What wonderful idea as compared to adding switches and other good stuff.
Yep, just crack the throttle. I also do this on my Diesel motor home as it
will also over cool going down long grades. And there is no actual
throttle there. Only fuel is regulated so going down those hills the full
engines capacity of air with no combustion cools it down really quick.
 There is the advantage though that this quickly gets rid of that extra
heat generated going up the hill.

Hello group........

I don't know if it is related but the only two times I've experienced
Vanagon Syndrome has been after coasting down to the bottom of long long
grades. I would hit the throttle at the bottom and nothing would happen -
just sputtering. I'd pull over, stop the engine, restart and all would be
OK.

FWIW - this is the only problem I've ever had with this van after four
years
and twenty thousand or so miles.

My "cure" has been to modulate the throttle as I coast down any long hill
in
my automatic '87 Westy.

I haven't experienced the syndrome since.
