Though implied, I meant:
"I installed a shutoff valve. In my Vanagon, fan not
withstanding...... " Re: flaps, was suggesting that if one had poor
flap seals, a shut off valve would be pretty much useless. IMO.
:)

Not *too* hard to get at, but a poor location. As I noted, the engine
bay area is better. That said, I rebuilt my heat exchange box during
engine swap process. It seals quite well so I can shut off air flow. I
will do things differently (read: better) on my next air to water
cooled swap. (next? Ha ha ha)
In my case, installing the Home Depot shutoff valve was all part of
the engine swap process. The *new* Vanagon valve leaked from day one.
In terms of valve location, I debated which heater core hoses to use.
Diesel or WBX. The former would have put the valve in the cab.
Installing the valve where I did was an oversight for sure. I had a
lot on my mind during that time. :)
