That was yes, miraculous. My father had a few 1957-59 DKWs. At thirteen I started learning how to drive it. We had a farm with 20 acres and I drove it around for 3 years. I quickly took the decaying body off the frame and drove it like that. Fantastic fun!
The principle of cooling is called "thermosyphon". I would only use distilled water in the system with appropriate aniti-freeze mixture. I never was alerted to any problem with using antifreeze when I owned two of these and had no cooling issues whatsoever.
@@christianschneider880 Could be but with anti-freeze, I don't see how corrosion would be an issue. I was a motorcycle mechanic and our dealership was directed to use distilled water in our two water cooled machines (Suzuki GT 750 and RE5) due to the small aluminum radiators and aluminum engine blocks - my recommendation is on that basis only. We were instructed to add leak sealers at the time of set up also.
@@whalesong999 Dear whalesong, of course use antifreeze, its clear, so I didnt mention it. Here we are maintaning 60 years old engines. They arent made from Aluminium. I Always use plain water with antifreeze.
@@christianschneider880 We're on the edge of being a bit snippy with one another, I hope that doesn't prevail. I mentioned my experience with the motorcycles only as a point of view, not not admonition of another's choice. I'm sure that distilled water was indicated because of sediment in tap water and how, over time, it causes problems. I once had a Datsun 510 who's radiator eventually clogged from using tap water - I'd bought it used and proceeded to put over 200k miles on it. I just saw good reasons to stick to purer water.
@@whalesong999 I dont intend to teach everybody with my "wisdom", and I dont make a religion which water should be used here or there. Everybody has his free choice. Perhaps at Aluminium engines distilled water has better results, especially at long maintainance periods, and it will not be dangerous. Normal water is less aggressive at iron and steel. I always use it.
I had a Kubota that was cooled in the same manner as your DKW and Kubota specified a 50/50 mixture of coolant and distilled water. It cooled well with that mixture with no problems.
this is an truthfully amazing car! here in Brazil, those used to be extremely popular in the 50s and 60s, until VW bought DKW (here we pronounce it"DKV"). great car, runs like a champ!
I wonder if rust debris inside the coolant jacket isn't the cause of your overheating issue with anti-freeze. Not real familiar with that type of system but I have found a real good system flush works wonders... I once pulled pounds of rust particles out of a used engine. I couldn't believe how much was in there.
A good solution for a nightmare problem. But what were the original engineers thinking when they placed the bolt in the fluid? The housing should have been held in place by two bolts on a flange outside of the housing into the engine casting. Also, maybe more antifreeze can be used if Royal Purple Ice is added to it to increase heat transfer. Have you considered adding an in-line electric water pump to the system?

Distilled water I dont recommend. Causes even more corrosion.

For future reference, left-hand spiral drill bits are available and are brilliant for removing sheared bolts/studs.

In German it's pronounced like "Dee-Kaw-Vee".
@@douro20 yess! haha amazing to know, always thought it sounded funny, now I know why it's pronounced "v" instead of "w" :D
That is such an awesome looking car I like it every time I see it in your video's.
A labour of love, that's for sure. Waiting for the follow up video.

I know it's too late but a stud in instead of the bolt. Brass nut on the outside. Really enjoy your videos.
Would it be possible to add an aftermarket coolant pump to the system, if there is such a thing.

Yep I know.
Great work!
I need some vise grips like that!
I love this car, you have some really cool cars
lady luck was on your side that day!
Cool looking car, too bad it does not have a pump but like you said a Stainless steel bolt will likely fix that for next time.
Why would you use the oil injection when ya can block it off and pre mix?
Your kids must love you.,...all those toys!!!
do they make a stainless steel bolt? So it won't rust?
hi i seen whatu r capable of,pretty sure u can adapt a pump,loocking ahead to dee it ,thank u
Are those real dollar bills under the clear coat or just painted??
you're a hero! nice one!
Beautiful car … Like !…
Is it real money in the top
lucky..
Was für ein Drama wegen einer abgerissenen Schraube?
Jeder Bastler hat da eine Lösung!
cool
