Doing air to water, thought....
why not mount smaller motorcycle rads into the rear air intakes and not have to run the WHOLE system up front.


Thoughts?

Have you analyzed the capacities of the radiators you are considering and the multitude of connections necessary vs the stock system? I think dual radiators in the D pillars is more complex.

Not with smaller radiators, but with full size rads, yes.

The vanagon radiator is huge, way oversized, but it's in the front for good reason, to get full-on air blasting it.

If you were to put it in the back you'd want to take that into consideration.

Local samba innovator/genius Andrew Flint set up a bay window bus with a 1.8t and the rad towards the back/underneath I think.

You can see it under his bus on page 8 of the following thread.

I believe that the volume of direct cooling air of the forward-mounted stock Vanagon radiator arrangement could not be matched by smaller radiators tucked out of the direct air stream in the rear vents.

Especially considering that there has been much debate, and no small amount of lively discussion here, as to whether the Vanagon D pillars serve to EXPEL hot engine-compartment air upward, or to DRAW IN cool exterior air downward.

The subject remains as contentious as the transubstantiation of bread and wine ...

Do the simple math. Measure the length and width of the Vanagon radiator.
Are you going to be able to have the same square inches from motorcycle radiators the fit into the rear air intakes?

As for putting a radiator underneath is it going to be laying flat where a rock or stick can put a hole in it?

Is the purpose of doing this to eliminate the long hose runs or do you have something you want to use the space where the radiator fits.
The original location works.

If you have a tintop, buy a Westy roof. Just lay it on top of your tintop. Modify it so it becomes an air tunnel with the radiator at the back, on the roof above the engine.

Busaru.com did it in one of his YouTube videos if I recall correctly. Two Honda rads rings a bell.

Well, that was a fascinating distraction. What a great build. Other than Vanagons and classifieds I don't visit much else at the samba so threads like that help me get out of my shell. Neato.

The very first Vanagon engine conversion I ever heard of was in Australia and it used 2 radiators in the rear pillars.

I’d probably just go with the front because with all factory parts, it would be easier for me with my (lack of) skill set. 😄

I remember seeing a Vanagon in Port Townsend a long time ago with a radiator attached to the left rear of the driver's side!! Pretty sure it was one of Scott's early Subaru swaps.

I wouldn't be comfortable having my radiator in such a vulnerable position.

Samba member furrylittleotter did it with his Subaru swap.

https://www.thesamba.com/vw/forum/viewtopic.php?t=558965

I just read thru it again. He got a lot of flak for really no reason. Probably why you don't see some of the true innovators stick around too long.

Too much of this...

I said it in 2017 and I'll say it again, the first post in this thread is easily one of the most interesting posts on the samba I've ever seen...

I also really liked his Vanagon proboscus... https://www.thesamba.com/vw/forum/viewtopic.php?t=...mp;start=0

As I understand it, furrylittleotter sold his super-modded Vanagon a few years ago.

He did have a "straightforward" way of interacting on this site which led to interesting exchanges around his unusual ideas as well as mods he didn't like (he had a spirited distaste for everything bostig Very Happy ).

Neil was VERY abrasive - so much so that even those of us who were open-minded and interested in his ideas found him hard to take.

As an abrasive sort myself, I can tell you what he lacked in humor, he made up in out of the box thinking. Humor is the key to bludgeoning folks with your aggressive opinions. Someday I'll develop a sense of humor, and I'll rule the world. Until then, I'm stuck here with you idiots. FML

I guess the main reason not to engineer a new system (when the stock parts are readily available) is that it might not work well. You will also very likely have more time and possibly more expense into getting it to work well.
