Well I know there is a valve in the coolant on two of my three A1s. (Now
ask me once again how much I love those friggin spring clamps that hold
them on)
So I was asked if it totally cuts out the flow to the core, and I don't
know for sure, but looking at the structure of the valve I'd guess it's a
pretty total blockage. The one I honestly don't know about for sure is my
Mk I, and I have to confess, I assumed it to be like the MkiI and the
cabby. So I'll go check that. As for air flaps, I don't know how they're
set up, but I'm going to have to figure that out soon on the Cabby. (The
controls are broken)
I've been wanting cool air for some time on the headache, and in addition
to that valve malfunctioning, I have no vents over the rain tray. Anyone
know a good aftermarket source for a small tasteful grille or scoop that I
could insert into the hood to get some cool air to the vent intake? This
is for an aftermarket hood.
