I blocked the horn holes, had the radiator cleaned, added a smaller water
pump pulley and a 13" flex fan.
My stock MKI went from running 215 F to running 190 F on hot days in
traffic.
I did all this for about $75. Well worth the time, money and effort since
the cabin temperature decreased as well by approximately the same amount.

Hi Owain,
I see Michael has already posted the main part of the answer. I would just
add that there were positive results from such a change in the in-depth
cooling study a few years ago that is posted on the TE/AE website.
http://teae.org/cooling-the-tiger/ Somewhere deep in the study they report
positive
results with conclusions similar to Michael's.
Anecdotely speaking, I would say my Fairmont pulley has been helpful. I
have heard others who have used it report similar favorable results. That,
along with running the engine distributor vacuum advance off manifold vacuum
instead of ported vacuum and a six bladed fan have been especially helpful
for me with the idle and low speed cooling. And that was after putting in a
recored radiator.

Subject: Re: [Tigers] Reduced diameter water pump pulley
Hi Gene,
What's the motivation? I could understand _increased_ diameter for high
revving engines, but why smaller? More water flow is unlikely to aid cooling
and could make it worse. Recirculating airflow is the only issue I've
encountered with tiger cooling whatever the engine or climate if the radiator
works properly.
