I have used two different aftermarket radiators, 2 and 3 row and of course the original. I have noticed a bit of a temp difference with the 3 row radiator that I got from Rob Lately I have been using a lot of the NOS units. I just put one in yesterday in a car that the original went 286,000 miles. So far I have not had any problem with any radiator but do watch the 2 row aftermarket ones as some of them don't quite bolt in the same although its close enough. So I guess this really doesn't answer the question of which is better but I am satisfied with the 3 row or the NOS and will use them as I see fit. In a nice car for show definitely the NOS for refurbished cars or daily drivers its up to you Ken [Non-text portions of this message have been removed] 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!
