I have a 02 2500 hd w/a 6l truck is 4wd and I do alot of towing from cars to boats and tractors.Has anyone swapped from the clutch fan to electric fans on these trucks.I know the fans will bolt up directly from gm but none of our 07-08 2500,s have the electric fans. Gm doesnt have them on the 2500,s yet.Just curious if towing in 100 degree weather in traffic would be a problem?Any suggestions would welcome.I can buy a complete gm set up for about 450.00
