I am interested in improving the airflow/ventilation inside a 2.1 watercooled Vanagon.
Has anybody put a vent in this position ?
Any ideas on how well in would work ?

Maybe as good as the factory vent, but with more work involved.
Two new pieces of glass, and a pair of vents, and you are good to go.....

It is too much work and it is a destructive work that might diminish the resale value.
As said better off the get the later model rear side window glass with the air vents and install them.

| I spent some time trying to find an appropriate pipe to go from the snorkle to the intake on my diesel vanagon (before a motor swap). I could actually still use the snorkle with my AAZ, though I'm planning to use that vent for an intercooler . . . Where did you get the pipe? |

I def agree with dobryan.
That being said... I am not entirely sure if the OP wants air to come INTO the van at that location or go OUT...
There seem to have been a LOT of conclusions drawn about weather that vent location actually bring "ram-air" into the engine compartment or not.
Personally, I would go with the late style glass/vent for air to pass out of the rear of the van. Even just one side would be way better. Some folks tell stories of how they or their installer have plenty of four letter word utterances while attempting the vent+glass types, but ALL of them rate the upgrade to air flow at top notch.

I drove my van for a while with a rear hatch latch extension in place. I know, I know, a grossly stupid thing to do with all those carbon monoxide fumes billowing into the van. Actually, I rarely smelled exhaust at all, but at times I did so quit driving with the hatch cracked open. When the hatch was open, though, the air flow was dramatically different. Instead of buffeting around inside the van, the air flow was laminar from front to back, making it much quieter, cooler, and comfortable. Since then I've daydreamed of some way to recreate this effect without brain damage, but (possibly due to CO inhalation) have been unable to come up with a way to do this with my skill set. All I can say is that it would be well worth it if a safe rear vent could recreate this interior air flow.

Watch the classifieds. The late model rear quarter windows with the vents come up fairly often. This will change your life, and not end it with CO poising.
Listen to dobryan. He's been about the most rocksteady poster I've paid attention to over the years. Always good info, and very encouraging. When I do something different at first, I often read back again on his comment, and when I do it right, its like night and day. (And that is why I will try, again, on the 'leave closet in' attempt on that window)

I understand what you are saying,but I didn't explain properly what I was thinking . I only used that photo to describe the position . On my petrol van the pillar is blocked off from the engine on the snorkel side .
I doubt while driving ,there would be fumes entering at that point, it is not much different to the window vents.
I was hoping some crazy person like me had tried and tested it before.
Just me thinking too much AGAIN .
I don't want to fall asleep at the wheel. |

the vents are in a LOW PRESSURE ZONE on the side of the vanagon.
set to allow the cooling fan little resistance in drawing in clean air to cool the originally designed air cooled engines.

That has to be one of the epic threads of that genre…similar threads made progress by halting steps but that one…? Not so much.

I agree with the OP, more air movement is needed in the back quarter of the van.
As others said, breaching the intake wall may introduce fumes.
One rear window was broken on my '86 when I first got it, so I searched for and found a post-87 vented rear window as a replacement.
A month or so later, I found a vented window for the other side and upgraded that one as well.
I'm still looking for a way to
1. neatly close the rear vents when it is very cold out and
2. duct air in through the vent with a 12v computer fan when parked/camping.

Yes, Volkswagen did it at their factory in South Africa:
But, for you to do it would probably be an engineering nightmare since those vans were built from the start to incorporate a dual-function D-pillar engine air intake/cabin airflow. So, I concur; easiest solution is to retrofit the (German) late-model rear windows & vents.

Plenty of scientific evidence was presented in that thread, but a few refused to understand it. Furthermore, within just 7 pages, a conclusion to the OP's initial problem was identified, regardless of the airflow debate: Oil cooler needed to be reinstalled. The "How does a Syncro/VC work?" thread is approaching 50 pages... now THAT is little progress with a lot of posts.

I want those sliding cargo side windows. Our Mitsubishi van has a slider there on one side and it's awesome cruising along with the air moving all the way through the interior on a nice summer day.
