Alan, your radiator/fan setup is in the same position as mine. The fan is not automatic, there's a switch on the dash for that. Overheating is never really an issue (other than in the cockpit! ) and if the engine does get a bit too warm in traffic, then a few dribbles on the road is the result Non of this unnecessary weight with expansion tanks! Your picture did bring back memories though of a French agricultural garage doing some delicate welding to the broken top stay on the radiator, in the middle of nowhere, on a Saturday afternoon! Job done, payment refused and on our way again touring rural France. His work is still pretty solid today! Then there was the blown headlight on a Le Mans trip... ... and the failed generator/regulator on another Le Mans trip... I could write a book
