Hi everyone i have a 2015 gmc sierra 2500HD

if anyone in this form can help me with a electric fan conversion instead of that clutch fan its better if someone knows how to do it with the OEM ecm

I'd be interested in same for a 2017 W/T.

I looked into it and didn't find any simple solutions or kits.

Some say they're less efficient towing / hauling in extreme hot weather. Maybe that's why.

It sure would be nice most of the rest of the time to have the benefits of the electric fan if a quality kit was available.

Hi all,

I am also searching on this topic, and found out that the help to keep the A/C cooling better on low engine RPM, and some other benefits like increasing HP (Up to 10 hp, this has to be proved). I found some tutorials in YOUTUBE were you can control them by PCM module (AS stated here). Something that tells me that they really work is seeing all this trophy trucks running in Baja 1000 with electric fans cooling water and oil on a dusty hot enviroment. Dorman is a reliable brand that sell this conversion kits.
