Just a comment: My D has a 100% original cooling system, bar the expansion bottle, recently replaced before our trip to LeMans. In 38 degree C heat, AC on full, queueing up for over an hour in Arnage my car had no trouble keeping the temperature to the same level that it does on a cold miserable English day :-) I am all for more efficient fans to remove some of the load on a weak electrical system, but additional flow is (IMO) not really necessary until you start running more power and generating more heat Martin #1458 (17,000 miles and counting - 14500 done since 2001) To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
