In addition to what Chris said, you can send air to the rear of the van by moving the 'Rear Vent' slider (the one on the bottom) all the way to the left.
Close down the 'Defrost' and re-route the air towards the back seat.

| True that, it just doesn't have that much of an effect, at least in mine. |

Just ordered the fresh air kit. I will install it on my next CA trip - along with some nice Burley items  |

Here's a look at my newest product. I've adapted a high-quality brass ball valve to be a direct replacement for the aged plastic OEM valves that leak internally and don’t stop the heat. Plus it will automatically and constantly purge the radiator.
More here:

I'll have this out pretty soon, check the Vanistan shop for price and availability, and thanks so much for everyone's support!

| Bravo, Chris. Always love seeing your inventiveness. The self-bleed feature is a great idea. |

The self-bleeding feature in itself makes it worthwile! I love the idea. A couple of questions:
1 Where does the air go when bleeding? If the tubing sends the air back to the heater core, doesn't it just go back inside the coolant circuit somewhere? Or is it rerouted to the expansion tank?
2 I thought a minimal amount of coolant passing through was necessary, even with the valve closed. A very small amount wouldn't heat the core much, but allow coolant flow and hep prevent corrosion.
Looking forward to see the pricing!

Does the clear hose evacuate air from the top of the rad back into the coolant flow to burp in the coolant tank?
Self-bleeding is a bit of a mystery to me.
p.s. it looks so pretty I might buy one to hand from the rear view mirror.

Exactly. it's patched into the heater return flow, which is at a lower pressure after the heater core than pressure at the top of the radiator, and if you close the heater valve, the difference is even higher. So coolant is able to fill the radiator to the top without the air there pushing back, and the air flows out and down to the heater return hose and gets purged back at the pressure tank like everything else.

That's a popular myth, one of those rationales people come up with for what they think they're seeing, but they usually haven't actually looked. If you examine how the OEM valve was built, it definitely closes 100% by design. But it uses a rubber seal inside to seal around the nylon ball, and the seal ages and gets little cracks where it meets the ball, so a little coolant is always able to leak thru.
Even that tiny amount does heat the core unacceptably, when the weather's warm, it's what people have been complaining about for years. I had a valve that closed perfectly since new but started leaking last fall. It's not even fully spring and the minimum heat was already intolerable on a warmish day. But that put the fire under my ass to get this done, I'd already clamped and unclamped the heater hose enough times, and I know the replacement valves on the market are kinda hit or miss.
Corrosion from stagnating coolant is a real thing, but that's a very slow process, and the designers would never consider that the heater valve would not be operated for years. Besides, we might wish the cars to last forever, but they most certainly did not.

There's entirely too much thought going into these products. Please dial it back a bit. Excess thought makes me nervous.

If that's PVC tubing (e.g. Tygon) I'd be worried about the the heat/pressure getting to it. Is that an issue?

Yeah, I thought the working temperature of clear vinyl tubing is around 150-175F. I think for a vanagon any tubing needs to be rated to at least 250F to be safe.

Thanks Casey, but you can relax, no excess thought, only what's needed to build it right, which by mind-numbingly obvious necessity includes choosing the right materials.

| Definitely looking forward to seeing the cost. I know it will be more than $9 but hopefully under $150. |

Beautiful work on the valve!
Will definitely be purchasing this, thanks Tencent! |

Yes! I can use one of these. I've been putting off replacing mine because the replacements are crap. My diesel runs cool enough where some increased flow to the heater core would be welcome. I'm sick of crawling under van to work the ball valve I installed as a work-around! Make it, I'll buy.

My only complaint here is that I recently moved my valve inside for better eye balling of the inevitable failure... Could have saved all that hassle! Haha
Any chance this system could be adapted for a valve sitting on the inside hoses?
Maybe with a longer/stiffer purge hose to pass through the heater hose rubber grommet into the van
My cooling system is still empty for the motor swap and I'd love to get this in there before getting it back on the road
