You can use a hole saw to drill an inch hole into the heater box and then you can use the stock floor plugs to plug it. That way when it gets dirty or filled with junk, just pull the plug and shop vac it out. What used to take all day now takes five minutes.

"Goddamn engineers" he would say. Everything was tightly packaged so as to minimize the physical size of the engine in its cowl. Its just that he couldn't get to the spark plugs. He thought that every engineer for every mfgr should be required to be sent out into the field to try and repair their creations. Personally, I totally agreed with him. Can we imagine some Jeep engineers trying to get to a heater core on one of their JK designs.? The instructions.. "change this heater core, and you've only got a standard rate hour to do it."

Did something similar to my JK. Supposed to remove the whole dash to get the heater core out, and they fail all the time. If you make a small modification to the dash frame behind the passenger kick panel and cut the heater core lines you can slide the core right out into the passenger footwell. Then you cut the lines on the new one, slide it in, and connect the lines using heater hose and hose clamps. Took me less than an hour instead of 6 hours and has been working great for 3 years now. Saved myself about $1000.

As an old-time mechanic myself, I agree that this mod will definitely add value for the customer in not having to pay a bunch every year or so. There is one thing I might have done, however, and that is to carefully measure the outside dimensions of the Jeep core, as well as the positioning of the intake and exhaust hoses, and try to find a heater core from another manufacturer that would fit, and that is also readily available, so he doesn't have the same problem you are having in finding a replacement core. Besides, that substitute core would probably last a smidge longer than a Jeep part. I replaced the heater core on my '85 K5 Blazer about ten years ago for a cost of $11.00, and it's still going strong!

I've encountered this problem before on few different vehicles. What I did to solve the problem with the lack of the original part was to find a similar sized part from the paper catalog at O'Reilly's and purchased that. If the hose connectors are different, there's a way around that. All that matters is the core itself fits in the allocated space and causes no issues.

Easy - it's much more expensive to build it like that. All those extra panels, screws, seals, it all adds up to a significant extra cost per vehicle. And despite what was said in the video, heater cores really DON'T need replacing every year, they're more like a once-every-10-years kind of thing for most vehicles, and plenty of owners will never need to even think about it. So making heater and evap cores more accessible really isn't a priority for ANY vehicle manufacturer, since they typically don't need replacing until the vehicle is 10-15 years old or older.

Extra holes in stuff requires more seals to keep air in and water out of the cabin. Access panels are good but have their own problems.

[@thekikendallsautoandrandom1271]

Early 90s GM trucks were dirt simple to change the core out. Takes fifteen minutes. No dash removal. There was a plate on the passenger side under the dash, 6 or 7 self tapping screws pulled the plastic plate loose. 1 screw on the core, disconnect the hoses from under the hood. Literally one of the smartest factory designs ever...

In my opinion if you know your going to keep a vehicle for a long period of time or until it blows up then both mods are absolutely worth it. Because once you replace the parts once, more than likely your gonna end up having to do it again. Especially when you cant or dont use OEM replacement parts because the cheap Chinese replacements will fail much faster than the OEM one did. And sometimes even the OEM replacement parts dont seem to last either.

With care, and guidance from a trusted source, this can be done from the engine bay with a small cutoff wheel. The risk is cutting into your heater core, which is what you’re replacing anyway, so….. yeah…. Don’t ask me how I know this.

[@Stanjara]

I don't understand why is it so baffling to a mechanic that a customer wanted something like this. Guys this is so crazy... why? That's the best decision this customer made.

Having helped a buddy do a heater core swap on a TJ, I think this mod is genius. It is disturbing that the part isn't available.

Yes and why can't someone make a better heater core ? doesn't look like rocket science !!

[@TeddyPatrickS]

I would 100% pay more for a jeep with this mod. A modification that is done professionally and makes the car easier to work on without harming functionality or aesthetic (yes a hole with a panel on the firewall but I wouldn’t care or even notice that… not like jeep engine bays were designed to be pretty) seems like a great mod to me

[@Iconoclasher]

A good radiator shop could fabricate a new heater core. I had one fabbed for a Nash once. I disagree with your assessment. A true Jeep Guru would probably appreciate the modification and gladly pay extra for it. I would!

Very nice, clean TJ! So little rust compared to ours here in Michigan. Those fog lights are indeed factory.

[@Ornelas11B]

Pure Michigan. I’ve got a rust free 05 Ford Ranger that I drive in Michigan winters. It’s such a beautiful truck. Paint shines like new. I just got it back last week from having a brand new Jasper engine installed. Timing chain went at 192,000 miles. The famous 4.0 Ford V6.

[@AdamIsUrqed]

@@Ornelas11B I had a '96 for 11 years. It went 334k miles on original 4.0 and transmission. If I could have afforded everything to fix it, I wouldn't have scrapped it. It had no right lasting as long as it did with the way I abused it with lack of maintenence. I have spent the last two years looking for a similar vehicle and they are all ragged out or bloody 4 cylinders. I have yet to have a vehicle last as long, even babying with all maintenence on time, etc. I hauled dirt, decorative gardening rocks (well beyond payload weight maximums), helped friends move, and crisscrossed the US in it multiple times. It saw 34 states and didn't leave me stranded til the end. Transmission finally gave up.

[@Ornelas11B]

@@AdamIsUrqed Yeah, that’s the thing about my truck, it’s in such good shape I keep fixing it. I’ve got over $15,000 in receipts in the last two years. It’s a gorgeous truck. It’s on my channel actually.

[@jamesinkeys]

Wizard, if you signed (autographed)the cover plate to the heater core, this will tremendously add value to the Jeep.. This, as a collector piece.. Subbed, and always a thumbs up!

[@CathyInBlue]

Sounds like an opportunity for an enterprising entrepreneur to develop a metal heater core for TJs that fits in the space of the stock unobtainium and lasts longer than a year.

[@ivycycles]

I dunno, I've found Rock Auto to be very reliable. I have one of their A/C compressors in my 240SX that I converted to R-134 myself. I also installed a condenser and radiator in my 2004 Toyota Sienna that I purchased from them. Never a problem. The access panel only makes sense. And since you are the ones doing it, we all know it isn't going to be a hack job. The factory should have done that to begin with.

[@dunebasher1971]

The reason the factory didn't was that all those extra panels, screws, seals etc would have added significant extra cost per vehicle. Absolutely no way the bean counters would agree to that for a part that usually has a lifespan of 10-15 years plus. And if you were doing it for the heater core, why not the evap core too? Again, even more cost for a part that rarely needs changing in the life of any given vehicle.

[@WhoThisGuy515]

Well technically it's not Rockauto's A/C compressor as they don't have parts of their own, they simply sell parts from hundreds of other suppliers.

[@mikerobbins5049]

I remember cutting a hole in a heater box inside a car of mine to replace a blower motor rather than pulling half the dash out. In the end, you could hardly tell what I did. The fact that I drove the car for many years so value at the end was of no concern....

[@samuelbeach5585]

In this day and age, always make sure parts are available for the specific repair before you tear it apart.

[@chrisminifie219]

Good point, but in this case if it leaks then it has to be removed even if there is no replacement; although you could just loop a hose to bypass the core. Now with the modification it can be dealt with quickly and cheaply once a core is found

[@talesofthecrypt-o4980]

Only takes a 1 min search on ebay to buy one.

[@PhilipMReeder]

I was watching a video on KZbin the other day about the USS Silversides, WWII submarine. It is a floating museum in Michigan. The tour guide pointed out that whenever a piece of equipment needed to be installed or removed from the sub that the hatches or other ports were too small for access, the crew would cut the pressure vessel open to make the exchange, then reinstall the metalwork with rivets and sealant. One hole cut then fixed was at least ten by ten feet at the top of the engine room probably to replace one or more engines. I saw this video, thought of Hoovie's Lambo and smiled.

[@TooBrokeToWheel]

Having done heater core swaps myself on vehicles that require removal of the dash I'm all in on this mod. Dash removal brings the suck bigtime.

[@ryanhorsley9965]

I actually think this could be a cool thing if the fabricated cover looks seamless. Burying a failure-prone and difficult to find part behind a dash is a far worse thing to live with. Too bad it'll be a hard heater core to obtain, which is unexpected and shocking considering how huge the Jeep aftermarket is.

[@rgbigdog]

An access panel should have been put in there by the design engineers when they drew up the plans for the Jeep.

[@robertf4540]

I think it's a great idea. Why the Hell didn't Jeep think of that?

[@dabandel]

Having had to replace the heater core myself twice in my 1997 TJ, I can totally understand this modification. Wish I had thought of that.

[@garyalford9394]

Also like a G.M truck fuel tank pump access cover! especially the way those things eat fuel pumps !!

[@davidhutchison3343]

My dad was a mechanic in England in the 50's, and a car came in with a leaking core plug at the rear of the engine. The factory recommended fix was to pull the engine out, to access the core plug. However, my dad told the customer they could do the repair by cutting a hole in the firewall, replace the core plug, then weld up the hole The customer did not like this, so authorised them taking the engine out. Once the engine was out, there on the firewall was a welded patch, right were the coreplug was located. The customer had the car from new, so a previous mechanic had obviously charged him for the factory repair, but had done the short cut instead.

[@johnkirkland3066]

Funny you mention that, I’m replacing all 7 expansion plugs on my 1999 Jeep Cherokee XJ right now. It has the same 4.0L as the Jeep in this video.

[@randybentley2633]

When other Jeep owners see this it may very well become a common request and as such Wizard, you may want to kit this up and make some side money. Given how mod happy some Jeep owners are the next buyer will see this as adding to the value of this vehicle. As to the core I'm surprised that with 3D printing being at the level that it is that there isn't someone making discontinued parts on request...

[@ChrisHendrickson82]

This isn't a hack job, this is reengineering. You implemented a solution to a known issue that should have been part of the original design. You very likely INCREASED the value of the vehicle, since any future owners aren't going to have to pay through the nose to replace the heater core.

[@playerroku4412]

No the value isn't increased.

[@TheBrokenLife]

Weird... My '99 TJ is still on its OEM core. *Fingers crossed*

[@keithmatthews1673]

I bet yours is metal and they later switched to plastic!

[@TheBrokenLife]

@@keithmatthews1673 I'll find out soon enough as the hoses are also OEM and should be replaced, well, probably 10 years ago. I kinda doubt it's steel, but we'll see. Really, plastic tanks _should_ be superior if the design was done well.

[@darlenegeorgeboyd8493]

When the fuel pump in my 1990 Suburban failed I wasn't going to struggle with dropping an almost full 40 gallon tank. I cut a just large enough access hole in the floor above the tank. Very easy to remove the pump that way. Sealed the hole with caulk and sheet metal. With the carpet over it you can't tell the floor has been cut.

[@TheFernando9431]

One of the perks of living in a tropical country (Costa Rica) it’s that if you have a faulty heater core you just by pass it by binding the two lines in the engine bay with a hose (A lot of cars have that mod, given that a chilly day here is around 15 degrees (Celsius) so a heater core here is mostly useless) But given the situation with the snow in the US and taking into account the amount of work that takes to replace the heater core, I would say that this mod is a great idea

[@jjlegend3922]

but why should it devalue the vehicle when its clearly something that should've been like that in the first place

[@derekwhidden9730]

Because is modified and no longer stock. There are people who are really anal about stuff like that, going so far as matching all of the serial numbers and nit picking the other parts.

[@tabbott429]

heater cores normally last 15 years or more if the coolant is maintained properly.. Its not THAT hard to change a heater core. I did mine myself without taking the dash out. Lloosen the dash and steering columne and pull it away from firewall on passenger side to gain access. swap and reassemble. THis is a silly request IMO for something that rarely fails

[@DL-ry3qg]

So you’re smarter than the car wizard? He could use you

[@mickmcnulty8200]

Why didn't you cut the firewall FIRST? If they wanted that done, You could have saved time and expense. Also, you say " replace every year" well if they are that hard to find, that will be a chore, and get harder.

Tell them to flush their coolant every 6 months and stop using cheap stuff. There's even anti oxidation agents you can add to the coolant. Having it recored is probably your best bet right now. My 96 XJ had a Tee installed on the coolant line over the engine for quick flushes and I'm impressed.

[@RJ-vb7gh]

After over 45 years of working on cars, I have found that the car manufacturer usually has a reason for almost everything they do. Generally that's why they hire engineers to design cars. Most of the hacks I've seen aren't thought through and in the end undermine the integrity of the original design. On the other hand, some of the engineering in modern cars is for the purpose of cost reducing the vehicle. In such a case, it's not a matter of mechanical or structural integrity that dictates a design decision, but rather an economic one. So, if done properly, certain mods can actually be upgrades to the original design. If the mod actually works as advertised, I might even pay a few bucks more for the car, knowing I can easily remove the heater core. My only concern is that you don't seem to trust your repair enough to warranty your work. I mean I've done emergency patch jobs involving duct tape and coat hangers, I wouldn't warranty for an hour, much less a year, some of which might still be driving around out there somewhere, but I've always stood behind any mods I've ever had to do, mostly on very old cars where the OEM parts weren't available anymore. If I design and install a modification, I don't expect anyone else to know what I did or how to fix it... I own it and I stand behind it, or I just don't do it. But it's your shop and your call.

[@davidt3464]

94 & older Wranglers its literally a 2 hour job to swap a heater core.. Once you've done it once.. ;) I have AC and I can still have the whole heater out in < a hour, while you have it out the first time you make sure the fan will come out from the engine side by trimming like 1/8" off the hole. Then the Chevy pickup fan fits and the heater will rock! the heater core in my 94 made it to 200K miles/18 years or so, I changed the coolant regularly.. The YJ core looks the same as that TJ..

It's quite possible that a coil company that makes heating/cooling coils for HVAC/R equipment can make a replacement coil if you send them the old one. Then ask for the copper coil to be made from a thicker HVAC type K copper which will last longer. All you have to do is braze on the inlet/outlet stubs with the heater valve or TXV valve. I have done this numerous times on older complicated HVAC/R equipment. Heatcraft is one coil manufacturer that I can name right now. Call or message them to see if they still have a coil building division.

[@chrisbreault5854]

I did a heater core in my 4.0 TJ . I lowered the steering column until it rested on the driver seat. I unbolted the dash , but didnt completely remove it. I actually suspended back as far as i could with bungee cords back to the roll bar. I removed the center console. I was able to carefully take the heater box assembly out in one piece. Thankfully i didnt have ac to deal with. It took 4 hours to remove and 4 hours to install. Backyard job. The heater core at the time was pretty cheap. I think the garage wanted $800 to do it. At the time i just didnt have the extra cash so i did it myself. But it was a bear of a job!
