How To Change Your Jeep Grand Cherokee Heater Core In Less Than An Hour 

Your doing someone a good solid by doing this tutorial. You don’t even know how many people this will help. When it comes to Jeeps your the man.

3 hours. It took me 3 hours to watch this video 2 times and get after it, only watching sections along the way to double check the work. I don’t have ratcheting wrenches, or swivel sockets, mine still had some harnesses attached to brackets that his doesn’t anymore, other than that it really was that easy. No specialty tools required, and a second person is optional. 3 hours start to running errands. Thank You Dex Jeeps.

I would not expect someone doing that same job 5 days per week, all year long to be able to do just what you did in an hour. Honestly, I’m sure most mechanics wouldn’t believe that much work could be done in 60 minutes. Quite impressive. 👍👍👍

Just did my wife's on the weekend, so it took more than an hour BUT you saved me hours of unknown figuring out stuff! Thank you so much! Wife is happy now. Slight change on my 2004 the two drivers side main bolts were 8mm not 10, as well its a V8 the heater hoses were unbelievably hard to reach and disconnect 😪.

My 13 year old son, Reid watched this video and wanter to try it on my 2000 Grand Cherokee we had recently bypassed the leaking core on. He did most of the inside work, I did the under the hood, mainly because of AC. Parts store gave us wrong part and it rained whiling trying to exchange, other than that it went well. Dax you are inspiring the younger mechanics and showing some of us older guys a better way. Thanks!

Awesome video! I have 3 WJ's and I need to change the evaporator core. No A/C and it's summer time. While I'm in there, I will change the heater core and fix my blend doors. Can't thank you enough for this video!

Man I feel like I need to buy you a 🍺.. just replaced evaporator and heater core while I was at it .. took about 4 hour and that’s with pulling a vacuum and charging system., it probably would have taken 8 without this video.. thanks much !!

Just finished mine. You made a awesome video. Need more people like you in the world.

Dex you are definitely a mad scientist!!!! Keep the videos and shorts coming. Thank you sir DEX!!!

Excellent tutorial video. 1 Hour to do this job seemed impossible at first but you made it look very straight forward. It would be great to have you for my neighbor. Thanks

I just did mine today with the help of your video. Thanks!

Nice to see someone working on real 4x4 vehicles . Great work . Iv got a 98 TJ my daughter has a XJ my grandson a XJ my brother Has a XJ . Iv also owned 2 new TJs 3XJs and a 1980 FSJ with the AMC 360 and T/ Flight man that was a weapon and one of the best’s exhaust note of any V8 and iv owned many MOPAR V8 some Ford V8 but that 360 AMC sounded so healthy 👍🏻💯🇦🇺⛽️.

Okay, fine, I’ll do it! Srsly, thanks for this. I did a heater core bypass and was gonna wire in a cab heater for defrosting, but you’ve helped convince me to give this job a try for REAL heat inside. Thanks! EDIT: Well, it certainly wasn't under an hour! You da man... Two competent wrenchers hacking at it and it still took basically two days. A couple snags and familiarity account for quite a bit of that time, plus the V8 has MUCH less room for working the heater lines under the hood. All that being said, this video is GREAT! We referred to it many times. The one thing we found was missing: the defroster outlet "trumpets" have a clip connect the aft edge to the fore dash edge, that's the thing up by the windsheild that was binding for us (and maybe what you were remembering). Otherwise it was basically as you showed in this great tutorial! Thanks again.

The rubber bumpers on the glove box hinge on one side. If you sit in the seat and reach in, palms up, you can push the box in just a bit and hinge the rubber stops out of the way and the box just comes out without any resistance.

Damm, you really know your Jeeps 👍👍👍👍👍👍

Hard water will wreak havic on your heater core , radiator, water treatment is essential, if you use distilled water, and coolant, this will cut down on these problems.

This video will come in handy, I got 2 to do

Love to see a write up on the 96-98 ZJ. I'm dreading pulling mine but everything is pointing to evap

thank you for the video. keep em coming. why do 96 cherokee starters fail so often?

I've been putting this off for ever! 😂 But I'm finally getting tired of the foggy windshield, the low coolant dinging and the hint of coolant smell. 🥴 Just crazy how it's such a jigsaw puzzle to do it.

I be damned Dex, great job !! I'm 68 and need to replace my evap on my sweet lifted 01 grand. I sure as hell can't do what I used to. I would trust you to do that job ASAP. Where's your shop? I live in northern Delaware.

Dex... Thank God

Great vid Dex! I have a 2001 my evaporater is shot. I want to follow your heater core video and change both evap and hearer core. How far from Brooklyn are you 😅. I thinking about giving it a shot.

Thanks!

About to perform this surgery on my Jeep a rewind video how to put it back together

great video. Thanks

Excellent video, very well done. Just a question. At 24:44 you were talking about getting a “ piece” back in……..we’re you referencing the floor vent tube? Thanks

Best man Thank from Spain Andalucia

can I ask if anyone knows - do you have to vent the AC lines for this? Did not notice it was in the video, but the AC vent looked like open at 14:52? Please respond, and thank you for extremely good video!

On the glove box removal I know a easier way before opening the glove all the way take a screw driver put it at the bottom of the glove box between the middle plastic clip and the dash if done correctly should just pop that middle off without breaking it and the glove will just fall like mine without breaking the plastic

Anything else needed to also change actuator doors while in there?

Yoo man help , if I replace the heater core on my 01 jeep grand cherokee will I lose the a/c refrigerant

Aint no way! Haha nice tech video

so jack harlow is a mechanic now huh ? lol God bless bro

He’s funny for that Freon comment

How many blender door actuators are in a manual AC

I done it just like you sowed. When I finally finished, my jeep would not crank, no lights, no horn. Any suggestions

Do you have a shop or business where you do these repairs? @DeXJs

Thank You!!!!!

Can I do the same procedure for 2005 Laredo? Any one

Dex at the beginning of the video you said it was a grand Cherokee 99to 04 though those were 99 to 06 maybe there a difference in the dash for the last two years? And could you do a video or tell me we’re to find the module for the keyless entry is located I have a 01 grand Cherokee and it stopped working?

Same way i do xj heater core

I changed and put everything back in, but now all the electronics stay with the key off and out of the ignition, and the key will not turn over

Hey. Man I watch a lot of your videos I have a 1999 grand Cherokee 4.0 I'm having some weird reving and high idle I've changed all throttle body sensors checked vacuum lines and I can't find anything it revs up super high on start up until you put it in gear then it acts normal but if you shift it to neutral or park it revs up again if you have any thoughts id really appreciate it thanks brother

What is the seat belt inside the dashboard for?

Whats with that seat belt? Lol

I would rather set the vehicle on fire than do all that. I dont need heat....😂

FOUR heater cores in a just a FEW YEARS! ....wow....total chinese junk.....

Lmmfao 🤣, dog treats not drugs 😅

This is a complete lie it takes at least 4-6 hours

yall boys know what style is I got th crystler 2005 liberty 🤢

Having taken this dash off a 2001 Grand Cherokee three times previously, I can't thank you enough for this shortcut video. First time was for the blend doors, second for the heater core, third time was for the evaporator. Heater core started leaking again, so today was the forth time and I followed the video the whole time. Took 45 minutes instead of 4 hours. Food for thought, I noticed my 2001 had a 21 lb radiator cap from the factory. I have been through 4 radiators along with the 2 heater cores. I noticed the superceded Mopar cap that they sell for my Jeep is 18 lb now. I bought one to install with the new heater core. Maybe it'll buy some additional time on the cooling system components. Thanks again!

Great video!!! To anyone about to try this; a 10-pack of different color paint pens and ziplocks will help you stay organized if this is your first time. Before you remove something, dab the bolt and the hole near it with a color. Use the same color for all like-sized bolts of course. For us non-mechanics, it helps a little.

For clarification, what hangs up in the middle are the defroster vents, and then on each side, there is a pinch clip to release the dash from the A-pillar. Awesome video!

well a ieast I know who to go and see when my heater core goes bad !!! that was another great vid Dex !!! Lets see Transfer cases and 2wd Front Axles made into 4x4 ??!!

dam dude. I think I want to call you out just to see that done real time in under an hour. It took me all weekend lol. Amazing!

Best diy RU-vid auto video I’ve watched. Gets right to the point and explains everything quickly/efficiently without rambling.

I’ve always been intimidated by the prospect of pulling a dash for any reason. So I’ve never done one. This video gave me the courage to do so and I replaced both heater core and AC evaporator. Got it all back together with no extra bots or screws hanging about. Took me more like 4 hours; not bad for a first timer! Thanks so much. I wish I could find a video like this for my other cars.

Dex, perty please sell me some seat belts for a 98 XJ.

Thank you for this! Lifesaver! Heater core decided to bite the dust a week before we move!

Outstanding video. I did a bypass on mine. It started leaking a month after I bought the Jeep. I used to be an auto mechanic years ago I’m also an aircraft mechanic. I was honestly cringing at the thought of changing the heater core out. Thanks to you. Not now. I will replace the evaporator at the same time. Thanks for sharing.

Dam wear is your shop at .I have a wj that needs the heater core plus the bleed doors fixed ..I can't work on it anymore.i lost my eyesight to cancer .so looking for some one to fix my jeep for us

Appreciate the video

Wow I have to thank you so much for this video! I just completed my heater core, reservoir tank and the alternator work. You definitely walked me through these steps properly to disassemble and reassemble the dashboard. I did have a bit of help but in all this was pretty simple work with your help. 🎉

I used your video to get completely through this repair on a Saturday. Thanks a lot! Now I have to get the AC lines sealed back up. I think i lost an oring or something.

Glad that I just found this video, I just ordered the heater core and, get to doing this weekend. Thank you for your video.

Can you do step by step on xj the older one please just watched the end ish of this video and am awaiting the video on a xj core

Moral of the story is I won’t be doing it myself 😂

Outstanding video and details, love your style, oh and the dog treat treasures- hahahaha.My evap core has a leak so while you’re in that calamity- change the heater core too. I’m going to Follow you and look at your Channel for evap core R&R.

Thank you dude, motivated me to get in and change both cores today. Wasnt bad at all with your method! Went together a little slower from memory but only bout 2 hrs for me ! Never woulda thought!

This guy rocks. Great job. Please keep the Jeep videos coming . Awesome work

Good video and great advice /tips.

Well now I just pulled the passenger side plastic off and decided to come check a video out because it looks like will need to pull a lot more stuff off And I sure don’t want to Then I found your video Great detail So now for sure I don’t want to do it Ware is your shop located And for now I’m just blocking the heater hoses off and putting on a bigger jacket Nice video

So is this comparable to a 2010 Jeep heater core replacement? Can’t find not 1 video for a 2010 nor does anybody want to do the shit so I’m forced to DIY

Awesome job! I’ll be doing it this weekend

Be better if it was a copper heater core would last longer .👍🏻🇦🇺

This is simply brilliant, I just wish you could do a 2012 Ford Edge Ecoboost. It will help do so many things I always wanted to do by removing the dash. I don’t even trust anyone claiming that they know how to do this job because many so called mechanics where I’m at end up breaking and damaging something.

Since you know alot about these and a variety of other jeeps I want to know if the XJ heater box with AC is the same as a1998 TJ. I'm in the process of helping my 13 year old daughter to do a frame off TJ restoration and it does not have AC. Any knowledge would be great! If it fits then I'm in the market for the complete box and control panel for hers! Thanks, Christopher

Just watched your video for the 3rd time- tremendous!! t 11am on 7/19/24, my son and I will undertake this project. Not for the heater core but for the evap core- while we’re in there- the heater core as well. I can’t thank you enough Bro- great video 👍🏿

Execellent job on clarification, explanation of removal and technique used. And stayn organization of nuts n bolts to to thier respective sides

Do you have a video of this for an XJ? Are they wildly different? Mine is a 1996 XJ Sport (Manual) Oops, I see you don't yet. I am waiting at the front of the line! Thank you!

I have a 2001 4.0 Grand Cherokee that will overheat when i drive it. It idles around 210 and won’t overheat but once i take it for a drive for around 20 minutes it will spike suddenly and have to turn the car off. It will spew out the radiator cap and the coolant reservoir will start bubbling. The head is brand new on it with no gasket leaks. I’ve replaced the thermostat, radiator, and heater core so far. Going to replace the water pump today but if it isn’t that what else would you think is wrong with the car? It runs perfectly fine other than the overheating issue.

I fully believe that if I did this half a dozen times, got 8 hours of sleep, drank a Bang Energy, took a 2mg edible, threw a top deck 6mg Zyn in and had to pee. Yeah an hour sounds smooth. My first attempt will take me 2 days

Used your video as reference to change the heater core in my 2001 Jeep. Your videos was extremely helpful thank you for making this video.

This week I went to a mechanic's shop, the cost was 1,485.00 dollars. for that job. 6 hours of work at 135.oo dollars an hour. plus the piece😂😂

Have you ever had a problem with AC on the jeep? I have issues with mine i cant solve. Out of all the vents 1 only blows hard. I will take advice if anyone has any to give. Please snd thank you

I suggest using a product like KOOL-IT or RedLine's WaterWetter which will reduce electrolysis to negligible amounts.

Have you found what brand of heater core has held up the best. Are the cooper ones better than the aluminum ones? Thanks great video!!!!!

Pain in the ass to pull the dash just to replace a heater core. I do the air flush, scale remover, whatever I can before core replacement. Pain in the, well, you know....

One important lesson I learned here - heater cores are highly overrated! 🤣

Is this how you access the blend doors this as well?

wished you lived around here so i could hire you to do mine.

How bad is a heater core change in a 2010 jk??

you said 45 min ,,dealer said 15 hours gurr

WOW! That was unbelievably informative! You are killin it! Thank you for schooling us on this!

The video was great and it helped me a ton with mine thanks alot.. keep mKing em videos man!!

You ROCK

Why do the6 need replaced so often?

Great informative video!

can u do this on an xj also
