUVs and those were 15 hour jobs, thankfully this seems way less difficult.
So I was out in the rain for about an hour and couldnt get the three bolts on the right side in... Finally figured out that it wouldn't move forward because of the drain tube lodged in hole and wouldn't go through. Took that off and it slid right in (all five bolts). I hope this helps others as it is not easy getting the box back in. After that, everything else was a piece of cake!
Awesome. Thanks for sharing your experience!!!
Nice job Joe.Im glad you didn't have any issues.I got my heater core project done but ran into an issue.There was a broken blend door inside the box when I opened it up.Not a big deal really,just another $100 to replace it...Ouch.....lol......
Thanks Dan!! Good luck with your heater core swap.
Nice 2 part video! Ill be doing the heater core and evap in a couple weeks or so. Quick question though. Which heater core and evap did you buy? Did you just get them from autozone? On a few forums, people say to get the brass heater core but ill be happy just having heat again! Lol
Glad you found the video helpful!!!I think I got whatever was on rockauto. I think it was aluminum.
@@JustJeep_It Thanks for the reply! Sweet I’m just gonna order that one, and get the evap also. Im looking forward to finally having heat!! Lol
@@bdr5150 just about to order both heater core and AC evap from Rockauto too. I am a little bemused as to which one to get as they list several different one. I live in the Netherlands so I really need to get the correct ones shipped? Do you know which ones you got and did they fit properly?
I'm right in the middle of this. What brand heater core did you get? The UAC brand from Rockauto pipes were not bent exactly correct and I didn't want to bend.
I got the heater core from Autozone. For my 99 XJ, the part number was. 98024.
I was going to go with rockauto for this but the deal was a few bucks cheaper with Autozone.
The rockauoto GDB brand looks like it would work.
Let us know how it goes!
@@JustJeep_It thanks for the info! I just checked online and the local AZ doesn't have one but the orileys does. Of the orileys doesn't match up ill get my local AZ to order that part number...thanks!
I have noticed some vendors make the parts spot on and some are kinda off-ish.
@@JustJeep_It finally finished, got a part from orileys that fit perfect, thanks for the info
So Im trying to finish this job up but my steering column won't go back in place. The bolts for the 13 mm nuts are not in alignment with the holes. Any idea how to resolve this issue?
I know this isn’t helpful, but it should just go right back up. There really isn’t too many things getting in the way of the steering column. There are two studs that come down from the dash. You might just have to wiggle that thing around to get it all lined up. And you are right, I believe they are two 13 mm bolts.
I had to mess with the steering wheel adjustment level on the left side of the wheel. Messing with that and the mounting plates you can change how the holes and studs line up
@@Timk0810 He means adjustment *lever*
Doing this now on my 99 nice video
How is your aluminum heater core doing? I just replaced mine with an aluminum one too and found a video someone claims how unreliable aluminum cores are... Hope yours is alive and well!
Did you have the ac system re oiled and charged up also?
How did you get the steering wheel bolts to line back up? I followed everything you did but the bolts are not re aligning and didn’t want to break anything.
Hmm. I just lifted the steering column back into place and the bracket lined up with the 2 bolts from the dash. Is anything blocking the way of the steering column?
The plastic was having a hard time slinging in after I lined up the bolts. I took that spring off and it went on much easier! So I’m all good and got it all back together!
Thank you for the reply and the overall video! Most helpful one out there for what to do!
Was there a special way you got the steering column back on?
This was really helpful. Thanks.
Glad it was helpful! Thanks for watching..
Joe, I've heard it's really a good Idea to replace the heater/AC diverter in the box with an aftermarket metal flap replacement. Do you align with this and if so do have any tips where to get it? thanks!
Yep put it all back together and the diverter was broke didnt know it.
Anyone not have a hole for the ac prob for the new ac evap? My old one had a hole for the old ac probe but my new evap does not have a hole for the sensor not sure what’s going on.
Was there any sealant around the seam of the box?
I think there was foam padding.
The A/C Radiator: A.K.A: The bug and mud filter. Clean or replace. Spray from the back; before you install the main radiator.
Thanks for your video Joe 🙂
You got it!!!! Hope you enjoyed!!!
Did your steering column not line up very well
No issues with lining up after installing. Are u having issues with it?
Hello.. ive watched part 1 and this vid a 100 times just completed the heater core job was t actually that bad following your steps. I do have one question i put mine all back together today and my blower fan wont turn on i get a humm out of the relay replaced that nothing replaced the resistor nothing im lost lol and no good with electric any help anyone?
Don’t know if you still have this problem, sounds like the fan is hitting something and so it is stuck. Try to turn it by hand to see. I think you can take it out from the firewall from the engine compartment to clear the problem.
i had the same issue with my fox body mastang
My blower motor died. Thanks GM.
Does anyone now where the last 3 wire connector hanging from the heater box at the end of video. I was unable to find wire it could pug in. 1-27-22
Anyone not have a hole for the ac temp sensor to go into the new heater core?
How many hours do you think you spent on it?
I think I’m total I spent about 3 hours.
They have a great cargo mat also………🤪
when i started mine i had brown hair !
dude wasnt it springtime when you started this? lol
I think it was in the fall. Cant remember
Awesome!
Fun job to do right? Haha
How to remove glove box door ?🤔
There are a few screws on the bottom and 2 rubber stoppers inside the door. Just pull those out.
lol just got finished with this. little tidbit REMOVE THE DRAIN HOSE!!!!!!!!
alsoooo if the ac lines are hard to snap in like mine were. take a open ended wrench that fits on the fitting and bap the box end with a rubber mallet or something. theyll click into place.
the evap core needs that foam top and bottom to force the air thru the coils not for moisture control! oops!
If it were mine junk yard.
The guys that design cars apparently don't work on cars......
