[T3] Thermostat Air Flap

[Keith Park]

I might add that the Bentley has a pretty good section on how it goes
together and is adjusted.  The correct spring is important, and how it hooks
on is too... things are adjustable with how far the pushrod screws into the
thermostat AND the flaps rod attaches to the pivot.

Subject: Re: [T3] Thermostat Air Flap

 Having spent most of the afternoon working on hooking up the thermostat and
the air-flap rod and so forth...it's finally all installed. Haven't yet put
back the tin and everything though...pending any advice here.

Using small needle nose vice grip pliers to hold the tiny circlip to shove
it onto the flap rod end...that worked.  Almost easy, despite hard to
reach.  Small mirror and flashlight help...and a magnet to find lost
circlips, .      BUT things aren't right.


The thermostat is mounted below and screwed all the way onto its rod. Doing
that brings the flap-rod, above, as close as possible to where it anchors to
the assembly.      BUT...to get the rod in the anchor enough to tighten the
little bolt, the flap ends up almost all the way open.   According to
Bentley, it should only be open a fraction of an inch.

 I'm assuming that when adjusting all this, the engine is cold (though its
in upper 80s today), and the thermostat is in most-compressed state.   It
expands when heated, right?  
    But the thermostat takes up all the up-and-down space in its bracket.
Where can it expand to?   Is that top extension (with the hole to screw into
the rod) supposed to ride up and down in its notch as thermostat temperature
changes?  As it is, it can only go down.

Another ominous problem (besides flap rod not being long enough) is that the
spring is too long...by about an inch.

So....maybe the question is....Is this the right thermostat and assembly for
a 72 standard engine?    I have a 73 parts car out back. But I'll bet
there's no thermostat etc there to look at.   

This is all new turf...having only removed  thermostats and the rest from
every T 3  I ever did engine work on....wiring up the flaps, of course.   
Never installed one.   I'm searching Samba...but nothing helpful yet.
