I used to have overheating problems...car used to run mostly around 230-240....got it lower and lower over the years , by fillers , water pump, timing, carburator etc..(and actually got rid of an electric 'helper fan' , placed in front, it was just blocking more than it helped)..but last item was a new 3 core alum radiator by Champion...now car runs 185-195 from colder time of the year to the hotter times.
Personally I dont like the electric fans (have had on other vihicles) as they tend to "whine" too much.
