2019 Engine fan alway on

[R.Taylor]

I've noticed that my 19's fan is quite a bit more active than my 18's was. My 06' seemed to only engage when the AC was on.

It's my understanding these 4th gen fans are electrical?

Rams, glad you got it all worked out and taken care of!!!!

not sure on the cummins . 6.4 has two fans. electric and mechanical with viscous clutch

Cummins is Vistronic only, always and ever.

Maybe its normal, I have a slight fan noise on all the time as well but it not steady. Up and down. Not a roar like a cooling fan. At first I thought it was the turbo, hear it at low speeds mostly.
