Re: [T3] Air Cooling Control

Those "nuts" are welded into place on the tin, you have to pull the
tin screws off from the top, not easy to do with the engine in place.
I usually use a pair of needle-nose vice grips to get hold of the
screw heads from under and in front of the engine and break them
loose.  Not easy to get back in, either.  I think you can "just" get
on a couple of them with a very long screwdriver from the top, it's a
strain, though.  Been a while since I've had to do that, I usually do
tin removal with the engine out.

OK, as to the main question, there's a bellcrank under the right top
engine tin,a spring goes to the flap and to the pivot on the
bellcrank(stationary end).  This pulls the flap open. Then there's a
shaft from the flap to the bellcrank with an adjustment clevis on the
crank that's the same as is used on the heater boxes. There's a shaft
>from the bellcrank going down through the cooling fins on the head
that the thermostat on its bracket screws into.  I really don't know
if the shaft would be visible from the bottom if the spring has the
flaps held open and no thermostat screwed on.  The bellcrank bracket
is secured under the middle two upper head stud nuts.  The thermostat
bracket is roughly like a square O.  If you haven't seen the setup in
person, like at a junk yard, it's no wonder you're having troubles.
Took me a while and a few junk cars to find out how the flap spring is
really supposed to be hooked up.  So, you need at least the bracket
for the thermostat, the bolt that holds it to the bracket and the nut
and washer for the bracket to case stud.  You can get the top engine
tin off with the engine in, it's a bit of a wrestling job, you have to
take the right side manifold tubes off with the injectors(if you have
FI, you didn't say), and all the little tin bits around the spark
plugs and fan outlets.  Don't drop anything into the head intakes or
you'll be very sorry.  Plug with some clean rags while playing around
there.  Probably someone on the list here has the spares you'll be
needing.  Bentley does have some pictures of the linkage, not too
detailed, and of course it has the proper procedure for adjusting the
flaps.
