<DIV>Well, no one can fault you for not trying. A very comprehensive test.</DIV>
<DIV> </DIV>
<DIV>I know this has been long running so forgive me if this has been said
before. The holes on the left and right of the radiator have been found to bleed
back air already passed through the radiator to recirculate at idle. People have
made block off plates to prevent this from happening. I’d think that cardboard
and tape would suffice for testing.</DIV>
<DIV> </DIV>
<DIV>I’ve also heard that air passing under the car (at speed) impedes air
getting out of the engine compartment. The black garden edging, round on
one end has been used to make an air dam that mounts to sway bar. The
round portion is slit at the top and slipped over the bar. Then slots are cut
just under the round part for hose clamps to pass through to secure the edging
to the bar. The theory is that the air passes around rather than under the
car and the negative pressure draws the hot engine compartment air out.</DIV>
<DIV> </DIV>
<DIV>Does this work? Will this help? Who knows? But it is relatively easy and
wouldn’t take too much time. As with any modification, do at your own
risk.</DIV>
<DIV> </DIV>
<DIV>Lastly, if originality isn’t important (at least for testing) the older
German cars like Audi, BMW etc. typically have a plastic expansion tank. At a
self serve wrecking yard, they are probably $10-ish. You might find something
that is adaptable if going that route is an eventual path.</DIV>
