Now I understand how they work! It makes perfect sense now! They were very clever. I can appreciate that it would work better to repair the original than to put a lesser quality repo in its place. Thank you for sharing!
I was thinking of restoring the original ones on my 63 bug since they are still intact and just have surface rust. I was considering soaking them in white vinegar for 24 hours, would you say that’s safe and won’t damage the heater boxes? Let me know thanks
This may be why I’m always getting oily film on my windows after running the bug. I’m guessing exhaust is passing into the heater box and getting inside
@@Mikefngarage my 63 has a later model engine and setup. It has the fresh air heater boxes . I don’t understand why the film on my windows. Unless there is a leak in the fan shroud and pushing oily fumes?
Thanks for making the video. How would you know if you have a carbon monoxide/exhaust fume leak? The heating system seems ingenious and I want to hook it up but worry about getting exhaust/carbon monoxide in the cabin. Also should I be concerned about getting fumes into the cabin from the lid that covers the engine? It seals well and have it covered with carpet and a rubber mat. Thanks for any info and advice!
Usually you can hear an exhaust leak on the fresh air heater boxes like this one in the video. Then you should be concerned about carbon monoxide. Usually on my old Stale air car I keep the window cracked. to get some fresh air just in case.
I just bought a 68 bug in bad shape that came with lots of parts. I have 3 or 4 of these, and now I know how to fix it, thanks man. Damn, I dont have a welder. Im pretty sure my box is full or I would get one. Guess I may need to upgrade my circuit. You should do a video of the actual repair. Do you cut the rusted flange flug and insert this one into to it?
the aluminum is fused to the steel pipe underneath. Welds great with regular mig welder. Done this repair for 40 years no issues. I normally leave more of the steel pipe. He welded it a bit close to the aluminum IMO. but it still worked.

Thank you for posting. I'm about to repair/replace my heater boxes and this is one of just two videos on the subject that I could find on youtube.

How do you fix the outer heater boxes when they are rusted??
I have a 58 goggomobil with the same idea exhaust. I really wonder if they were talking to Porsche at the time.

Stale air heater boxes do that. 61 or so and earlier

I usually fill the internal J tube with water to see if it seeps out
@@Mikefngarage where do you listen to it at?
@@shrimp562 make sure you have no exhaust leaks and if everything is tight and you still hear loud exhaust then your heater box might be bad.
one guy said fill the heater box with water and start the engine. should blow out of there bubbling. Might not be a bad idea. @@shrimp562

harbor freight has a good 110 welder the titanium great investment for fixing stuff
Hey Mike, my son has a baja with bazooka header/exhaust. Winter is coming and he wants to know how to reattach the heater boxes to his new headers.
Thx man! Was about to throw mine… not anymore!
Hey Mike . What kind of welding exactly you used to weld aluminium and iron for this heater box repair,great video by the way .
the aluminum is fused to the steel pipe underneath. Welds great with regular mig welder. Done this repair for 40 years no issues. I normally leave more of the steel pipe. He welded it a bit close to the aluminum IMO. but it still worked.
Well , you have definitely have done a fantastic job,thank you .I give this 200% job well done.
Good to know thank you!!
thanks
Why not make them out of cast iron = lets ask Ralph Nader ................................................Me I like Corvairs
