Electric Fans

[hatman74]

Anyone tried replacing you radiator clutch fan with electric radiator fans? I have a 2018 GMC 2500HD 6.0. Anyone tried this?y

go on google, there are tons of info on this subject.

 

the electric fans do not move the air that your clutch fan does, when i was researching for my old duramax 5 years ago.

Off topic, that is a great looking set of toys!!!

i personally feel the mechanical fan is superior to the electric fans, if you got a tow rig.  they always pull air, and your AC will always be efficient.  arm chair hot rodders just think the electric fans are better.  if you have a viscous clutch inline than the mechanical set up is perfection!!

if you want to do some crazy stuff, delete the motor t-stat, and with HPtuners just set your low and high end on/off temps, but this would work best with grill shutters i'm thinking...

AC on my 2003 with a mechanical clutch fan was garbage when not moving. Electric fans are massively superior. No way that one shitty fan that can be stopped by a fried clutch that is dependent on engine RPM can outflow a pair of electronic fans. And I cannot recall hearing of an electronic fan failure on these trucks.

probably chinese outsorced clutch parts.. mechanical is a better design i cant help GM buys sh*t components these days

 

 

there is a reason GM uses a mechanical system on the HD trucks..they've done the research and know whats best

The reason is cost. They run e-fans on the 1500s to help meet MPG targets. HD trucks aren't subject to CAFE regulations so they don't care. They don't run them because they're better.
