Hi, I know this is kind of an old video but I just wanted to say I really like how you explain everything for beginners, especially tricks like this for people who don't have special eqipment or a lot of experience. I don't have a welder and have no clue how to even weld! I have a 1972 Super Beetle I'm trying to restore. I'm completely new to this and I'm working on it a little at a time the best I can. Your videos are definitely going to be a big help!

[@SladesVWBeetle]

@@ct92404 thank you very much for the kind words. I always hope these videos help other folks out that with this channel is all about. And I’m glad to see it has become a big hit.

[@suzukiman650]

Ain't stupid if it works. A nice budget oriented repair. Heater boxes are not cheap.

[@SladesVWBeetle]

Thank you my friend! I try to do budget fixes when possible.

[@kyridgejumper]

Not stupid at all we can all use helpful videos like this Great topic

[@SladesVWBeetle]

Thank you my friend! I truly appreciate that.

[@TheJorgSacul]

Just a comment on the durability of JB Weld-- I had blown out part of an exhaust manifold gasket on my 70 Maverick and it was loud as hell. I didn't have the finances or tools to pull that manifold off and re gasket it so I made a "roll it up into a worm and stuff the gap" patch with JB Weld, and that sucker held for 10 years with no issues whatsoever. Hot summer/cold winter, never loosened a bit under full engine exhaust pressure.

[@SladesVWBeetle]

Oh I believe that it worked quite well jorg, honestly I love JB Weld. I have used it for multiple things. If I showed more budget videos on everything I did with JB Weld, I think everyone would be shocked lol I hope you’ve had a great day.

[@beetleworks738]

I got 2 heater boxes that came with Lucy when I bought her so I see project in my horizon

[@SladesVWBeetle]

Heck yeah, get them on her!

[@apodaca309]

Kool trick our 78 Arizona convertable will be toasty warm in winter time in El Paso. Thank you

[@SladesVWBeetle]

Thank you for taking the time to leave a comment. It’s a cheap fix instead of buying new heater boxes when needed. Everybody is too quick to put new parts on all of the time. Thank you for being here.

[@heathdelzell9547]

Awesome! I was really struggling to spend $500 on heater boxes when I bought the bug for $1,500!

[@johncollins5552]

The new heat boxes make much less heat because they have less fins inside, also would bet my house they won't last half as long as the originals did 30, 40 years plus!

[@SladesVWBeetle]

I am glad you enjoyed the video, I like to do budget fixes when possible.

[@SladesVWBeetle]

Thank you, I truly appreciate it. I hope you have a very merry Christmas.

[@jacquelinechellis4036]

Thanks for video its a good fix. I think theres a high temp jb weld or the regular jb weld handles more temp. Maybe header paint also. It can last a long time. Have a good one.

[@greggbrown0]

I’ve used JB Weld on holes in my oil pan😁

[@SladesVWBeetle]

Honestly it does work! They even sell an extreme heat JB Weld. That works quite well.

[@RaymondLohengrin]

I have a 1971 Super Beetle. I learned this from a friend while working on rebuilding real airplanes. If you want Epoxy, fiberglass or JB welder to be glass smooth without sanding, place a piece of wax paper or packaging tape over the material while it is drying and use a piece of plastic or old credit card to press down and smooth out the material. Once the tape is removed the surface will be smooth as glass. I have used this over Bondo multiple times and it really saves time as it also helps molding the Bondo over the surfaces. Great video, thanks!

[@SladesVWBeetle]

Thank you Raymond! I appreciate you chiming in with extra tips. Oddly enough I did try that once with Bondo, I put wax paper over and slightly greased the outer side and smoothed it out by hand. It really made a huge difference! Much less work after that. Merry Christmas my friend.

Thank you very much Jane, I truly appreciate the kind words! I just try to do what I think is right, and help others. I also created a Facebook group, slades VW community. It’s been a lot of fun so far. Don’t forget, to keep check on the community tab here, sometimes on Friday nights I have a live chat at 8 PM Eastern time which is a lot of fun. I always announce it on Thursdays here.

Great Job!!

[@SladesVWBeetle]

Thank you!

[@randall1959]

Doesn't apply to my car but still plenty of good information. You're right. When you have everything in good working order you'll have plenty of heat.

[@SladesVWBeetle]

Thank you Randy! I hope you have been enjoying this cold weather, we got hit hard today.

[@brucegillies1694]

I originally drove a VW for economic reasons , then because they were so fun to drive , but I still look at low cost per mile , i'd like to save money also !

[@anthonyconti9755]

Great info! Love your chanel. You explain so well. Thank you. Ive been watching and just started working on my 1974 thing. Im really learning alot.

[@Erik_Swiger]

I had a '68 Beetle, it was my first car in the early 80s. The heater boxes were, of course, rusted out. There was a street that would pool with water whenever we had a heavy rain, and I would fly down the hill in my Beetle and hit the pool of water and just skate across it. Then my windows would become absolutely covered with steam from those leaky heater boxes. I had a total of 5 Beetles, and I really want to own one again.

[@SladesVWBeetle]

Hi Erik, theres a few on the marketplace, and craiglist. I do so love these cars! I truly hope you find one. I did a few videos, on what to look for on them before purchasing!

[@newalex1970]

Great video !!! I noticed today that my heater boxes had a few holes . Keep up the great work big fan !

[@AngelRosario]

Great idea! Don’t know if I have holes in mine but I’m definitely going to check and follow this 👍🏿

[@wingsonmyback1]

[@SladesVWBeetle]

Thank you, I really appreciate the kind comment. I’m glad the videos help other folks out. We’ve got to try to save money when we can.

[@DWaugh]

Great video. Thanks for taking time to go through the heating set up and how air moves through the system.

[@SladesVWBeetle]

Thank you Darren! And I hope you have a very merry Christmas.

[@jimo199966]

There are (thankfully) a lot of VW channels on KZbin. I enjoy yours because of your humor and how thoroughly you explain things and show it. I just bought the 25th anniversary of the late John Muirs "How to keep your Volkswagen alive" because of the inspiration from channel owners like yourself. I don't currently own a VW, but my first car was a 1960 type 1 (20 percent Bondo 😆) and I'm thinking maybe I'll find another type 1🫰. One can hope, eh? Btw, what (if any) year did the factory add a blower fan for the interior HVAC? Thanks for the content and time👍

[@dwaynemathias3834]

If a VW heating system is intact it works great. I have a 78 and it will sweat you out and it's a convertible, and for most old convertibles the top doesn't seal like it did when it was new.

[@SladesVWBeetle]

Absolutely! They do heat very well. I think some folks that are not familiar with the system, tend to think they don’t work.

[@TinyHouseHomestead]

Use "coarse" fiberglass cloth, it works better! 😁👍👍🇺🇲

❤, great idea. Makes sense to me. Some times it’s the simple ideas!

[@cjjones1556]

Of course that was a great tutorial. Not stupid at all. Cheep AND effective. I do love the new microphones. Your audio is so much cleaner. Glad you are using the towels that I threw in with the wheels. That was my small contribution to Heather. Channel Idea: you guys like your old movies. Do a spinoff of Mystery Science Theater 3000 except with your old movies. Peace Y'All and Merry Christmas 🎅🤶

[@SladesVWBeetle]

Heather seen the towels, and said… my goodness what have you started with everybody lol she said there’s going to be wives coming after you. Lmao!! We love old movies, still gathering as many ideas as possible for our channel together. I’m really excited about it. I hope you have a very merry Christmas.

[@davidryan573]

jB weld is great, makes sense. My opinion on the second channel is, do what you two are passionate about, whatever that might be, cooking, DYI , travel, I think that’s why Your VW channel works, you can tell You really care about VWs and it’s a passion.

[@SladesVWBeetle]

Thank you my friend I truly appreciate your opinion on the next channel. Or should I say the extra channel lol we are definitely writing down ideas I think it will be a lot of fun for us to do it together. I hope you have a very merry Christmas.

Not stupid at all, it will be of great help for a lot of folks. You did a great job and thanks for sharing how you did it. Another way you can go and this is what I did, I looked into Facebook marketplace and you will find somebody selling the heaters. I bought a nice pair of heaters for 70 bucks, included one carburetor, air filter, heater hoses, alternator, and piston tins, all for 70 bucks. So keep searching and you will find them.

Really good information. Mine doesn't have heater boxes, the previous owner either took them off or changed motors. Not too imprtant down here in South Florida. If we do have a cold day I just bundle up or wear an extra shirt. The audio was great no background noise at all, use them on the livestream. See you Sunday.

Good ol JB weld to the rescue! Used it for years.

[@larrymcgarage2152]

I had the JB weld concept, but didn’t know about leaving the pipe loose at the ends. Looks like it would loose a lot of air around those openings, but I get it. It needs to expand and contract. Thanks for sharing. Another great video as always. Merry Christmas to you and Heather.

[@SladesVWBeetle]

Thank you my friend! I hope you have a very merry Christmas.

[@Erik_Swiger]

It's controlled leakage so the heater boxes don't melt when the heat is turned off to the cabin.

[@larrymcgarage2152]

Thank you.

[@SladesVWBeetle]

Thank you Larry for always being here!

[@dog01b52]

Good job on patching video, sound was excellent. I use popsicle sticks to mix my JB weld and acid brushes to paint with. They are cheap and can throw away when done. I just mix the JB Weld 50-50 and what's left over on the cardboard, usually smudges, then leave the popsicle stick in it to test how it has cured up. Paint to preference, I used gray paint. Now my Dad's VW heater boxes, the J pipe, are both all rusted out. That would be another video changing that out.

[@SladesVWBeetle]

Thank you so much my friend! OK I didn’t think of that, I’m going to grab a pack of popsicle sticks since I use stuff like that a lot. That was an excellent idea I so appreciate it! Plus I think Heather has a bunch of them in her craft room lol I hope you have a very merry Christmas.

[@SladesVWBeetle]

Thank you very much my friend! I definitely would have showed it if they were still on the car for sure.

[@khaledrawashdeh4934]

I started cleaning the heater boxes and ended up dismantling them down... I thing they will look and perform much better after I repair, paint and assemble them. Thanks for your inspiration.

[@boatshaughie2841]

i don't have much use for boxes ,i live in Fla but I'm doing a Ghia convertible and maybe could use the heat a few times a year

[@SladesVWBeetle]

I normally don’t use them, especially with the engine that will be going in next. I can’t afford the larger sized ones. Plus I rarely use heat, I hide my car in the winter lol

[@johncollins5552]

Cool, yours were in worse state than mine, mines a 72 standard 1200 so it's newer I guess. I have a couple of pinholes and was gonna plug them with JB weld but your technique looks a better option.

[@SladesVWBeetle]

Thank you John! It’s a budget fix that honestly works very well I have done it quite a few times. They also sell extreme heat JB Weld but they didn’t have none at my local store.

[@smonroeh]

I've used JB weld for body repairs and 4 wheeler/quad engine case oil leaks. I would probably use the regular not the quik version though. Takes a bit longer to harden, but I've heard that it's a bit stronger too

[@SladesVWBeetle]

Absolutely I agree! That’s all I had on hand. I was trying to find a high heat JB Weld but I didn’t see any at my local stores. I think it’s called extreme heat.

I’ve used the jb to fill holes in expensive mufflers. You have to wrap it though or the jb will not hold.

[@SladesVWBeetle]

JB Weld is a good product, I never realized how many different things they do sell.

[@MikeMoose67]

Now that was a fantastic video my friend. I was shocked how much they charge for new ones.. And no that was not a silly fix when most folks just wrap them in heat shield muffler tape . Great job I think they may last much longer than what you expect. You and Heather should interview each other. The Slade community would love to hear your story

[@SladesVWBeetle]

Thank you my friend! I try to do budget fixes one possible. It really makes a difference. I’m testing out metal Bondo, but I don’t think many people will find I’m using lol and thank you for the tip on our next channel together. Or I should say or second channel.

[@gordondonahue4810]

What about you and Heather doing a home project channel. Every week feature a different task. Home repairs on the DIY scale. In the summer do outside things. Wintertime focus on the inside. Just keep things small and manageable. 😊

Thank you Gordon, that is an excellent idea I will bring up to Heather. We definitely are going to have a second channel together I think it will be a lot of fun! I hope you have a very merry Christmas.

[@brockreid1]

A project I am curious about would be taking stock heater boxes, cut open the *shell* and somehow swap out the inner *J* pipes and upgrade to 1 5/8ths *J* pipes to match a 15/8 exhaust headers...a save $$$ on those aftermarket big bore heater boxes!

[@SladesVWBeetle]

That would be very interesting to do! I know they sell the larger diameter heater boxes, but as you said they definitely are not cheap.

[@VWBEETLEOVAL1955]

well JB weld is a very good alternative for fixing those kind off problems. you can drill holes in it and even tread it for a bolt. very strong stuff. what i didn't know that it would hold on to rust. a great outcome for way less money like new once. well done my friend. a new channel with Heather? great idea and would fun to see.

[@SladesVWBeetle]

Yes that JB Weld works quite well. I was trying to find the extreme heat JB Weld, but I couldn’t find any local to me. I hope you have a very merry Christmas my friend, and we are very excited about opening a second channel together.

It looks like it would be hard to work on those vent hoses that are hiding in the pillar area were one goes down and the other one goes to the heater box that provides to the windshield vents

[@weirdrepairs4658]

I bought some used/new heater boxes locally for $120

[@SladesVWBeetle]

That was actually a very good price Wyatt, I try to check the marketplace once in a while for things like that.

[@SDsailor7]

There is a product that neutralizes rust and is good to use before painting those heater boxes.

Would you use rust conversion before prime to stabilize the metal?

Those heaters are good candidates for a sand blaster.

[@ggolds5]

My heat works as it was designed. No issues with box's etc. Or fan. My question is.... there is a good amount of heat going through the vent on the floor between the front seats to the rear of the Bus. I was wondering , is there a way to stop the floor heat to the back and get MORE forceful heat to the front vents between the headlights / kick panels. Can the floor vents to the rear be blocked or redirected ?. 76 Bay camper. Thanks.

[@damian-oq7hl]

Great video and your mic provides great audio. I'll be working on the heater boxes from my '72 Ghia this weekend following your recommendations. I'm curious, why do you advise not to JB Weld the internal 'J' tube to the external shield of the box? Thanks in advance, keep up the great work. See you on Sunday.

[@SladesVWBeetle]

The heater box shell, and the J pipe tube, are not attached together. When you bolt the J pipe on, the outer shell sometimes will need moved slightly to hook up the hoses. I don’t believe they’re hooked up from the factory either. As one piece. I hope that made sense. Going to be live tonight with heather since Christmas is Sunday I’ll see you at 8 PM Eastern

[@mikemcleod7816]

Is there a way to repair/rebuild the valves at the top? My daughter and I are fixing up our first bug and your videos have been god send.

[@SladesVWBeetle]

Thank you I truly appreciate the kind comment. I’m so sorry but what do you mean by valves?

[@mikemcleod7816]

There is a flapper valve at the outlet end of the heater box. The flap is not seating and looks like a spring may be broken inside @@SladesVWBeetle

[@LouKodge]

We dont have JB weld in Australia. Can anyone tell me What an alternative product could be please.

[@SDsailor7]

How do you lubricate the flapper valves on those heater boxes? do you use grease? or nothing at all?

[@donaldboisvert1602]

Thank you for this video. My Daughter has a 1968 VW bug. I am trying to help her get heat into it. MY QUESTION before going through the trouble of this repair. is there a method to test the (J) channel that it is not compromised allowing exhaust fumes into the cabin?

[@SladesVWBeetle]

You’re very welcome and thank you for being here. This is the method that I would use. Just cover one end, with tape, and then maybe find a friend that vapes? Unless you have some type of smoke machine. And blow smoke in there, and try to watch for it to escape out of the J pipe inside. Looking through the shell. I hope that made sense

[@superveganwhat]

Very helpful tip/how to video. When you were saying that the pipe inside the heater box is essentially just a J tube Is it the same inner diameter as an aftermarket J tube. People on the samba and VW Parts distributor seem to suggest that inch and three eights J tube which fits into the stock muffler are somehow bigger than the J pipes inside the heat exchangers Or somehow flow better than the heat exchangers do you know if the heat exchangers exhaust pipe is inch and 3/8 or of the same diameter as the typical J tube for an inch and 3H exhaust system?

[@SladesVWBeetle]

Thank you for taking time to watch the budget video. I like doing budget fixes when possible. I’m not quite sure about the size of the heater boxes vs the J tubes that are aftermarket I will have to look into that. I’m going to run a 1 1/2 inch header, and I know they sell one and a half inch heat boxes but they’re too expensive for me.

[@davidbrazee6336]

I don't presume to know more than you, but a question. Why didn't you use a rust converter before the repair? You just removed surface rust, I've always been told if you repair over rust, it won't last. Thanx

[@SladesVWBeetle]

Hey it’s all good! Using Ospho is what I normally use! So yes!! Great idea! I was basically just showing a cheap fix for the holes. But….yes!! You’re right!!

[@davidwhocares3293]

That's a great fix ! At about 25:30 You mentioned not to seal the shield to the pipe that clamps to the muffler....why is that ? You said it needed to move a bit freely there ?

[@PunkRockerDad]

Yes I have this same question

[@SladesVWBeetle]

Moves slightly a little bit because you’re hooking those hoses up to it, which if it was welded to the exhaust J-tube it would not be able to move around to hook up your accordion style hose, and the adapter that comes from your ductwork. I hope that made sense.

[@martinstachurski4712]

Thort it would lose olot of hot air at the ends thort you,d have to seal

[@PunkRockerDad]

I’m getting exhaust/CO in my ‘67 bus which has a unique RH side box (with a port for the carb pre-heat tube) so repairing the existing is a win…but the CO has me keeping the heat off. I’m guessing this means one of the “j-tube finned” inner components has a crack? What would people think about a JB Weld patch (assuming I find the leak)

[@SladesVWBeetle]

Honestly my friend, I would not be messing around with that. Unless you absolutely can find out where the crack is and repair it. Please leave your heat off until you do that. That would be the inside J tube finned area that must have a crack in it.

[@PunkRockerDad]

@@SladesVWBeetle yeah it’s off. I got a battery powered CO detector on board too. This bus had some aftermarket dash fans and I’m pretty sure at one point had one of those Borg-Warner gas powered heaters too. I’m looking to restore the OG heating

[@frankschwartz7405]

If you want real heat in a Beetle, do some plumbing and install an oil cooler under the dash. Or put it under the hood ahead of the dash. You could probably even rig up a fan and ductwork to the defroster vents and floor. You would need two coolers, one outside the cabin for warm weather use with a diverter valve.

[@shaneabel9976]

There used to be a company that made some high CFM fans that went in under the rear seat. It was a full kit, and pretty nice, from what I saw when my friend installed it. The beetle still wasn't "hot" inside, but you didn't have to drive with chattering teeth.

[@soilmanted]

I can't imagine the need for any sort of auxiliary heat. Maybe in some older beetles, which had an older style of heater boxes, but my 1968 Beetle, with heater boxes like those shown in this video, had the best heater of any car I've ever had. Engine warmed up quickly (thinks to the thermostat) and the engine started blowing a huge volume of painfully hot air into the passenger cabin. Kept the cabin 80 deg F when it was -10 outside the car - even as the car aged and the heater boxes began developing holes. I am at a loss for why anyone thought these vehicles did not have good cabin heat. Even my VW van had plenty of heat and its passenger and cargo area was much bigger than the Beetle. Now, I saw some air cooled VW's where the wire cables that open and close the hot-air flaps in the heater boxes, were either unattached, or were attached improperly, so of course the cabin did not get heat. But this was not the fault of the design of the car. It was the fault of someone who repaired or maintained the car improperly.

Yah ... right .... Running oil up under the dash.... Clearly ... getting quality medication is an issue ..... How do people come up with hair-brained ideas like that ?

​@@frankschwartz7405 I was mistaken, you don't need better medication ... You need to knock off the crack ! Oil cooler bwahahaha .... If you knew even the simplest of things about beetles ... you wouldn't suggest such silliness .... 😂

[@brianlewis6926]

How long does it take for it to get warm inside the car, I never have experienced one that worked good, Could you wrap it in exhaust header wrap

[@SladesVWBeetle]

I never tried to use header wrap on a heater box. I think it might be a little difficult. With the shape of it. I usually was nice and toasty within 10 minutes with Volkswagens that are air cooled with heat boxes.

Thank you for always being here my friend

[@davidgrason161]

Great video! But I have a question: At 25:09, you tell us that we shouldn't..." let this stick to this" meaning that the outer shell of the heater box should not be fastened to the inner j-tube. Then again at 25:27, you state that the outer shell should not be glued to the inner exhaust tube. You say that this inner tube should be able to move. What is the reason for this? It seems to me that those places could let warm air escape? What am I missing?

[@PunkRockerDad]

Tagging along here as I have this same question

[@SladesVWBeetle]

What I meant is the outer shell should be able to move slightly. The inner J tube to bolts up to the engine and exhaust system, and stays stationary. The outer shell, the part that we repaired. Moves slightly a little bit because you’re hooking those hoses up to it, which if it was welded to the exhaust J-tube it would not be able to move around to hook up your accordion style hose, and the adapter that comes from your ductwork. I hope that made sense.

[@ct92404]

...I do have one question though, is there any problems with carbon monoxide getting into the cabin if the heater boxes are rusted like this? I though I read something about that one time.

[@SladesVWBeetle]

@@ct92404 if you have holes in the J-tube, inside the shells, then you will definitely get fumes into the cabin. This fix is only if the outer shell has a little hole. The J-tube inside is what’s important. Let me know if that makes sense to you.

[@ct92404]

@@SladesVWBeetle It does make sense, thank you. I probably just won't connect the air ducts that go from the heaters to the cabin until I can test for sure that it's not leaking fumes. I live in California, so I wouldn't need heat that much anyway except for maybe mornings during cold weather. But it's going to be a long time before the car is driveable anyway! 😂 It needs a LOT of work.

[@adamsrescuesvws9504]

Where can I get the auxiliary fan

[@SladesVWBeetle]

Honestly, I would punch that right into Google and you’re gonna find numerous places more than likely. But I want to test out is one of them diesel heaters. That they use an RV they’re pretty small. I think I’m going to do that over the summer. And then I won’t use heater boxes.

[@adamsrescuesvws9504]

@@SladesVWBeetle ok my beetle has one of those gas heaters but I not sure how it will work

[@NRYT2360]

"box under the front hood" @7:00 ?? what box and what does it do?

[@SladesVWBeetle]

That would be just a fresh air box. It grabs outside air through the vents, when moving.
