Easy partner, remember your blood pressure.
All I am saying is that electric fan(s) did not work for me and no there were no other engine issues. My BBM 512 would get hot at slow speeds until I converted it to a 18 inch 7 blade Mopar fan set up, never got above 195 again even with the A/C on.
Many others members on FABO have had the same experience.
I don't have issue with a good mechanical clutch fan setup but I will just agree to disagree on the other points.
